Anchor Roma 4M Metal Box

Product Details

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.
