The box includes an integral earth terminal and carries an IP20 rating for protection against solid objects over 12.5mm diameter, making it suitable for surface-mounted industrial, workshop and outdoor electrical installations where flush mounting is not practical.\u003c\/p\u003e\n\u003cp\u003eDesigned for pairing with metal clad switches, sockets and accessories, the back box surface-mounts to walls, timber posts and concrete surfaces using the four corner fixing points. The 44mm depth accommodates standard single-gang wiring requirements including cable entry knockouts on all four sides and a bottom cable entry. The powder-coated finish resists corrosion in workshop environments and under light weather exposure when paired with appropriately rated accessories.\u003c\/p\u003e\n\u003cp\u003eThe steel construction provides mechanical protection for wiring in high-traffic areas, garages, outbuildings and light industrial spaces where surface wiring is preferred over chased-in installation. The box ships empty without a faceplate — pair it with any Knightsbridge metal clad 1-gang accessory (switches, sockets, isolation switches) to complete the installation. The 25-year warranty covers the back box itself; faceplate warranty terms depend on the accessory fitted.\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\u003e78 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e78 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e44 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePremium grade steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eI\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\u003eNeon Indicator\u003c\/td\u003e\n\u003ctd\u003eNo\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_1328790_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_1287772.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between a metal clad back box and a standard plastic back box?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMetal clad back boxes surface-mount to the wall and provide mechanical protection for the wiring and accessory, making them suitable for workshops, garages and industrial spaces.
