ABSTRACT:
The apparatus includes a drill guide for use during the installation of locksets in doors. The guide has a body with preferably two recesses formed on the flat faces of opposite sides of the guide. One of the recesses has a flat base for straight-edged doors and the other has a sloped base for beveled-edged doors. An aperture extends through the body from recess to recess and is centered relative to the recesses so that the flat face serves as a guide for drilling pilot holes on the face of the door, while the recesses selectively serve as self-centerable guides for drilling pilot holes for either straight- or beveled-edged doors. A drift punch can be inserted into the edge pilot hole after the face hole has been made so that upon closing the door and urging the drift punch into the jamb, a mark will be made which is the center of the strike hole. The present guide is also usable in an improved method of installing locksets in doors by marking the center of the lockset location, placing the guide at the mark to drill a pilot hole, drilling a face and edge hole by using the pilot hole, and thereafter attaching the lockset.
