When the screw is loosened the upper plate and thus the hinge pin may be pushed up, or permitted to drop into place. By tightening the screw the hinge pin is locked in its extended position and the screw head is flush with the bottom of the fixed plate. The bottom hinge pivot assembly includes an L-shape bracket with the vertical leg secured to the frame and the horizontal leg beneath the door. A threaded stud on the horizontal leg threadedly supports a nut-pin assembly with the upwardly projecting pin surrounded by a flat shoulder. A thrust washer on the shoulder supports the weight of the door and the door may be height adjusted by rotating the nut-pin assembly on the threaded stud and locking it in position.
