I needed a wall hanger for my guitar and ukulele; therefore, I bought 2. It hangs easily with just 2 screws, so there is minimal wall damage, and you can easily cover the small screw hole when you decide to take the hanger off the wall. The hanger is pressure activated which is great for those that forget to flip the lock levers. When I sit my guitar and ukulele on it, the locks flip inward. When they flip, it automatically locks the instruments into place which means that they will not fall off into the floor. The foam is high density and high quality! This hanger, saves my instruments from damage and saves space because I do not have to pile instruments into there.
