Query: Decent locking device.

The main components of this device will perform adequately, but the lock is about as secure as a cotter pin. Well, the cotter pin would probably be more difficult to remove than the lock. The wing nut that was supplied with the device was not tapped correctly so the wing nut must be angled to start the threads, which in turn causes the nut to wobble as it is tightened.
