Abstract
A hollow keeper housing is secured to the header or sill of a door of a truck trailer for receiving a generally arcuate camming finger disposed at the end of a rotatable vertical lock rod. The camming finger and keeper housing are designed so that when force is applied against a latched door, a relatively flat surface of the camming finger is tangent with the inner camming surface of the hollow keeper housing at a point located a distance from a plane parallel to the line of force and passing through the axis of rotation of the lock rod, the distance providing a torque in a latching direction.
