Hager 780-157 83 Clr Continuous Geared Hinge 83 in

Product Description

The HAGER 780-157 83 CLR is a full surface continuous geared hinge finished in satin aluminum clear anodized. Continuous hinges, also called piano hinges, run the full length of the door leaf and distribute load evenly across the entire hinge stile rather than concentrating stress at two or three knuckle points. The geared mechanism links both leaves so they move in unison, reducing wear and maintaining consistent door alignment over time. At 83 inches in length, this hinge is sized for full-height commercial door applications. It is typically installed by commercial door and hardware specialists or finish carpenters working on aluminum-framed or wood-framed door assemblies.

This hinge is intended for full surface mounting, meaning both leaves attach directly to the face of the door and frame without requiring a routed pocket or mortise. That makes it well suited for retrofit installations and new construction alike. The 83-inch length accommodates standard commercial door heights common in office, institutional, and light industrial settings. The satin aluminum clear anodized finish provides corrosion resistance and coordinates with aluminum door and frame hardware commonly specified in commercial architectural projects.

Key Features

• Full surface mount - no mortising required, simplifying installation on existing or new door assemblies
• Geared continuous design distributes load along the full 83-inch hinge length, reducing stress on individual fastener points
• Linked gear mechanism keeps both leaves synchronized for consistent operation and reduced wear
• Satin aluminum clear anodized finish offers corrosion resistance suitable for commercial interior applications
• 83-inch length suits full-height commercial door frames without field cutting in most standard applications

Compatibility

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

Installation Notes

Installation is typically performed by a commercial door and hardware technician or qualified finish carpenter. Fasten both leaves securely using fasteners appropriate for the door and frame substrate material, following the door manufacturer and local building code requirements. Ensure the door is properly shimmed and aligned before final fastener tightening to avoid binding the geared mechanism. Always verify that the door assembly is relieved of load and properly supported during hinge installation to prevent injury and frame damage.
