Two screws are threaded into two holes in a hinge arm which is adapted to be assembled with a base plate by shifting the arm longitudinally to cause the screws to slide into two U-shaped slots in the plate, the slots permitting longitudinal adjustment of the hinge arm. One of the screws may be turned to adjust the inclination of the hinge arm relative to the base plate while the other screw serves to lock the arm to the plate.
