Hager 780-224HD 83 Dba Continuous Geared Hinge 83in

Product Description

The HAGER 780-224HD 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 evenly along 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. The concealed leaf profile keeps the hinge body hidden from view when the door is closed, producing a clean sight line suited to commercial and institutional applications. At 83 inches in length, this hinge is sized for standard full-height commercial door frames and is typically installed by commercial door and hardware specialists.

This hinge is intended for heavy-duty commercial door applications where long service life and high cycle counts are required. Typical installations include office buildings, schools, hospitals, government facilities, and other high-traffic environments where full-height continuous hinges are specified in lieu of standard butt hinges. The dark bronze anodized aluminum finish provides corrosion resistance and aesthetic consistency with common commercial hardware finish standards.

Installation Notes

Installation is typically performed by a licensed commercial door and hardware technician. The door and any associated hardware should be fully removed from service before cutting or mortising the hinge to the door and frame. Proper alignment along the full door height is critical to ensure smooth gear engagement and prevent binding. Local building codes and fire-rating requirements should be confirmed before installation on rated door assemblies.
