The Decora® brush pass through insert offers a clean, professional appearance when cable needs to pass through a wall opening. The white fibers of the brush protect the cables and close the opening to provide an aesthetically pleasing look. The brush insert installs on standard NEMA electrical boxes and low voltage brackets. Single or multi-gang Leviton® Decora® wallplates (sold separately) complete the installation. Use for home theater, classroom or conference room audiovisual installations.
