WireTray is designed to install under or behind your desk to organize and conceal all the cords, cables and wires, and to get them off of the floor. Installation is simple - all you do is assemble the 15 hooks into the channel, and attach under your desk or work surface with the 4 included wood screws thru the end caps. Or you can attach to the wall behind your desk by first sliding the hooks into the channel using their other tab. It works great with plug strips, lap top computer cables and bricks, USB, HDMI, printer, and network cables. The design also allows you to rearrange or change your wires as needed, and the wires can enter and exit where desired. The hooks also make it easy to weave and contain all those long loose wire loops. If you need it longer just purchase another one. If it’s too long, cut it with a saw to the desired length. U.S. Patent No. 8,596,588.
