This faceplate is designed for two keystone jacks (not supplied) which snap in from the rear.
The white faceplate comes in two parts. The rear of the faceplate screws into a standard single gang UK electrical back box with the screws supplied, then the faceplate snaps on to the rear to give a screwless appearance.
Two sprung shutters conceal the keystone jack apertures and a plastic window protects the ID label above the shutters. The keystone apertures are the standard size of 14.5mm x 16mm and the faceplate measures 86mm x 86mm x 9mm.
