Typical Use & Considerations
Ideal when you are installing a switchboard with one or two modules (switch, socket or data outlet) and you want a metal flush-mounted box craftily installed behind the wall before fixing plate + mechanism.
Use in concealed wiring channels where a recessed box is required: you fix this metal box into the wall or brick/duct, then conduit or wiring enters it, mechanism is mounted, front plate snaps on.
In a location like Chennai / Tamil Nadu (with humid/coastal conditions), the metal box’s rust-protection (zinc coating, GI sheet) is particularly beneficial — reducing corrosion risk for long-term reliability of the wiring assembly.
Using the correct box helps ensure the final switch/socket + plate sits flush, aligns cleanly and flush with the wall surface—important for appearance and function.
---
Things to Verify / Before Purchase & Installation
Confirm the module width requirement: This box is for 1M or 2M modules (one or two adjacent mechanisms). If your configuration has more modules (3M, 4M, 6M etc), select the corresponding larger box size.
Verify the part number and size — ensure it matches your wiring and wall mounting location (use model 21780 for 1/2M metal box).
Ensure your wall back-box / masonry cut out fits the metal box dimensions (approx 7.9 × 7.5 cm) and depth (~4.6 cm) so the mechanism and front plate will sit properly without protrusion or misalignment.
Consider the material environment: While GI sheet metal is good, ensure the mounting region is stable, no excessive moisture or corrosive environment without additional protection.
Ensure your mechanisms and front plates (switches, sockets) belong to the Anchor Roma modular system so sizing, screw alignments, cover plate fit correctly. Using unrelated mechanisms may cause mis-fit.
Secure installation: Make sure the metal box is firmly anchored or embedded, conduit entry is correct, earthing terminal is properly used, wiring is well done — the box is only the shell; wiring quality matter

---
Typical Use & Considerations
Ideal when you need a switchboard location with three adjacent modules (for example: a triple‑gang switch, or two switches + one socket) and you want a metal flush‑mount box that houses the mechanisms behind the wall finish.
Used in concealed wiring / flush mounting installations: The metal box becomes part of the wall/floor assembly before the final cover plate is installed.
Because the material is metal (GI), it provides sturdier installation, good grounding pathway, and better durability in some installations compared to plastic boxes — helpful in homes or commercial settings.
In a climate like Chennai / Tamil Nadu (coastal/humid), using a proper GI metal box helps with structural durability and rust resistance (provided the sheet is properly coated and installation is done right) — but still it is crucial to ensure the wall embedment, wiring treatment and mounting are good.
If your plate and switch mechanism are part of the Anchor Roma range, using this box ensures size and fit alignment — which helps achieve a neat and professional finish.
Things to Verify / Before Purchase & Installation
Confirm you truly need a 3‑Module width (3 M) box. If your configuration has two modules (2M) or four modules (4M) or more, you should pick accordingly to avoid misalignment or a gap under the plate.
Verify the part number / model (e.g., 21452) to ensure you are ordering the correct version (Metal Box 3 M) and matching the rest of your wiring accessories.
Check the internal dimensions and depth of the box: One listing shows depth ~ 46 mm for 3 M GI box.  Ensure the wiring, mechanism behind and plate thickness will fit flush when installed.
Make sure the mechanisms and cover plates (switches, sockets) you plan to install are compatible with the box (Anchor Roma modular series) so fittings align properly — using mismatched series may lead to mis‑fit.
Ensure proper mounting: The metal box must be securely fixed (embedded in wall or anchored) and level, wiring pulled carefully, earthing terminal connected properly, so that the final visible plate sits flush and clean.
Ensure the finish and coating of the metal box is appropriate (galvanised/treated) for your environment — in humid coastal locations, corrosion resistance is important.

Key Specifications & Features
Module size: 4 Modules (4 M) width — designed to accommodate four adjacent modular mechanisms (switches, sockets, etc).
Dimensions: Approximate size listed as 79 mm x 135 mm x depth 52 mm for the 4 M GI box variant.
Material: Galvanised iron (GI) sheet / metal body — e.g., listing mentions “Galvanized Iron (GI)”.
Finish: Rust protected / corrosion‑resistant GI body. Example spec: “Rust Protected 120 GSM GI Boxes … Good quality threads … Tested as per IS”.
Compatibility: Designed for concealed wiring / flush‑mount installations with the Anchor Roma modular accessory system (so switches/sockets/plates of Anchor Roma fit behind this box).
Usage type: For installation of 4‑module wide switchboards where you prefer a metal flush box behind the wall finish.

---
Typical Use & Considerations
Ideal when you have a wall board that needs four adjacent modules side‑by‑side (for example: a row of two switches + one socket + one data outlet) and you want a robust flush‑mounted metal box behind the wall finish.
Useful in concealed wiring installations: the metal box provides structural support, a secure mounting base, and good alignment for the plate + mechanisms.
In a place like Chennai / Tamil Nadu (coastal/humid environment) the galvanised metal body offers better durability compared to low‑gauge plastic boxes, given the rust protection and metal body.
Since the depth is ~52 mm, ensure the back wall or conduit channel supports that depth so the final assembly (box + mechanism + plate) sits flush and level.

---
Things to Verify / Before Purchase & Installation
Confirm that your requirement truly is a 4‑module width (4 M) — if your layout has fewer modules (e.g., 2 M, 3 M) or more modules (6 M, 8 M) you’ll want the corresponding size box.
Check the part number/model for this 4 M version (e.g., listing shows Part No 21791 for 4M metal box).
Ensure the internal depth (approx 52 mm) is sufficient for your wiring, terminals, and mechanism behind the face plate; if your wiring installation is bulky you may need more clearance.
Make sure the mechanism switches/sockets and the finishing cover plate are from the Anchor Roma series, to be fully compatible with this box in dimensions and layout.
Mounting considerations: The metal box must be securely embedded or fixed, levelled, and conduit/wiring arranged properly — even a good box won’t compensate for poor mounting or misalignment.
Check authenticity: Since wiring accessories are safety‑critical, ensure you’re buying genuine Anchor Roma product via authorised distributor, to get correct material quality and rust protection spec.

Key Specifications & Features

Module size: 18 Modules (18 M) width — designed to accommodate eighteen standard modular mechanisms (switches, sockets, data outlets) side‑by‑side.

Part / Model Number: Model 21758 for this 18 M GI metal box.

Material: Galvanised Iron (GI) sheet metal box — described as “Concealed GI Sheet Metal” for this model.

Compatibility: Designed to work with the Anchor Roma modular accessory ecosystem — i.e., switches, sockets and plates of the Roma series. Model listing says “Suit all company plates & accessories”.

Use type: For concealed (flush) mounting — intended to be installed behind a wall/plaster finish, housing the mechanisms inside before inserting the cover plate.

---

Typical Use & Considerations

Ideal when you have a switchboard or gangboard location requiring eighteen modules side‑by‑side (for example a row of many switches + sockets + data outlets) and you prefer a single wide metal box rather than dozens of smaller boxes.

Suitable for concealed‑wiring installations in residential, commercial or hospitality settings where the Switchboard will need many mechanisms and a clean unified finish.

In a climate such as Chennai / Tamil Nadu (coastal/humid), the GI sheet metal body with specified rust protection is beneficial for longevity and stability — though proper sealing, earthing and installation still matter.

Because the width is large (~207 mm), the wall cavity or mounting arrangement must accommodate this size so the final plate sits flush and aligned, and wiring behind has adequate space.

---

Things to Verify / Before Purchase & Installation

Confirm you indeed need an 18‑module width (18 M) box. If your layout has fewer modules (e.g., 12 M, 16 M) you may want a correspondingly smaller size.

Check the part/model number – ensure you’re getting 21758 (or equivalent) for the 18M variant.

Verify internal depth and clearance behind the face‑plate: For example the depth ~60 mm is listed — ensure your wiring, conduit, mechanism terminals all fit within this.

Confirm your plate and mechanisms (switches, sockets) are of the Anchor Roma series — mismatched systems may cause mis‑fit or aesthetic issues.

Ensure the mounting installation is well done: the metal box must be securely fixed, level, flush with wall surface, with proper earthing terminal connected (especially since it’s GI metal).

Check the rust/corrosion protection is adequate (zinc coating/gauge of metal) given your environment (especially in humid/coastal areas).

Buy from a reliable / authorised distributor to ensure you get genuine Anchor product with correct build quality and warranty.

Because this is a large width box, the wall finish, plaster thickness, alignment of mechanism frames, and cover plate need careful planning so the final assembly is professional and clean.

Key Specifications & Features

Material: GI (galvanised iron) sheet metal — offering durability and strength for concealed / flush mounting.
Dimensions (typical): For example listed as 79 mm (height) × 207 mm (width) × 52 mm (depth) for the 6 M size in one spec list.
Rust‑protected / corrosion resistance: The material is described as “Rust Protected 120 GSM GI Boxes” in one listing, which indicates good corrosion resistance for humid environments.
Compatible with Anchor Roma series: Intended to house Anchor Roma modular mechanisms and plates, ensuring alignment and correct fit.
Use type: Concealed (flush) mounting box — designed to be embedded or fixed within a wall or panel before the visible plate and mechanisms are fitted.
---
Typical Use & Considerations
Ideal when you have a switchboard location that needs six modules side‑by‑side (for example: six switches, or a mixture of sockets + switches + data modules) and you want a robust flush‑mounted metal enclosure behind the wall finish.
In a setting like Chennai / Tamil Nadu (coastal/humid), the galvanised metal body is beneficial because of its rust protection and structural rigidity, which helps maintain alignment and longevity of the installation.
Using a 6‑module metal box gives you a clean, unified gang board rather than several smaller boxes, which helps in aesthetics and reduces mis‑alignment across plates.
Since the depth is ~52 mm in one spec, ensure your wall or back‑box / conduit layout supports that depth so that after installation the front plate sits flush and mechanisms are not overly recessed or protruding.
---
Things to Verify / Before Purchase & Installation
Confirm that your need is indeed for a 6‑module width (6 M). If your layout has fewer modules (e.g., 4 M) or more (8 M, 12 M) you should choose the corresponding size.
Confirm the part/model number for the 6M metal box (some listings show model 21463 for 6‑module 6M box for example).
Check the exact internal dimensions (width, height, depth) to ensure your wiring, mechanisms, and plate will fit without crowding. Depth especially matters if the mechanism has thick terminals or cables.
Ensure your mechanisms and front plate are from the same series (Anchor Roma) so that the box, mechanism, and plate align properly — mixing different brands or systems may cause mis‑fit.
Ensure the metal box is properly embedded or fixed, levelled in the wall or panel. Even a high‑quality box won’t compensate for poor mounting or misalignment.
Check material finish and rust protection: Although galvanised, ensure the box you get has proper finish, secure earthing terminal (if applicable) and correct threads for mounting.
Purchase from an authorised distributor to ensure you get a genuine Anchor Roma metal box with correct material spec and build quality — not a lower‑grade imitation.
After installation, the visible part is the mechanisms + plate — but the box behind significantly affects stability, alignment, and ease of future maintenance.

Key Specifications & Features: 8‑Module Variant
Module width: 8 modules (often listed as “8 or 9 M (horizontal)”) — this means it supports eight adjacent modular units side‑by‑side.
Model / part number: Model 30453 is cited for the 8‑module version.
Material: Galvanised iron (GI) sheet metal for the box / enclosure — “Concealed GI Sheet Metal”.
Rust / corrosion protection: The listing mentions “Rust prevention up to 250 hrs. in salt spray test (Red Rust)”.
Dimensions: According to the spec list: 79 mm (height) × 230 mm (width) × depth 52 mm.
Use case: Flush‑mounted installation (concealed wiring) behind a cover plate where you need eight modules width.

---
Typical Use & Considerations
Ideal when you have a gangboard or switch‑panel location requiring eight modules side‑by‑side (for example: a row of switches/sockets/data ports) and you want a single metal box rather than multiple smaller boxes.
Because it’s a quality GI sheet box with rust protection, it's suitable for long‑term installations — especially helpful in humid/coastal climates (e.g., Chennai / Tamil Nadu).
The wide dimension (~230 mm width) means ensure the wall or mounting box behind can accommodate that size — if not, you may end up with misalignment or aesthetics issues.
Using the correct series (Anchor Roma) ensures the mechanisms (switches/sockets) and faceplates will align properly with the box.

---
Things to Verify / Before Purchase & Installation
Confirm you indeed need 8 modules width (8 M). Some listings mention “8 or 9 M (Horizontal)”, which suggests a variant that might fit 9 modules or allow a little extra width. If your layout is 9 modules or you expect one extra slot, verify that variant.
Check the model/part number carefully (e.g., 30453 for 8 M).
Check the depth & internal dimension (52 mm depth mentioned) to ensure your wiring and mechanism behind will fit without protrusion.
Verify the mechanisms and cover plate series (Anchor Roma) so that the plate sits flush on the box and modules align.
Installation must ensure the box is level, properly anchored, wiring clear and back‑box or wall recess is correct; poor mounting will spoil the final finish.
Source from authorised distributor to get genuine GI sheet metal box with correct rust coating etc.

About “9M” variant
While the standard documented size is 8 M for this model, some sources indicate “8 or 9 M (Horizontal)” for the same part/model (30453) meaning the width supports 8 modules, possibly allows a 9th slot or just covers extra width.
If your switchboard uses 9 modules, you should check if the variant supports “9 M” explicitly or if you need a special “9‑module metal box” version. The datasheet list for Anchor Roma GI sheet metal boxes shows “8 or 9 M Horizontal – 79 x 230 mm” in one entry.
Thus, if you have exactly 9 modules, confirm mounting width, mechanism spacing and plate size before final purchase.

Key Specifications & Features
Module size: 12 Modules (12 M) width — designed to accommodate twelve standard modular accessories (switches, sockets, etc) side‑by‑side.
Part / Model number: 21485 for the 12 M GI metal box variant.
Material: Galvanised iron (GI) sheet metal — “Concealed GI Sheet Metal” box.
Rust / corrosion protection: Listing includes “Rust prevention up to 250 hrs in salt spray test (Red Rust)”.
Dimensions: Approx 132 mm × 207 mm for the 12 M size (per one spec table). Depth typically around ~ 56 mm for this module size.
Compatibility: Designed to house modular mechanisms from the Anchor Roma series, ensuring the cover plates and mechanisms align properly.
Use type: Concealed (flush) mounting box — to be installed behind wall finish, then the modular mechanisms and cover plate mounted over it.

---
Typical Use & Considerations
Ideal when you have a wall board or gangboard location with twelve adjacent modules (for example a row of many switches + sockets + data outlets) and want them mounted flush behind a single metal box.
In a concealed wiring installation (say in residential or commercial setting) where you want high‑quality build and durability, this metal box provides a robust support.
In a humid/coastal region (like Chennai / Tamil Nadu) the GI metal box with rust protection is a good choice (for durability, structural stability).
Because the width is relatively large (12 modules) ensure the underlying wall/back‑box and wiring layout is prepared so the box fits flush and the face plate sits cleanly and level.

---
Things to Verify / Before Purchase & Installation
Confirm the module width: Make sure you truly need a 12‑module width box. If your layout has fewer or more modules, pick the correct size accordingly.
Verify internal depth and wall cavity: The box depth (~56 mm in many specs) must accommodate your wiring, conduit entries, mechanism behind the plate so the final assembly does not protrude or sit poorly.
Ensure the mechanisms (switches/sockets) and cover plate you plan to use are of the Anchor Roma series so that they align with this box. Mixing different brands/series can cause mis‑fit.
Check the wall or back‑box is properly prepared and fixed: The metal box must be securely mounted, levelled, and wiring arranged neatly — a high‑quality box doesn’t substitute for good installation.
Purchase from authorised distributor: Ensure genuine Anchor product (correct gauge of GI sheet, proper finishing, earthing terminal if required) to avoid sub‑standard alternatives.
Consider the environment: For humid/coastal areas, ensure good sealing of wiring entries, proper earthing and that the box mounting is secure to avoid corrosion or misalignment over time.

Key Specifications & Features
Module size: 16 Modules (16 M) — built to accommodate up to sixteen standard modular mechanisms (switches, sockets, etc) side‑by‑side in one enclosure.
Material & construction: Galvanised iron (GI) sheet metal box (concealed/flush mount type). Example spec: “Concealed GI Sheet Metal” for model 21736.
Rust / corrosion protection: Specified “Rust prevention up to 250 hrs in salt spray test (Red Rust)”.
Dimensions (approx.): One listing shows 142 mm (height) x 230 mm (width) for the model 21736 (16 M) version. Depth listed around ~56 mm in the specification table.
Material gauge / finish: The specification table shows “Rust Protected 120 GSM GI Boxes” for the series.
Compatibility: Designed for the Anchor Roma series of mechanisms, plates and accessories — ensuring proper alignment of modules, standard module width, and unified installation aesthetic.

---
Typical Use & Considerations
Ideal when you’re setting up a switchboard or wiring board with sixteen modules side‑by‑side (for example, many switches, multiple sockets and data outlets in one row) and you want one unified metal box behind the wall finish.
Used in concealed wiring installations (flush mount) — the metal box is embedded or fixed inside the wall or mounting board, with mechanisms mounted inside, and final face‑plate covering the modules.
Especially beneficial in climates like Chennai / Tamil Nadu (coastal/humid) where rust/corrosion may be a concern: the GI metal box with rust protection adds durability and structural strength.
Because the width is quite large (230 mm approx), ensure that the wall or mounting zone accommodates the width and depth, so you can install mechanisms, frames and plate flush and level.

---
Things to Verify / Before Purchase & Installation
Confirm you really need a 16‑module width (16 M) box. If your switchboard has fewer modules (12M, 8M) or more (18M) then you should select the correct size variant.
Verify the depth & internal space: For the 16 M size, depth is around ~56 mm per spec — ensure your wiring, conduit, earthing, mechanism terminals fit. Using insufficient depth can lead to poor fit or protrusion.
Ensure your mechanisms, cover plate and finishing frame are compatible with the Anchor Roma modular system so the mountings align, screws match, and finish is clean.
Make sure the wall/mounting area is properly prepared — box must be firmly fixed, level, wiring arranged neatly, earthing terminal connected since it’s GI metal. Poor mounting will affect final finish aesthetic.
Buy from an authorised distributor of Anchor / Panasonic Life Solutions India so you receive genuine product, correct material quality (GI sheet, rust protection, finished threads), correct part number (21736) etc.
Since it’s a large gang width, check that the covering plate, frame, and the wall finish coordinate — misalignment will be visually obvious with so many modules in one plate.

Texture / Finish: Smooth surface, neat finish typical for surface mounting in the Roma range.
Weight (one listing): 0.200 kg (200 g) for the 2M variant.
Dimensions (one listing for 2M variant): 9 × 9 × 5 cm.
Depth / size table for 1 or 2M variant: “85 x 85” (mm) depth 40 mm in one spec sheet.

---
Notes & Interpretation
The “height” value is not explicitly separated in all sources, but from “9 × 9 × 5 cm” the height could be interpreted as ~9 cm (~3.54 inches) for that listing (though this may include face/cover part).
The weight of ~200 g is for the 2‑module version in one listing; the 1M version might weigh slightly less.
Texture/finish is described as smooth plastic; it doesn’t appear to have a heavy textured surface or matte finish but a standard clean surface finish for surface boxes.
Because the listing is for a “1 or 2 M” variant, if you use the 1M variant the exact dimensions/weight might differ slightly (less width, possibly lower weight).
The data for “height” is approximate—if you need exact mm/inches for the 1 M version, the manufacturer datasheet would be ideal.

Key Specifications & Features
Module width: Designed to house 3 modules (3 M) side‑by‑side in the modular wiring accessory system.
Part number / model: Commonly listed as 20449 for the 3 M surface box.
Dimensions: One spec lists size: 85 mm × 115 mm (depth ~ 48 mm) for the 3 M version.
Material: High‐impact plastic / PVC body. For instance, “high impact plastics” is mentioned in the Anchor listing.
Surface‐mounted application: Built for surface mounting of modular accessories (i.e., the wiring box sits on the surface rather than fully recessed). E.g., “Surface Box 3M” description.
Manufacturers / brand: Under the brand Anchor Roma (by Panasonic Life Solutions India) in India, aligning with the modular system of switches, sockets and plates.

---
Typical Use & Considerations
Ideal for homes/offices where you want to install 3 adjacent modules (could be a combination of switches, sockets, or other modular units) and prefer a single surface-mounted box rather than three separate smaller boxes or a flush-mounted box.
Good for retrofits or installations where concealed wiring is not possible, and you need a neat surface-mounted solution.
Since it is 3 M width, it gives a clean appearance with space for three modular mechanisms side by side, which helps maintain a uniform look in a gang board.
Being a product from Anchor Roma series, it aligns with the rest of the accessories (switches/sockets/plates) from the same range—helpful for visual uniformity in a wiring board installation.
In environments like Chennai / Tamil Nadu (humid/coastal), using a quality surface box such as this with good plastic body and correct installation helps ensure durability and correct mounting.

---
Things to Verify / Before Purchase & Installation
Confirm you indeed need a 3‑module width (3 M) box. If your panel or gang board has fewer (e.g., 2 M) or more modules (4 M, 6 M etc), you should pick the matching size.
Ensure your chosen mechanisms and plates (switches, sockets) are compatible with the Anchor Roma system so the surface box, mechanisms, and cover plate align and fit flush.
Check the depth of the box (for example ~48 mm) is sufficient for your mechanism + wiring behind. The listing notes 48 mm depth for 3 M version.
Verify the finish / colour of the box (usually white/ivory) and ensure it matches or complements your overall switchboard appearance.
Ensure the surface box has appropriate mounting holes/knock‑outs for wiring entry and that the box is fixed securely to the wall or surface. A loose mounting can degrade aesthetics and functionality.
Purchase from an authorised distributor of Anchor Roma to ensure genuine product, correct material, and proper warranty.
Even though this is a surface box only (housing), installation quality (level mounting, proper wiring, secured screws) still matters for long‑term durability and aesthetic finish.

---

---
Typical Use & Considerations
Use this when you need a switchboard or wall panel with 4 adjacent modules (for example: two switches + socket + data plate) and the box has to be surface mounted (not flush).
It’s particularly useful in retro‑fit situations or in constructions where concealed wiring boxes are not available or not desired: e.g., external walls, service rooms, or when you want to mount the board on the surface for aesthetic or practical reasons.
Since it’s part of the Anchor Roma system, if you are already using Anchor Roma switches/sockets/plates (Tresa series) then this box will integrate neatly—mechanisms will align and fit properly.
In a climate like Chennai / Tamil Nadu (humid/coastal), the material (PVC) is good for surface mounting where moisture or wall depth might be challenging. However, ensure proper mounting and sealing to avoid dust or moisture ingress behind the box.
---
Things to Verify / Before Purchase & Installation
Confirm the module width (4M) is correct for your location — if your board only has 2 or 3 modules or needs more than 4, pick the correct size accordingly.
Ensure your mechanisms and covering plates (switches, sockets, data outlets) are compatible with the Anchor Roma system so that they fit into the box + plate properly.
Verify the depth of the box is enough for your wiring, terminals, and mechanism behind it. Although the listed depth is ~50 mm, ensure your wiring doesn’t squeeze or cause protrusion.
Check that the finish/colour matches your other accessories: white or ivory if matching standard but if you have coloured plates you may want matching boxes.
Purchase from a reputable distributor to ensure genuine product, correct material (fire‑retardant PVC), and correct part number (21292) to avoid compatibility or quality issues.
Even though it's a surface box, ensure the mounting surface is stable and level, screws are tight, and wiring is safe. Poor mounting behind will affect the alignment of the cover plate and final look.

Confirm you indeed need the 6‑Module width (6M). If your board has fewer modules (e.g., 4 M) or more (8 M, 12 M) you should pick the corresponding size variant. For example, Anchor lists 4 M PVC surface box as model 21292.

Confirm the depth of the box is sufficient for your wiring behind the mechanisms. The listing shows depth ~ 5.0 cm for the 6M box.

Ensure your mechanisms and cover plates (switches, sockets) are compatible with the Roma series and align with this box size; if you mix series/brands you may get mis‑fit or alignment issues.

Check that the finish/colour of the box matches or is compatible with your face plates, switches and décor. The default white is standard but if you have different finish elsewhere you may want to match.

Installation: being surface mounted, ensure the box is properly fixed to the wall, levelled, screws tight, wiring neatly done. Poor mounting can affect appearance and long‑term reliability.

Buy from a genuine authorised Anchor distributor to ensure you get the correct model (30511), correct material (PVC high impact), and a quality product rather than a lower quality substitute.

If the location is subject to high moisture or external surfaces, consider whether additional protection or sealing is needed even though the box material is decent.

Key Specifications & Features
Module size: The standard 8M version is designed for eight adjacent modular units (modules) side-by-side. One listing even references size "8 or 9 Modules (Horizontal)" for part no. 30704.
Material: These surface boxes are made of high-impact PVC (or flame-retardant plastic) for durability and surface-mounting suitability. Example: “Material: High-Impact PVC” for the 8M box.
Depth & Dimensions (for typical variants):
For part no. 30704 (Horizontal 8 or 9 module): Height × Width × Depth ≈ 8.5 cm × 24.8 cm × 5.0 cm.
For part no. 20450 (8M Square variant) size ≈ 15.2 cm × 14.5 cm × 5.0 cm.
Finish / Use: The boxes are designed for surface mounting (on wall surface) rather than flush installation — useful where recessed back-boxes are not feasible or in retrofit/surface wiring scenarios. Example listing: “Surface Plastic Box … Size 8 Modules” etc.
Brand & Compatibility: Built for the Anchor Roma modular accessory system (switches, sockets, plates) manufactured by Panasonic Life Solutions India Pvt Ltd.. It ensures compatibility of the mechanisms, plates, and this surface box.
Application: Ideal for residential, commercial or retrofit wiring where you require a wider gang (8 modules) of switches/sockets/data modules in one row and prefer surface mount ease.
Key additional details:
One listing mentions the “8 or 9 Modules (Horizontal)” variant 30704, which indicates flexibility for slightly more modules.
The part numbers for 8M PVC box are listed clearly: for example 30704 (Horizontal) and 20450 (Square) in Anchor Roma product list.

Typical Use & Considerations
Use this box when you have a wall panel location that needs eight modules side-by-side (e.g., a row of eight switches or combination of switches + sockets + data ports) and you want a neat unified box rather than using multiple smaller boxes.
Particularly suited for surface installations: perhaps a retrofitted wall, a wall with hard surface, or where you don’t have back-box depth — the shallow depth (~5 cm) is beneficial.
Because it’s from the Anchor Roma system, if you’re already using Anchor Roma switches, sockets and plates, using this surface box ensures alignment, fit and consistent aesthetic.
In a location like Chennai / Tamil Nadu (coastal/humid), having good quality PVC box is beneficial for durability and mounting — but correct installation (firmly fixed box, sealed wiring, good cover plate) still matters.

Things to Verify / Before Purchase & Installation
Confirm you indeed need the 8-module width (8M) or 8/9 modules width variant. If your installation has fewer modules (e.g., 6 M) or more (12 M) then ensure you select the correct size. For instance, I did not find a well-documented “9M” distinct model; the 30704 is labelled “8 or 9 Modules (Horizontal)”.
Check the depth of the box (approx 5 cm) suits your wiring and mechanism behind it; if wiring is bulky, ensure clearance.
Verify the finish and colour of the box (standard white/ivory) and that your cover plate and accessories match this box for aesthetic consistency.
Ensure your mechanisms (switches, sockets) and cover plates are of the Anchor Roma system so the box, mechanism, and plate align perfectly.
Check that the wall surface is appropriate for surface mounting — the box must be securely mounted, levelled, and the wiring secured.

Key Specifications & Features
Module size: 16 Modules (16 M) width — suitable for installations requiring sixteen standard modular mechanisms side-by-side.
Material: High-impact, fire-retardant PVC / plastic body. One listing: “Material: High-impact PVC”.
Finish: Typically white colour in listings. Example: “Color: White”.
Dimensions (approx): For example one listing shows for 16M box – Height × Width × Depth ~ 15.3 cm × 25.9 cm × 5.0 cm.
Series compatibility: Designed to house modular mechanisms (switches, sockets etc) of the Anchor Roma series — ensures alignment with the plate + mechanism system.
Mounting type: Surface-mount (i.e., box sits on the wall surface rather than fully recessed) — suitable for surface wiring or where concealed back-box depth is limited.
Application: Suitable for residential, commercial, and hospitality installations where a wide gang of switches/sockets/data modules is needed.

---
Typical Use & Considerations
Ideal when you have a wall switchboard location requiring sixteen modules in one row, and you prefer a single unified surface-mounted enclosure rather than multiple boxes or segments.
Especially useful for retrofit or surface-mounted installations (e.g., where flush back-box cannot be embedded or the wiring is surface routed) — the shallow depth (~5 cm) is helpful in such conditions.
If you are using the Anchor Roma modular accessory ecosystem (switches, sockets, plates) then this 16M surface box will allow you to maintain visual and functional consistency across board and finish.
In environments like Chennai / Tamil Nadu (coastal/humid areas), a quality PVC surface box helps durable performance — but correct installation (firm mounting, level alignment, proper wiring and sealing) is essential for long-term reliability.

Things to Verify / Before Purchase & Installation
Confirm you really need a 16-module width (16 M) box — if your installation has fewer modules (8M, 12M) or more (18M), pick the matching size accordingly.
Confirm the depth of the box is enough for your wiring and mechanisms behind the plate; the listed depth is ~5.0 cm in one spec — if your wiring is bulky or screw terminals require more space, verify clearance.
Check that your mechanisms and face plates (switches, sockets, plates) are of the same Anchor Roma series so they fit perfectly in the box + plate system — mixing brands/variants may cause alignment or finish issues.
Verify the finish/colour of the box (white shown) and that it matches or complements your covering plates and surrounding décor.
Ensure the mounting surface is suitable for a large surface box — because the width is large, ensure the wall surface is stable, box is level, screw mountings are secure, there’s no warping.
Purchase from an authorised distributor/reseller of Anchor to ensure genuine product with correct material, correct part number (34567 or 34568 for 16M PVC version) and warranty support.
If the location is exposed or subject to dust/humidity (external wall, corridor, utility area), take care of wiring ingress, sealing gaps, and ensure the box is properly anchored to handle environment.

---
Typical Use & Considerations
Ideal when you have a switchboard location that requires twelve adjacent modules (for example: a row of multiple switches + sockets + network/data outlets) and you prefer a single surface-mounted box rather than multiple smaller ones.
Useful in surface wiring scenarios: walls where concealed wiring is not feasible, retrofits, or where the back‐box depth is shallow and you want the box mounted on the surface.
If you’re already using the Anchor Roma modular system, this box will integrate well with the mechanisms and cover plates of the same series — giving you a neat, coordinated finish.
In a humid/coastal climate (like Chennai / Tamil Nadu), using a good-quality PVC surface box helps durability and finish, but as always, proper mounting (secure, sealed, aligned) still matters.

---
Things to Verify / Before Purchase & Installation
Confirm you truly need 12-module width (12M) — if your layout has fewer (e.g., 8M) or more (e.g., 16M) modules you should pick the correct size to avoid mismatches.
Verify the box depth (~5.0 cm in listed spec) is enough for your wiring run, mechanisms, and terminals behind the box. If wiring is bulkier or you need more clearance you may need a deeper box.
Ensure your mechanisms and cover plates (switches, sockets, regulators) are of the Anchor Roma series so that they fit into the box + plate cleanly — mixing brands/series may cause mis-fit.
Mounting surface: Since this is surface mounted, ensure the wall is stable, screws are secured, box is levelled and wiring is neat — poor mounting can lead to aesthetic and functional issues.
Finish/colour: While many listings are white, verify your finish choice (colour, texture) matches your decor and other accessories.
Buy from a genuine authorised distributor to ensure you get the correct part (20347) and authentic build quality — fake or lower quality surface boxes may fail alignment or durability.
If the location is exposed to dust, moisture or public use (commercial/hospitality), ensure the wiring behind is properly sealed and the installation robust — the box gives the housing, but installation quality still matters for long term reliability.
