Hager 780-112LL 83 Clr Continuous Geared Hinge 83 in

Product Description

The HAGER 780-112LL 83 CLR is a heavy-duty, concealed leaf continuous geared hinge designed for full-length door applications requiring both structural integrity and radiation shielding. At 83 inches in length, this hinge runs the full height of the door, distributing load evenly across the entire door edge rather than concentrating stress at two or three points. The lead-lined construction makes it suitable for radiology rooms, X-ray suites, and other controlled environments where radiation attenuation is required. The satin aluminum clear anodized finish provides corrosion resistance and a clean, low-profile appearance. Installation is performed by qualified door and hardware specialists or general contractors working to project specifications.

This hinge is intended for heavy-duty commercial and institutional door openings where continuous hinges are specified in lieu of standard butt hinges. Typical applications include hospital radiology departments, imaging centers, nuclear medicine facilities, and other environments where lead-lined doors are required for radiation protection. The concealed leaf design keeps the hinge mechanism out of sight when the door is in the closed position, maintaining a finished appearance on both the door and frame faces. The geared mechanism ensures smooth, synchronized operation over the full service life of the door.

Installation Notes

Installation of lead-lined door hardware should be performed by a qualified architectural hardware installer or licensed contractor familiar with radiation shielding requirements. The door and frame must be properly prepared and shimmed before fastening to ensure the hinge is plumb and square across its full 83-inch length. Power down or de-energize any electrically powered door hardware in the opening before beginning work. Consult applicable building codes and project specifications for fastener type, spacing, and lead-lining continuity requirements at the hinge location.
