ABSTRACT:
A universal measuring template for use in in-place marking and locating utility outlet openings, window and door cutouts and the like in construction panels comprising a perforated carrier having a film of adhesive applied to one face thereof. The perforations in the carrier control the ratio of adhesive areas exposed to one transfer surface. A gauge variation is developed within the template by the thickness of material used and the adhesive film. A first adhesive bond is created utilizing the least adhesive area exposed through the perforations on one surface of the template and a second adhesive bond is created utilizing the greatest adhesive covered area on the other surface. The first adhesive bond is developed on a utility box perimeter or other surface area and the second bond is developed on a building panel. A greater bond is developed on the building panel surface due to the greater adhesive covered surface area being extended to said panel surface. Thus, when the template is adhered to a utility box perimeter or other surface the bond created thereon will not be as great as the bond which will be created on the blind side of a building panel when the building panel is pressed against the template. By this construction the template will readily transfer from a utility box or other surface to a building panel.
