The central plate is fixed to a flush-mounting socket outlet using a screw with a combination screwhead (Pz1 slot 1 x 5.5 mm). This central plate is surrounded with a flat edge that is equipped at all 4 corners with a rectangular opening, each containing a multi-positional snap hook. The construction of the central plate ensures that the faceplate can always be attached flat to the wall, even in cases of untidy plasterwork. Finishing colour: bronze coated.
