Commercial Electric 1-gang flexible opening cable wall plate insert works with any 1-gang rocker opening and is used to conceal low voltage cables within the wall, offering a discreet and organized way to manage cables and connect different multi-media devices. Install requires low voltage mounting bracket and a wall plate with at least 1 rocker opening (both sold separately). Patented energy efficient flexible pass-through grommet covers the wall opening, minimizing the loss of conditioned air and providing superior cable management. These wall plate inserts facilitate the passage of cables within the wall while minimizing the visibility of openings and providing a clutter-free appearance for any multi-media setups requiring cable management.
