Abstract
A drilling template for accurately positioning latch holes and lock cutouts in door stiles. The template includes a pair of spaced, parallel, rectangular, frame member that are rigidly interconnected at one end. The frame members straddle a vertical door stile with the interconnecting end firmly against the edge of the stile. Clamps on one frame member are then tightened. A latch hole drilling guide is centered in a plate at the interconnecting end of the frame, and various diameter hole saw guides on removable side plates are positionable at any of a plurality of selected positions along the length of the frame to provide cutout positions for any of many lock backsets.
