A faceplate is configured for covering a wall opening providing access to electrical signal cables. The faceplate itself has an opening leading into the wall opening, and a pair of mounting holes above and below the opening. A cover housing is formed to secure an electrical device within a cavity thereof. The faceplate and cover housing are adapted to provide for the latter being removably secured to the front of the faceplate, after the electrical device is connected to at least one of the signal cables. The cover housing is configured to permit a user to connect a signal cable to the electrical device, and signal cables from the wall opening thereto.
