Hager 780-112HD 83 Dba Continuous Geared Hinge 83 in

Product Description

The HAGER 780-112HD 83 DBA is a heavy-duty concealed leaf continuous geared hinge finished in dark bronze anodized aluminum. Continuous geared hinges run the full height of the door, distributing load across the entire frame edge rather than concentrating stress at two or three knuckle points. This design significantly extends door and frame service life in high-traffic applications. The concealed leaf profile keeps the hinge body hidden when the door is closed, providing a clean sightline and reducing tampering exposure. Licensed contractors and door hardware specialists are the typical installers for this product.

This hinge is suited for commercial and institutional door applications where heavy-duty cycle ratings are required. At 83 inches in length, it accommodates full-height commercial door frames common in schools, hospitals, government buildings, and high-traffic retail or office environments. The dark bronze anodized aluminum finish provides corrosion resistance while coordinating with bronze-tone door hardware schedules. It is installed on both the door and frame leafs and is intended for aluminum, steel, or wood door systems where a continuous hinge is specified.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial finish carpenter following the door manufacturer and hardware specifications. The door must be fully removed or secured before drilling and fastening to ensure proper leaf alignment along the full hinge length. Follow applicable building codes and hardware manufacturer torque requirements for fastener type and spacing. Do not force the geared mechanism during installation, as misalignment can damage the gear track.
