Hager 780-112HD 83 Clr Continuous Geared Hinge 83in Hd

Product Description

The HAGER 780-112HD 83 CLR is a heavy-duty concealed leaf continuous geared hinge finished in satin aluminum with a clear anodized coating. Continuous hinges, also called piano hinges, run the full height of the door to distribute load evenly across the entire door edge rather than concentrating stress at two or three pivot points. At 83 inches in length, this hinge is sized for full-height commercial and institutional door applications. The concealed leaf design keeps the hinge barrel hidden when the door is closed, providing a cleaner appearance and added resistance to tampering. The clear anodized aluminum finish offers corrosion resistance without painting over the base metal.

This hinge is suited for heavy-duty commercial door installations where standard butt hinges would be inadequate for the door weight or cycle frequency. Typical applications include aluminum-framed doors, hollow metal doors, and wood doors in high-traffic corridors, stairwells, and institutional facilities. The 83-inch length accommodates standard full-height door frames common in commercial construction. Installation is typically performed by commercial door and hardware contractors or finish carpenters working on commercial projects.

Key Features

• Full 83-inch continuous length distributes load across the entire door height

Compatibility

Installation Notes

Installation is typically performed by a licensed door hardware installer or commercial carpenter. The door and frame must be properly aligned and shimmed before fastening the hinge to avoid binding. Ensure all fasteners are appropriate for the door and frame substrate material. Verify local building codes and ADA requirements for door swing force and hardware specifications before installation.
