This Oversized Cut-In recessed media boxes are used on existing hollow walls and ceilings when you need both GFCI protected power and low voltage cables pulled to one location. The Oversized Box includes a 15 Amp GFCI that is recessed back in in the box so power cords do not interfere with wall mounting your TV. Simply cut a hole in the wall, pull your cables, terminate the power cable, and use the snap-in clips to secure the box to the opening. The finished Trim on the Box makes for a clean wall install.
