Anchor Roma 18M Metal Box

Product Details

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. Rust & corrosion protection: Specified “Rust prevention up to 250 hrs in salt spray test (Red Rust)”. Dimensions: Size listed approximately 207 mm × 207 mm for the 18 M model. Depth ~ 60 mm per spec table. Depth: Appears ~60 mm in one specification set for 18 M box. 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.
