Use the Prime-Line MP9270 wall shield to protect interior walls from impact damage by shielding the point of contact on the wall from a door knob. The shield wall protectors can also be used to conceal small holes in walls and prevent further damage caused by a doorknob. These wall shield protectors are constructed from rigid vinyl. They have a white finish with a paintable smooth surface, allowing you to easily match the protector to any wall. Quickly mount the 3-1/4 in. dia. wall hole covers in place using the self-adhesive backing. Please refer to the line art for dimensions and compare with your needs before purchasing.
