ABSTRACT:
A tool for assisting in determining the locations of disc gates relative to a tailpiece in a combination lock includes a block mounted on a safe handle, a shaft extending from the block, a first pointer extending from the block along the shaft and a second pointer extending from the block perpendicular to the first pointer and across the safe door. The shaft is manually deflectable relative to the first pointer as torque is applied to the safe handle, the amount of torque being visible from the relative positions of the first pointer and an indicator plate on the shaft. Movement of the second pointer is determined by marking the safe door adjacent that pointer, which movement indicates the location of a gate relative to the tailpiece coupled to the safe handle.
