Hager 780-111HD 83 Clr Continuous Geared Hinge 83 in

Product Description

The HAGER 780-111HD 83 CLR is a heavy-duty concealed leaf continuous geared hinge finished in satin aluminum with a clear anodized coating. Continuous geared hinges span the full height of the door, distributing load across the entire door edge rather than concentrating stress at two or three knuckle points. This design significantly reduces door sag and frame wear over time. At 83 inches in length, this hinge is sized for full-height commercial and institutional door applications. The concealed leaf design keeps the hinge barrel hidden when the door is closed, providing a clean sight line and added tamper resistance. Installation and service are typically performed by commercial door hardware specialists or licensed contractors.

This hinge is intended for heavy-duty commercial, institutional, or industrial door installations where standard butt hinges are inadequate. Typical applications include high-traffic corridors, school or hospital entry doors, and other environments where door alignment, durability, and cycle life are critical. The 83-inch length accommodates full-height door frames common in commercial construction. The satin aluminum clear anodized finish offers corrosion resistance suitable for interior applications and blends with aluminum door and frame systems.

Installation Notes

Installation should be performed by a qualified commercial door hardware technician or licensed contractor in accordance with applicable building codes and the door manufacturer's requirements. The door and frame must be properly prepared and mortised to accept the concealed leaf profile before fastening. Ensure all fasteners are appropriate for the frame material and that the door is fully supported during installation to maintain alignment. Verify that the hinge length and hardware specifications meet local fire-rated door assembly requirements where applicable.
