Hager Concealed Leaf Continuous Hinge 780-112HD

Hager - Concealed - 780-112HD Heavy Duty Continuous Hinge

Hager Roton continuous geared hinges are designed to provide superior performance you can rely on in high-traffic areas because they use a unique rotating joint, not a pin. This minimizes lateral wear on the hinge while evenly distributing door weight along the full length of the frame. Roton continuous geared hinges are an ideal choice for new construction or retrofit applications.

Door And Frame Preparation

All Roton Continuous Geared Hinges are surface-applied. Cutout design and spacing coordination is thereby eliminated in both new construction and restoration work. Reinforcement plates are not required in doors or frames except where the gauge is too thin for the fasteners in relation to the door weight or where abusive operation is anticipated.

Door Closers

Conventional surface or concealed sliding closers may be used with Roton. (Note: Pivot type floor closers with a fixed, conflicting pivot point may not be used). Closers will last considerably longer, adjust to operating requirements more readily and show consistent settings due to the reduced operating forces of Roton hinging.
