ABH A240HD-83 HingeKing Concealed Continuous Geared Hinge
The ABH A240HD-83 is a heavy-duty, high-performance continuous geared hinge designed for full mortise (concealed) applications. It is the industry standard for commercial renovations where a seamless look is required between the door and frame. By distributing the door's weight evenly across the entire length of the opening, the A240HD eliminates common issues like sagging, binding, and stress-related hardware failure.
