发明名称 Wall surface protecting bolt support apparatus and method
摘要 A wall surface protecting bolt support apparatus includes a bolt receiving member comprising a plate that has a first side, a second side and a peripheral edge. The plate has an aperture extending therethrough which extends into the first side and outwardly of the second side. A sleeve is attached to and extends away from the second side, the sleeve bounding the aperture. The sleeve has a distal end with respect to the plate. The distal end is open to allow a bolt to be extended through the aperture and through the sleeve. The sleeve is extendable through an opening in a wall surface and the second side is abuttable against the wall surface. The bolt is extended through the bolt receiving member and a head of the bolt is abuttable against the first side of the plate to prevent damage to the wall surface.
