Abstract: A flat plate is used to cover a mounting hole in a masonry wall face and is held in place by a set of wire hooks. The hooks are able to slide into holes in the plate and catch onto the interior surface of the wall in order to hold a clearance hole in the plate concentrically with respect to the mounting hole. An anchor bolt is supported at the center of the mounting hole by the clearance hole in the plate while grout is poured into the masonry blocks thereby assuring that the bolt is positioned properly in accordance with building code.
