Moulded from white thermoset resin, the box measures 86x86mm on the wall face with a 47mm recessed depth, providing clearance for single-gang switches, sockets and dimmers within the CU range. An integrated earth terminal and cable strain relief are built into the rear of the box.\u003c\/p\u003e\n\u003cp\u003eDesigned for flush-mounting in plasterboard, dot-and-dab or solid walls, the pattress box accepts single-gang accessories that require a 47mm minimum back box depth. The curved edge profile of the box matches the rounded corners of CU series cover plates, allowing the accessory faceplate to sit flush with the box edge once fitted. The cable strain relief holds cables in place during installation, reducing movement inside the back box after the accessory is connected.\u003c\/p\u003e\n\u003cp\u003eThe thermoset resin construction is more resistant to deformation under heat than standard PVC back boxes, making it suitable for high-load switches or sockets where the back of the accessory may warm during use. The white finish matches the standard colour of CU series white accessories and becomes invisible once the cover plate is installed. The box carries IP20 rating for indoor dry-location use and has been tested to ISO 22196:2011 for anti-microbial properties.\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\u003e86 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e86 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\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eThermoset resin\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\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\u003eAnti-Microbial Properties\u003c\/td\u003e\n\u003ctd\u003e3rd Party Tested to ISO 22196:2011\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_2301406_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 accessories fit this back box?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CU1610 is designed for single-gang accessories from Knightsbridge's Curved Edge (CU) series.
