This low voltage mounting bracket is designed for installations on existing construction (ie. retrofit applications). Non-conductive, smooth plastic material is perfect for communications, cable TV, computer wiring and audio installations. The open back design allows room for deep mounting depth of volume controls and can accommodate the speaker wire going to it for ease of installation. Additionally, this bracket serves as its own template for cut outs and adjusts to fit 1/4" to 1" thick wallboard paneling and drywall. Specially designed dog-ears flip out when the mounting screw is tightened for a secure fit against the wall.
