Brush Faceplates are commonly used to hide Audio Visual cables
behind walls and so giving a clean appearance to your home rather
than bundles of wires hanging down the wall or trailing around in the living room.

When fitted directly onto a wall without a back box it will sit cleanly flush
with the surface as the brush frame is designed not to protrude past the
back of the Faceplate. This is important if you are fixing direct on to a surface
with no backbox.
