The adjustable hinges GN 238 allow the technically and visually perfect positioning and alignment of a door in its frame.
The steel adjusting disc has a cutting ring in its underside which cuts into the radial fins of the zinc die-cast wings when the countersunk screw is tightened, virtually creating a form-lock that prevents adjusting the hinge after mounting.
The covers conceal the fixing elements and lend the hinge an attractive optical appearance.
