{"product_id":"47mm-single-dry-lining-box-white","title":"47mm Single Dry Lining Box - White","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Knightsbridge 47mm single dry lining box is a white PVC mounting box for installing switches, sockets and other electrical accessories into plasterboard cavity walls. The box sits behind the plasterboard with a 47mm recessed depth, providing clearance for standard switch and socket back plates without protruding into the cavity space.\u003c\/p\u003e\n\u003cp\u003eDesigned for new-build residential and commercial installations where walls are dry-lined with plasterboard over a timber or metal stud frame, the box fixes directly to the plasterboard using red plastic grip lugs that expand against the back of the board when the accessory is screwed in. The 83mm square face matches standard UK electrical accessory sizes, and the 73mm cut-out dimension allows the box to drop into a hole cut with a standard dry-lining saw or hole cutter.\u003c\/p\u003e\n\u003cp\u003eCable entry is accommodated by moulded channels at the top and bottom edges of the box, plus a 20mm knockout at the rear for direct conduit or cable runs through the cavity. The white PVC construction is certified to BS 5733, the British Standard for general purpose cable management boxes, and the box carries a 25-year warranty. The red grip lugs visible in the product image lock the box securely to plasterboard between 9.5mm and 12.5mm thick.\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\u003e47 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_2002324_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 plasterboard thickness does it suit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe grip lugs are designed for plasterboard between 9.5mm and 12.5mm thick, which covers standard UK residential plasterboard.
