This screened Triplex socket from British General has an outlet for TV FM and satellite, with each outlet clearly labelled for ease of identification. The metal housing helps stop RF leakage and signal loss, as well as protecting against impulse noise and EMI/ RF interference which can cause the TV picture to pixelate. As the connection itself is surrounded by a metal housing it also tends to make for a far more secure connection which is less likely to wobble, fallout and break. This Screwless Flat plate brushed steel finish socket has an anti-fingerprint lacquer and a screwless flat plate that clips on and off and sits flush against the wall, making it ideal for modern interiors.
