ABSTRACT:
A method of protecting lock cylinders from being wrenched or pulled from the door, is provided and consists of a plate with a hole in the back top of the plate, which will accept the cylinder. So when the plate is slid up, the cylinder will lock into the milled groove in the bottom back of the plate, locking said cylinder into the back of the plate. There is a bolt hole through the top front of the plate, to allow the top of the plate to be tightened to the door. The cylinder will hold the bottom of the plate tight to the door.
