Abstract: Apparatus is disclosed for repairing holes in hollow walls such as wallboard or sheetrock or the like. The apparatus comprises an interior plate having a positioner guide thereon so that when the interior plate is inserted through the hole to be repaired the positioner guide may rest on one side of said hole as the interior plate abuts the interior surface of the wall and covers the hole. A surface plate is sized to fit securely and firmly into the hole and has retainer clips at each side thereof to retain and position the surface of the surface plate flush with the surface of the wall. A positioner wire extends through both the interior plate and the surface plate and allows the interior plate to be pushed through the wall opening and then to be pulled back into proper position relative to the surface plate. An attaching bolt is extended through the surface plate and engages a nut fixed to the interior plate to securely fasten the surface plate in the hole.
