ABSTRACT:
The present invention provides a templet system including a drilling templet, a sawing templet, and a fastener with an expandable toggle nut to secure the sawing templet to a lath and plaster ceiling or wall panel during the cutting process, and to secure the cut portion of the panel to the sawing templet for removal from the remainder of the panel. The opening formed by removal of the cut portion of the panel is sized to receive an electrical box of a desired shape—either rectangular or octagonal. The templet system allows the lath and plaster panel to be cut without damage to the panel in the area adjacent the cut opening.
