A door hinge assembly includes a frame and a door with top and bottom hinge pivot assemblies. The top hinge pivot assembly includes a plate fixed to the frame and thereabove a parallel vertically movable plate. The upper plate includes a downwardly projecting hinge pin which projects through a clearance hole in the fixed plate. The fixed plate also includes an upwardly extending guide pin which extends through a clearance hole in the upper plate. A screw extends through the fixed plate and is threaded into the upper plate. 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.
