The box measures 146mm wide by 86mm high and projects 30mm from the wall once fixed, giving a total installation depth of 25mm available for cable runs and terminal connections behind the faceplate.\u003c\/p\u003e\n\u003cp\u003eBuilt for residential, commercial and industrial installations where flush mounting is not possible or practical, the box suits applications on stud walls, brick exteriors, workshops and retrofits where surface wiring is exposed. The square edge profile pairs specifically with Knightsbridge's Square Edge (SN) range of screwless faceplates, which clip onto the raised outer rim for a defined geometric finish. The box is also compatible with standard screw-fixed plates from any manufacturer.\u003c\/p\u003e\n\u003cp\u003eThe thermoset resin construction resists impact better than standard ABS plastic and carries anti-microbial properties tested to ISO 22196:2011, reducing bacterial growth on the surface in clinical, catering and high-hygiene environments. The IP20 rating confirms the box is suitable for dry indoor use only. Two brass fixing lugs at top and bottom accept wood screws or wall plugs for masonry. No earth terminal is fitted, so earthing must be handled at the accessory level.\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\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e30 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\u003eNo\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_2002095_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 is the internal depth available for cables?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe box is 30mm deep overall with a 25mm internal depth available for cable runs and terminal connections once the faceplate is fitted.
