Hide Cables When Mounting A Flat Panel HDTV
This is possible because the Wiring Solution is made of plaster and medium density fiberboard. This material is typical of most living room walls. The backside is hollowed out with two vertical channels that have a plastic wire retainer that holds the AV cables in place. Each channel is large enough to hold up to five insulated wires.
My Thoughts: I remember being at a friend's house a few years ago and seeing a homemade version of something similar. This is a great option for apartment living or for someone that wants to hide their A/V cables but doesn't want to run them inside the wall.
