Designed specifically for surface-mounted 2-gang socket and switch installations, it provides two single-gang compartments side-by-side in a 173mm-wide housing, allowing a standard 2-gang faceplate to fit across both apertures.\u003c\/p\u003e\n\u003cp\u003eIntended for locations where flush mounting is impractical — masonry walls without chasing, timber stud partitions, trunking runs, or retrofits where cable routing sits on the wall surface — the box raises the socket or switch 30mm from the wall. The integrated earth terminals provide grounding points for metal faceplates and metal-clad cable runs without needing a separate earth block. The box is part of the Knightsbridge Square Edge range but also compatible with other standard UK wiring accessories using 86mm centres.\u003c\/p\u003e\n\u003cp\u003eThe white thermoset resin construction is impact-resistant, non-conductive, and rated IP20 for indoor dry locations. The material is tested to ISO 22196:2011 for anti-microbial properties, making it suitable for healthcare, hospitality and food-preparation environments where surface hygiene matters. The 25mm depth refers to the internal cable compartment space, with the overall projection from the wall at 30mm when 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\u003e86 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e173 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\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_2002097_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 25mm and 35mm pattress boxes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 25mm depth refers to the internal cable compartment space.
