ABSTRACT:
A lock set installation apparatus has a pair of hole saw guides which locate a hole to receive door operating members of a lock set. Each hole saw guide has at least one rail member which oppose one another. A lock bolt hole mechanism is movable and coupled with the rails. The lock bolt hole mechanism centers the lock bolt hole onto the door. A locking mechanism locks the hole saw guides with respect to one another to enable cutting of the door.
