Abstract:

A drill guide for combination lock mounting and method for fabricating and using the drill guide is provided. The drill guide is fabricated using several interior mounting plates bonded together to form a sufficient thickness to maintain a true level bore hole. The fabrication guide plate is attached to a secure door using a threaded clamping device extending through a lock spindle hole. Thereafter, the smaller interior holes are drilled completely through the door. Larger exterior holes are then drilled partway through the door from the outside. The door is then ready to accept an exterior combination lock plate having female studs extending into the door.
