Hager 780-155HD 83 Dba Continuous Geared Hinge 83 in

Product Description

The HAGER 780-155HD 83 DBA is a half surface continuous geared hinge built for heavy-duty door applications. This full-length hinge mounts with one leaf surface-applied to the door face and the opposite leaf mortised or surface-mounted to the frame, distributing load across the entire door height. The geared mechanism keeps both leaves synchronized throughout the swing cycle, reducing stress on the door edge and frame. At 83 inches in length, it is sized for full-height commercial and institutional doors. The dark bronze anodized aluminum finish provides corrosion resistance suited to high-traffic environments. Installation is typically performed by a commercial door hardware technician or licensed contractor.

This hinge is intended for heavy-duty commercial door installations where a standard butt hinge would be insufficient. Full-length continuous hinges are commonly specified on high-frequency-use doors such as those found in schools, hospitals, government facilities, and commercial buildings. The 83-inch length accommodates standard full-height commercial door frames. The half surface configuration simplifies installation on doors where full mortising is not practical or required.

Key Features

• Heavy-duty geared mechanism synchronizes both leaves for smooth, consistent operation
• Half surface mount design reduces installation complexity compared to full mortise configurations
• 83-inch length spans the full height of standard commercial doors
• Dark bronze anodized aluminum finish offers corrosion resistance and color consistency
• Continuous hinge design distributes door weight and swing stress along the entire door height

Compatibility

Designed as an OEM-style replacement or new-installation continuous geared hinge for heavy-duty commercial door applications requiring an 83-inch half surface hinge in dark bronze anodized aluminum finish.

Installation Notes

Installation should be performed by a qualified commercial door hardware technician or licensed contractor familiar with commercial door hardware standards. Power down any electrified hardware and secure the door before beginning hinge replacement or installation. Proper fastener selection for the door and frame substrate is critical to load rating performance. Follow applicable building codes and door hardware manufacturer guidelines for continuous hinge installation.
