Recessed low voltage pass through wall plates give your installation a finished appearance but allows you the versatility of using the cable types of your choice. Multiple lines can be passed through a single plate allowing you to mix and match while eliminating the need to have multiple plates spread out across your wall. With these new plates you can install low voltage cables directly behind your flat panel TV, amplifier/home theater receiver, or other audio/video devices. Hole opening on face is 2 15/16" w x 1 15/16" h
