The box measures 146mm x 86mm on the faceplate with a 35mm recess depth, providing a 2-gang mounting cavity for switches, sockets and data outlets where flush installation into the wall is not possible.\u003c\/p\u003e\n\u003cp\u003eDesigned for retrofit and surface-wiring applications in residential, commercial and industrial settings, the pattress box mounts directly onto plasterboard, brick, block or timber walls using the moulded fixing lugs. The rounded-edge profile pairs specifically with Knightsbridge CU-series faceplates to create a continuous curve from the wall surface to the faceplate edge, giving a neater finish than standard square-edge boxes paired with curved-edge plates.\u003c\/p\u003e\n\u003cp\u003eThe box is moulded from white thermoset resin with anti-microbial properties tested to ISO 22196:2011, making it suitable for healthcare, food-prep and high-hygiene environments where surface bacteria reduction is required. The earth terminal is a brass screw post moulded into the rear wall of the box, providing a fixed earth point for metal-framed faceplates and ensuring electrical safety compliance. The IP20 rating confirms protection against finger contact with live parts but no moisture protection, so the box is for internal dry-location use only.\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\u003e146 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\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_2301431_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's the difference between a pattress box and a back box?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA pattress box mounts on the wall surface for surface-wiring applications where cutting into the wall isn't possible or desired.
