No power outlet where you want to mount your TV? No problem. Our installers can save you time and additional appointments with electricians when you choose the Add-On In-Wall Power Extension Kit service. We~ll validate compatibility of the extension kit and installation and ensure that it meets your desired mounting height requirements. Then, we~ll install the outlet portion of the device in a drywall surface behind the TV, run the in-wall-rated jumper cable in the wall between two studs or behind a gas fireplace insert and install the receptacle portion of the kit near an existing power outlet below. When we~re done, we~ll test for power and show you the completed install. Finally, we~ll ensure that all wires and cables are neatly dressed and the workspace is clean when we finish. Best Buy~s TV and home theater services are backed by a 90-day limited workmanship warranty.
