Extend electrical power from an existing wall outlet to the Dual-Purpose Enclosure behind a wall mounted TV without ever needing to modify the home's electrical wiring. The Pre-wired 15A Tamper Resistant outlet secures into the Dual-Purpose Enclosure knockouts allowing for power and AV cables to hide inside the wall and out of sight. | Sanus | | In-Wall Power Kit for TV Media In-Wall Box | White | Best Buy
