The 35mm recessed depth provides clearance for standard switch and socket mechanisms behind the faceplate, while the moulded lugs on each side grip the plasterboard during installation.\u003c\/p\u003e\n\u003cp\u003eSuitable for both new-build and retrofit electrical work, the box accepts single-gang faceplates from Knightsbridge and other manufacturers. The 73mm x 73mm cut-out dimensions match standard UK single-gang switch and socket footprints. Cable entry channels at top and bottom allow wiring to run vertically through stud walls, and a 20mm knock-out at the rear provides additional cable entry from behind the wall cavity when needed.\u003c\/p\u003e\n\u003cp\u003eThe white PVC construction resists cracking during installation and gives a clean finish behind white or light-coloured faceplates. The box carries BS 5733 certification for dry lining boxes and includes a 25-year manufacturer warranty. Knightsbridge supplies these boxes in shrink-sealed multipacks for trade installation projects.\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\u003e83 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e83 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e35 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out Box W\/H\/D\u003c\/td\u003e\n\u003ctd\u003e73x73 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePVC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\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_2002318_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 wall thickness does this box suit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 35mm recessed depth is designed for standard 12.5mm plasterboard fixed to timber or metal stud frames.
