ABSTRACT:
A security door-locking system is described for locking closed doors of tractor cabs on truck tractors, for example, of the type used to pull over-the-road common truck trailers, and vehicles, etc., with similar pre-existing door latching systems. A flat rigid bar has a hole near one end for fitting over the striker pin on the door jamb; and the other end of the bar may be attached to a lock outside the tractor cab after the door is closed. A retainer between the lock and the door/door-jamb provides a secure locking arrangement. And a system like a ratchet provides for attaching the lock to the bar in a tight position with the door.
