I had picked up some Leviton 12-port keystone jack patch panels, and 12-port Monoprice CAT6 patch panels and discovered that the brackets that came with them weren't deep enough to accommodate all the cables behind them. I created this deeper bracket. Print off 2 of the bracket clips, 2 of the backs, and one of the bracket middle. They should all join together. I use a fender washer with these to mount them to a sheet of plywood.
