Measuring 134mm x 134mm, the box is pressed from galvanised steel and fitted with an earth terminal, providing a secure mounting point for both flat plate and screwless grid systems.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and commercial installations where multiple switches, sockets or data modules need to be grouped in a single faceplate, the box sits flush with the wall surface when installed, leaving only the faceplate visible. The 35mm depth accommodates standard grid mounting frames and the wiring requirements for typical 6-8 gang configurations without protruding into the cavity behind.\u003c\/p\u003e\n\u003cp\u003eThe galvanised steel construction resists corrosion in typical indoor environments and provides a rigid frame that prevents the faceplate from flexing under repeated switching. The box includes pre-punched knockout points for conduit entry and fixing lugs for securing to masonry or plasterboard. The IP20 rating confirms the box is suitable for dry indoor locations, and the included earth terminal ensures safe earthing of metal faceplates.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e134 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e134 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e36 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEarth Terminal\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_2201069_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat faceplates does this back box support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe box is compatible with Knightsbridge 6-gang and 8-gang grid faceplates in both flat plate and screwless finishes.
