Hager 780-157 83 Dba Continuous Geared Hinge 83 in

Product Description

The HAGER 780-157 83 DBA is a full 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 pivot points. This design reduces wear on the door frame and door face over high-cycle applications. The dark bronze anodized finish provides corrosion resistance suited to interior and exterior commercial door openings. This hinge is typically installed by commercial door and hardware technicians or general contractors working on hollow metal or wood door assemblies.

Full surface continuous geared hinges are common in commercial and institutional construction where doors experience heavy daily use. Typical applications include corridor doors, stairwell doors, classroom doors, and entry doors in schools, hospitals, office buildings, and government facilities. The full surface mount attaches directly to the face of both the door and the frame, requiring no routed mortise, which simplifies installation on aluminum, hollow metal, or wood frames.

Key Features

• Full surface mount - no mortise routing required on door or frame
• Continuous geared design spans the full 83-inch door height for even load distribution
• Dark bronze anodized aluminum finish resists corrosion and matches common commercial door hardware finishes
• Geared mechanism keeps both leaves synchronized throughout the swing cycle
• Suitable for high-cycle commercial and institutional door applications

Compatibility

Designed as an OEM-style full surface continuous geared hinge for commercial door assemblies requiring an 83-inch hinge length in a dark bronze anodized aluminum finish.

Installation Notes

Installation is typically performed by a commercial door and hardware technician or qualified carpenter familiar with door hardware. Before installation, verify door and frame face dimensions are compatible with a full surface continuous hinge of this length. Fasten securely using manufacturer-recommended fasteners appropriate for the door and frame material. Follow applicable building codes and door hardware manufacturer guidelines for fastener spacing and load ratings.
