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! Stylish design! D-Line On Wall Cord Covers have a decorative half round profile, for a superior finish. Great for hiding wall mounted TV wires, with the profile subtly blending with decor. D-Line Raceway is also used for organizing cords above baseboards, with D-Line appearing as the natural top section of the baseboard. Longer 39-inch lengths supplied per pack, require less connectors versus shorter lengths, to ensure a neat appearance can always be maintained. Accessories included! D-Line Cable Raceway Multipack
