Hager 780-057HD 79 Clr Continuous Geared Hinge 79 in

Product Description

The HAGER 780-057HD 79 CLR is a full surface continuous geared hinge designed for heavy-duty door applications. Running the full height of the door at 79 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 maintaining consistent alignment over time. The satin aluminum clear anodized finish provides corrosion resistance suited to high-traffic commercial environments. This hinge is installed by commercial door and hardware technicians as well as licensed carpenters working on institutional or commercial projects.

Full surface continuous geared hinges like the 780-057HD 79 CLR are used on heavy commercial and institutional doors where standard butt hinges are insufficient. Typical applications include high-traffic corridor doors, restroom doors, classroom doors, and other openings subject to frequent or forceful use. The full surface mount means both leaves attach directly to the face of the door and frame without mortising, simplifying installation on hollow metal or wood doors in new construction and retrofit projects alike.

Key Features

• Full surface mount design eliminates the need for mortising on door or frame
• Continuous geared mechanism distributes load across the full 79-inch door height
• Heavy-duty construction rated for high-cycle, high-traffic commercial applications
• Synchronized gear action maintains consistent door alignment and reduces edge wear
• Satin aluminum clear anodized finish offers corrosion resistance and a neutral appearance

Compatibility

Designed as an OEM-style full surface continuous hinge replacement or new installation component for commercial and institutional doors requiring heavy-duty, full-height hinge support.

Installation Notes

Installation should be performed by a qualified door hardware technician or licensed carpenter familiar with commercial door and frame assemblies. Power down any electrified hardware associated with the door opening before beginning work. Both leaves are surface-mounted with fasteners to the door face and frame face, so proper fastener selection for the substrate material is critical to load-bearing performance. Verify local building and fire code requirements, including any applicable NFPA or IBC provisions, before installing on rated door assemblies.
