Hager 780-112HD 83 Clr Ul-ff-ht Continuous Geared Hinge

Product Description

The HAGER 780-112HD 83 CLR UL-FF-HT is a full-length continuous geared hinge designed for heavy-duty commercial and institutional door applications. At 83 inches in length, it spans the full height of a standard door to distribute load evenly across the entire door edge, reducing stress on the frame and door itself. The concealed leaf design keeps the hinge mechanism hidden when the door is closed, providing a clean appearance. The satin aluminum clear anodized finish offers corrosion resistance suitable for high-traffic environments. This hinge carries a fire rating, making it appropriate for fire-rated door assemblies where code compliance is required.

This hinge is intended for heavy-weight door applications in commercial, institutional, and healthcare settings. The hospital tip profile is specified for use in medical facilities and other environments where safety and cleanability around door edges are a priority. It is suited for installation on aluminum or hollow metal doors in corridors, stairwells, and other openings requiring both durability and fire-rated hardware. Licensed door hardware specialists and commercial contractors typically handle installation on UL-listed fire-rated assemblies.

Installation Notes

Installation should be performed by a qualified door hardware technician or commercial contractor familiar with UL-listed fire-rated door assembly requirements. Verify that the door, frame, and all hardware components are compatible with the fire rating of the opening before installation. The full door and frame must be properly prepared and mortised to accept the concealed leaf profile. Consult the Authority Having Jurisdiction (AHJ) and applicable fire codes to confirm compliant installation of fire-rated door assemblies.
