ABSTRACT:
A lock body having compressive engagement with the interior of a hollow structural member of a door, such as a hollow stile. A compressive element is coupled to the lock body by means of a screw fastener. The compressive element has limited rotation about the axis of the screw fastener; the friction of the threaded coupling between the screw fastener and the compression element causing the compression element to rotate about the axis of the screw fastener. Such rotation is limited to approximately 90.degree. by an abutment stop provided on the body of the lock. When the compression element is drawn into abutting contact with the stopping abutment, continued actuation of the screw fastener causes the compression element to traverse the axis of the screw fastener.
