SNAP-ON WALLPLATE SYSTEM

A cover plate device for covering a wall mounted wiring device having no visible fasteners when installed. An attachment device is attached over a siring device to the ears of a gang box using the screws normally employed to attach the wiring device to such gang box. Latch pawls are arranged at the opposite longitudinal ends of the attachment device. A cover plate member overlies the wiring device and gang box and provides a series of recesses to receive the associated pawls in locking arrangement. Because of the number of recesses available at each pawl location, the cover plate can still be installed even if the wall is not flat or even. The attachment member and cover plate member can be provided with various types and numbers of apertures, and the number of pawls and groups of recesses employed depend on the size of the attachment and cover plate members.
