ABSTRACT:
A door for a trailer, container, garage or similar structure carries a vertically movable elongated rod adjacent its free end. A plurality of pins are pivotally mounted on the rod and are adapted to move into locking apertures located on the structure as the rod moves downwardly into its door locking position. The rod can be moved upwardly and downwardly by a manually operable handle which is accessible from the exterior of the door. The door is also provided with a recess within which is located a key lock mechanism for locking the rod in the downward position. The key lock mechanism includes a vertically aligned keyhole which is accessible only through the recess thereby making access to the keyhole by a screw-driver or the like difficult.
