Abstract: A kit for repairing a hole or providing a more substantial mounting for an anchor device, as in a panel of a hollow construction, such as room partition or a hollow door, includes a thin sheet of perforated material which is cut to form a plate slightly exceeding the size of the hole after it has been squared-up. A suitable adhesive, such as two sided adhesive tape, is applied to a face of the perforate plate along substantially the entire periphery of the plate. An operatively rigid tool having resilient legs with feet at adjacent ends, has its legs slight spread apart and the feet inserted through spaced apart ones of the perforations until the legs seat in these perforations and the tool is generally perpendicular to the plate. A rod is then inserted through a perforation preferably aligned with and equally spaced from the perforations receiving the legs.
