Easy to install! No electrical or DIY know-how required to install. All D-Line cable cover lengths have pre-applied self-adhesive backing, for easy peel & stick installation - lengths can be drilled and screw-fixed if preferred. Unlike traditional two-piece cable raceways, the one-piece design of D-Line avoids need to cut lid & base separately. To install, peel & stick to the wall, open flexible hinged lid, add cords & snap shut utilizing patented click-lock design!
