When you use one of these single port or dual port HDMI wall plates from Outdoor Speaker Depot, you'll be able to send premium quality high definition television signals to a flat panel HDTV or projector. An HDMI wall plate will keep cables concealed for a clean, professional appearance. You simply run the HDMI cable from the HDMI outlet of your device to the wall plate. HDMI in-wall cable can then be run from room to room without having ugly cables running along walls and floors. These Decora style wall plates have 1 or 2 female HDMI terminals and are compatible with a standard single-gang J-Box or P-Ring. We also have a 2-in-1 wall plate that can be used to connect an HDMI device and component video at the same time. You can mount these panels onto any part of a wall that you are able to drill into.
