The kit includes the back box housing and mounting sleeve, allowing the fitting to be installed into a cavity wall or external brickwork rather than surface-mounted onto a wall face.\u003c\/p\u003e\n\u003cp\u003eDesigned for both new installations where recessed mounting is preferred and retrofit projects replacing existing bricklights, the kit requires a 197x70x56mm rectangular cut-out to accommodate the sleeve, with the back box itself occupying 190x63x25mm of that cavity depth. Once installed, the fitting projects 14mm from the wall surface with 56mm recessed behind the wall face. The kit is compatible with the BL5BK model and other BL5xx variants in the Knightsbridge range.\u003c\/p\u003e\n\u003cp\u003eThe polycarbonate construction provides impact resistance and weatherproofing suitable for outdoor installation, with the black finish matching the BL5BK fitting colour. The back box design allows cable entry from the rear of the cavity, simplifying wiring runs where surface conduit would otherwise be visible. The 1-year warranty covers manufacturing defects in the back box and sleeve components.\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\u003e100 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e235 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e70 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e14 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e56 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out with Sleeve\u003c\/td\u003e\n\u003ctd\u003e197x70x56 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCut-out Box W\/H\/D\u003c\/td\u003e\n\u003ctd\u003e190x63x25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\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_4096685_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_518900.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat cut-out size is needed for installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe installation requires a 197x70x56mm rectangular cavity cut-out to accommodate the mounting sleeve.
