Captain TJ Underwood from Goldsboro (NC) Fire Department sent in these photos of a recent find on a company inspection. This supplemental lock was found on a department store located in a strip mall. Apparently the store had recently been broken into, so the store owners had a local door company fabricate and install this lock. As you can see from the photo below, the locking mechanism is simply made from galvanized pipe and is designed to pivot into place. Fortunately the presence of the supplemental lock is obvious from the outside due to the visible carriage bolts. Simply cutting into the carriage bolts will defeat the lock, allowing the door to be opened with a simple traditional force to bypass the Mickey Mouse in-handle lock. Plunging the saw straight into the door in an attempt to defeat the supplemental lock will prove to be ineffective due to the distance between the bar and the door, and the limited depth of the blade.
