Hager 780-157HD-CLR-83 Continuous Geared Hinge Heavy Duty

Product Description

The HAGER 780-157HD-CLR-83 is a full surface continuous geared hinge built for heavy duty door applications. Continuous hinges, also called piano hinges, run the full length of the door edge and distribute load across the entire hinge line rather than at two or three isolated points. This design reduces stress on the door frame and leaf, extending the service life of both the door and the hardware. The 780-157HD-CLR-83 features a satin aluminum clear anodized finish, which resists corrosion and maintains appearance in high-traffic environments. It is installed by door hardware specialists, commercial carpenters, and general contractors working on commercial or institutional projects.

This hinge is suited for commercial and institutional door applications where standard butt hinges are insufficient. Heavy duty continuous hinges are commonly specified for high-frequency swing doors, corridor doors, and entry doors in schools, hospitals, government facilities, and other demanding environments. The full surface mount configuration allows installation directly to the face of both the door and the frame without the need for mortising, simplifying the installation process on both new construction and retrofit projects.

Key Features

• Full surface mount design eliminates the need for mortising on door or frame
• Continuous geared mechanism distributes hinge load across the full door height
• Heavy duty construction rated for high-cycle, high-traffic door applications

Compatibility

Designed as an OEM-style full surface continuous hinge replacement or new installation component for commercial and institutional door assemblies requiring heavy duty continuous hinge hardware.

Installation Notes

Installation is typically performed by a licensed door hardware installer or commercial carpenter. Before installation, ensure the door is properly supported and the opening is plumb and square. Fasten the hinge to both the door face and the frame face using appropriate fasteners for the substrate material. Follow local building codes and door hardware manufacturer guidelines for fastener spacing and door preparation requirements.
