Electrical box assembly for angled recessed mounting of high and low voltage components
An electrical device mounting assembly adapted for mounting of power and low voltage components in a shallow wall cavity to supply a television or similar electronic device. The mounting assembly recesses all high and low voltage components behind the wall surface to render them unobtrusive and out of the way. The mounting assembly includes a mounting frame with a peripheral flange, sidewalls, and a rear wall. A corner of the mounting frame is adapted to mount a duplex receptacle at an oblique angle with respect to the sidewalls. The mounting frame includes cable tie-offs for routing cables and at least one low voltage mount for the mounting of low voltage components. The mounting assembly enables consolidation of all power and signal hookups for TV or home entertainment systems in a single assembly that is recessed within the wall and allows flush wall mounting of a flat panel TV.
