Hager 780-053 83 Dba Continuous Geared Hinge 83in Dark Bronze

Product Description

The HAGER 780-053 83 DBA is a half surface continuous geared hinge finished in dark bronze anodized aluminum. Continuous geared hinges span the full height of the door leaf, distributing load evenly along the entire door edge rather than concentrating stress at two or three knuckle points. This design significantly reduces door sagging and frame racking over time. At 83 inches in length, this hinge is sized for standard commercial door applications. The dark bronze anodized finish provides corrosion resistance suited to both interior and exterior installations. Locksmiths, door hardware installers, and commercial finish carpenters are the primary trades that specify and install this product.

Half surface continuous geared hinges are commonly used on commercial hollow metal doors, wood doors, and aluminum-framed doors in high-traffic settings such as schools, hospitals, office buildings, and government facilities. The half surface configuration mounts with one leaf surface-applied to the door face and the other leaf surface-applied to the frame face, simplifying installation in retrofit situations where full mortise work is not practical or desirable. The 83-inch length accommodates typical commercial door heights up to 83 inches.

Installation Notes

Installation should be performed by a qualified door hardware installer or licensed locksmith familiar with commercial door and frame systems. Secure all fasteners to manufacturer specifications using appropriate drill bits and driver bits for the door and frame material. Verify door and frame alignment before final fastener seating to prevent binding. Always consult applicable building codes and accessibility standards, including ADA requirements, when specifying and installing commercial door hardware.
