Features

Expandable Media Box: The Expandable Media Box (45-0051-WH) is designed to streamline power and cable management behind your flat-panel TV. The expandable portion of the Media Box allows for maximum storage hidden behind your TV, while still allowing your TV mount to be flush to the wall.

15A/125V Duplex Receptacle: The Expandable Media Box (45-0051-WH) includes a 15 Amp/125 volt duplex receptacle which mounts inside the recessed media plate using the supplied electrical box. The Expandable Media Box can be installed with the receptacle on the left or right side.

Hidden Storage Cavity: A hidden storage cavity provides additional storage space behind your wall-mounted flat-panel TV. It measures 2.5" (w) x 4.4375" (h) x 4.6875" (d).
