Hager 780-057HD 83 Dba Continuous Geared Hinge 83in

Product Description

The HAGER 780-057HD 83 DBA is a full surface continuous geared hinge designed for heavy-duty door applications. Running the full height of the door at 83 inches, it distributes load evenly along the entire door edge rather than concentrating stress at two or three knuckle points. The geared mechanism keeps both leaves synchronized during operation, reducing wear and preventing binding over time. Finished in dark bronze anodized aluminum, it resists corrosion in high-traffic environments. This hinge is installed by commercial door and hardware specialists, locksmiths, and general contractors working on aluminum or hollow metal door frames.

Full surface continuous hinges at this length are commonly specified for commercial and institutional applications including schools, hospitals, government buildings, and high-traffic retail or office entrances. The heavy-duty designation makes it appropriate for wide or heavy door slabs where standard three-point hinges would be insufficient. The 83-inch length accommodates standard commercial door heights and allows surface mounting directly to both the door face and the frame face without mortising.

Key Features

• Full 83-inch continuous length distributes door weight across the entire hinge line
• Geared mechanism synchronizes both leaves for smooth, consistent operation
• Heavy-duty construction rated for high-cycle, high-traffic commercial doors
• Dark bronze anodized aluminum finish provides corrosion resistance and color-stable appearance
• Full surface mount design installs without mortising into door or frame

Compatibility

Designed as an OEM-style full surface continuous hinge replacement or new installation component for commercial aluminum and hollow metal door assemblies requiring an 83-inch heavy-duty geared hinge.

Installation Notes

Installation is typically performed by commercial door hardware technicians or qualified contractors. The door and frame must be properly aligned before fastening the hinge leaves to ensure smooth operation. Follow the fastener pattern and hardware specifications provided in the manufacturer installation instructions, and verify that the door slab weight and width fall within the rated capacity for this hinge. Always secure the door in an open and supported position before beginning installation to prevent injury.
