ABH A111HD-83 HingeKing Concealed Continuous Geared Hinge
The ABH A111HD-83 is a heavy-duty, full mortise continuous hinge designed for a seamless, concealed installation in both new construction and demanding renovation projects. Featuring a 1/8" door inset, this hinge is specifically engineered to provide a clean, professional look while effectively covering up old butt hinge cutouts in existing frames. By distributing the door's weight evenly across the entire frame, the A111HD eliminates sagging and binding, even on high-traffic doors weighing up to 450 lbs.
