The 86x86mm faceplate footprint matches the standard UK single-gang size, and the 40mm overall depth provides 35mm of cable space behind the accessory faceplate once fitted. The box fits cavity walls, stud partitions and solid walls with appropriate chasing.\u003c\/p\u003e\n\u003cp\u003eDesigned primarily for use with Knightsbridge Square Edge (SN) series accessories, the SN1700 also accepts any standard UK single-gang socket, switch or dimmer that requires a 35mm back box depth. The earth terminal provides a termination point for protective earth conductors without needing a separate connector block. The square-edge profile sits flush with plasterboard and plaster finishes, reducing visible gaps between the wall surface and the accessory plate.\u003c\/p\u003e\n\u003cp\u003eThe thermoset resin construction resists impact better than standard thermoplastic boxes and carries third-party tested anti-microbial properties to ISO 22196:2011, reducing bacterial growth on the surface. The IP20 rating suits dry indoor locations including living rooms, bedrooms, offices and hallways. Knightsbridge backs the box with a 25-year warranty covering material and manufacturing defects.\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\u003e86 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e40 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_2002101_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 35mm and 25mm pattress boxes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 35mm depth provides more cable space behind the accessory plate, making wiring easier on complex installations or where multiple cables enter the box. The 25mm depth is shallower and suits simple single-cable runs where wall depth is limited.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit standard UK single-gang accessories?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The 86x86mm faceplate footprint is the standard UK single-gang size. Any socket, switch or dimmer designed for UK single-gang installation will fit this box, not just Knightsbridge Square Edge accessories.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is thermoset resin and why does it matter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThermoset resin is harder and more impact-resistant than standard thermoplastic (the material used in most budget back boxes). It resists cracking during installation and maintains shape under load, reducing movement behind the faceplate over time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere can this be installed under IP20 rating?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIP20 means the box is suitable for dry indoor locations only. It cannot be used in bathrooms within zones 1 or 2, outdoors, or anywhere moisture or direct water contact is expected.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293961347339,"sku":"SN1700","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/159004_57011c65-9e1c-42e1-8083-1372a00e2caa.jpg?v=1714666891","url":"https:\/\/niori.co.uk\/products\/knightsbridge-35mm-single-pattress-box-with-earth-terminal-white-square-edge","provider":"Niori","version":"1.0","type":"link"}
