The socket provides the primary connection point for incoming telephone lines and includes a built-in surge arrestor and R\/C circuit filter to protect connected equipment from voltage spikes on the line.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and light commercial installations requiring main line access, the master socket allows for line testing and fixed resistance checks without needing to disconnect the wiring. The screw terminals provide secure connections for incoming and outgoing telephone cables, and the socket conforms to BS 5733 standards for telephone outlet installations.\u003c\/p\u003e\n\u003cp\u003eThe 85.75mm square faceplate features rounded edges and a built-in gasket that sits flush against the wall, reducing dust ingress behind the plate. The polished chrome finish on the stainless steel provides a reflective surface that pairs with traditional and contemporary interiors where metallic accents are used across switches, sockets and door furniture. The 25mm minimum back box depth requirement matches standard UK electrical back boxes.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e85.75mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e85.75mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e22.1mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e7.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
