Hager 780-053 79 Clr Continuous Geared Hinge 79in

Product Description

The HAGER 780-053 79 CLR is a half surface continuous geared hinge finished in satin aluminum with a clear anodized coating. Continuous geared hinges span the full height of a door, distributing load evenly along the entire door edge rather than concentrating stress at two or three knuckle points. The half surface configuration mounts one leaf to the face of the door frame while the other leaf attaches to the door face, making it well suited for retrofit installations where full mortising is not practical. At 79 inches in length, this hinge is sized for standard commercial door heights. It is typically installed by commercial door and hardware contractors on aluminum-framed or hollow metal door assemblies.

This hinge is intended for commercial and institutional door applications where high-cycle durability and consistent door alignment are required. The full-height continuous design resists racking and sagging over time, making it common in high-traffic corridors, stairwells, and entrance applications. The satin aluminum clear anodized finish provides corrosion resistance and coordinates with aluminum door and frame systems. Installation does not require mortising into the frame, which reduces labor time on retrofit projects.

Key Features

• Full 79-inch length distributes door weight along the entire hinge edge
• Geared mechanism keeps both leaves synchronized during operation
• Half surface mount - one leaf surface-applied to frame, one to door face
• Satin aluminum clear anodized finish resists corrosion and matches aluminum framing systems
• Eliminates the door sag and misalignment common with three-point hinge sets

Compatibility

Designed as an OEM-style replacement or new-installation continuous geared hinge for commercial aluminum or hollow metal door assemblies requiring a half surface mount configuration.

Installation Notes

Installation should be performed by a qualified commercial door and hardware technician. Secure the door in an open position and ensure the door frame is plumb and square before fastening. Follow applicable building codes and door hardware manufacturer fastener specifications for substrate type. Never force the hinge leaves into alignment - improper installation can bind the gear mechanism and void performance.
