Hager 780-157HD 79 Clr Continuous Geared Hinge 79in

Product Description

The HAGER 780-157HD 79 CLR is a full surface continuous geared hinge designed for heavy-duty door applications. Spanning 79 inches, it runs the full height of the door leaf, distributing load evenly across the entire door edge rather than concentrating stress at two or three knuckle points. The hinge features a satin aluminum clear anodized finish, which provides corrosion resistance while maintaining a clean, professional appearance. Licensed contractors, door hardware specialists, and commercial finish carpenters typically specify and install this product on high-traffic or high-abuse openings where standard butt hinges would wear prematurely.

Full surface continuous hinges are common in commercial and institutional construction, including schools, hospitals, government facilities, and retail environments. The full surface mounting style means both leaves attach directly to the face of the door and frame, requiring no mortising. This makes the 780-157HD 79 CLR well suited for retrofits on existing doors as well as new installations where a mortised application is not practical or preferred.

Key Features

• Full surface mounting on both door and frame faces eliminates mortise cutting
• Continuous geared design distributes load evenly across the full 79-inch length
• Heavy-duty construction rated for high-traffic and high-abuse door openings
• Satin aluminum clear anodized finish resists corrosion and maintains appearance over time
• Full-height coverage reduces door sagging and lateral stress on the frame

Compatibility

Designed as a full surface continuous geared hinge replacement or new-installation hinge for heavy-duty commercial and institutional door applications requiring a 79-inch hinge length.

Installation Notes

Installation is typically performed by a licensed door hardware contractor or commercial carpenter. Verify that the door and frame substrate material and thickness are appropriate for the fastener pattern before mounting. Ensure the door is fully supported and the opening is plumb and square before securing the hinge leaves. Follow applicable building codes and door hardware manufacturer guidelines for fastener type and spacing.
