C.R. LAURENCE P1N337CH CRL Polished Chrome Pinnacle 337 Series Adjustable Wall Mount Full Back Plate Hinge. CRL Adjustable Pinnacle Series Hinges take our popular Pinnacle Hinge to a new level. Adjustment to accommodate the desired angle (up to 90 ) is done after the door is installed. Once the door is hung, simply loosen the Allen set screws and turn the door to the desired closed position. By merely tightening the Allen screws your door will self-center to the desired closed position. The door can swing 90 inward and also 90 outward (adjusting angle from factory set position will reduce 90 swing in that direction). For doors pulling outwards only (using a clear door jamb), you can adjust the hinge to close 5 inside the shower area, thus having the door close snugly against the jamb..
