Abstract
A generally arcuate camming finger is disposed at each end of a vertical lock rod which is rockable about its axis and which extends above and below the edges of a door of a cargo vehicle body such as an enclosed freight-hauling semi-trailer, or a large container for cargo. The lock rod has a horizontally extending operating handle that locks against the outer surface of the door in the conventional manner. As the door completes its closing movements, each finger enters an opening in a hollow keeper housing secured to the header or sill of the door opening, and when the lock rod is rotated exerts a camming force by engagement with a keeper pin to produce the final movement of the door to closed and locked position. The door has a reinforcing rib which carries one half of an anti-rack mechanism the other half of which is associated with a keeper housing which carries the keeper pin.
