Wall Protection Solution
Picture frames are traditionally prepared with a 'hang wire' on the rear. When hung from a hanging system cable, or rod, this standard frame preparation will frequently cause the top of the frame to hang away from the wall.
Here comes the problem, the frame hangs face forward. One of the solutions is to add a pair of Bumpers to the rear lower corners of the frame. These act to create a small space between the wall and rear surface of the frame and lessens the face forward dynamic. It also adds a pleasant floating frame effect.
