Abstract

A lock installation system of template drill and router guides that clamp to the door to prepare doors for locking and latching devices of many different brands. The system uses changeable template drill guides clamped to the faces of the door to drill the cross hole and other specialty holes needed. The edge drilling is done with an attachment for the proper size bit or with a ¼ inch pilot hole and hole saw. The attachment also allows the pre-drilling of the screw holes for mounting the latch assembly. After removing the edge drill setup, there is a router template to cut the mortize for the latch for commercial locksets. There is an attachment for residential locks to router cut the mortize cut out for the latch assembly. The embodiment will work on beveled and square edge doors of the two most common back sets. The embodiment will do door edge center, off set drilling and latch assembly mortizing. There is also a means to help align the embodiment on a door that has a pre-existing preparation. The smaller version of this embodiment is for where the door edge latch mortizing is not required.
