The All Surface TV Hanger installs into any surface in minutes with, no stud or anchor required. The gripping power of the WallDog screw requires no additional anchors, even in concrete or drywall. WallDog anchorless fasteners install with just a screwdriver into drywall or wood, or with a small pilot hole in concrete or brick. Brackets are punched every inch so you can hang your TV in any position along any surface. The patented bracket system is made from aircraft grade aluminum. Great for over fireplaces, in garages or basements, and on any wall in your home. The WallDog is mighty, but leaves only minimal damage in the wall. A built-in level ensures a professional installation every time. Color: Black.
