Hager Hinge 780057HD83CL Bi-fold Roton Hinge 83 in

Product Description

The HAGER HINGE 780057HD83CL is a full surface, heavy duty Roton continuous hinge designed for bi-fold door applications. Measuring 83 inches in length, this hinge spans nearly the full height of the door leaf, distributing load evenly along the entire edge rather than at isolated knuckle points. The clear anodized aluminum finish resists corrosion and blends with standard aluminum door and frame profiles. It carries a UL listing, making it appropriate for installations where fire or life-safety rated assemblies are required. Licensed contractors and door hardware specialists are the primary installers for this type of hardware.

This hinge is intended for commercial and institutional bi-fold door assemblies that see frequent or heavy traffic cycles. Full surface Roton-style hinges are commonly specified on pairs of aluminum-framed doors in schools, hospitals, stadiums, and large commercial buildings where standard mortise or butt hinges would not provide adequate load distribution or cycle life. The clear anodized finish suits applications with natural aluminum door and frame systems.

Installation Notes

Installation should be performed by a qualified door hardware technician or licensed contractor familiar with commercial door and frame systems. Ensure the door and frame are properly aligned and that all fasteners are appropriate for the substrate material before mounting. Verify UL listing requirements with the door and frame manufacturer before installing in a fire-rated assembly. De-energize any electrified hardware in the opening before beginning work.
