Hager 780-111HD Roton Continuous Geared Hinge — 83" Concealed Leaf, Heavy Duty, Clear Anodized Aluminum

The Hager 780-111HD is an 83-inch concealed leaf continuous geared hinge from Hager's aluminum 780 Series Roton line — one of the most specified geared continuous hinges in commercial construction. Unlike conventional butt hinges that concentrate load stress at two or three pivot points, the 780-111HD distributes door weight uniformly along the entire height of the opening, virtually eliminating door sag, binding, and hinge-point fatigue on high-cycle openings. The concealed leaf design keeps both geared leaves hidden within the door and frame edges when the door is closed, producing a clean pull-side appearance with no exposed hardware and a tamper-resistant profile. Certified to ANSI/BHMA A156.26 Grade 1 and UL fire listed — suitable for rated assemblies requiring a full-height aluminum continuous geared hinge.

Key Features & Benefits

• Full-Height Load Distribution: Geared leaves ride on high-strength nylon bearings spanning the full 83-inch door height, eliminating the concentrated stress that causes butt hinge sag and frame fatigue over time.
• Concealed Leaf (Full Mortise) Design: Both leaves are mortised into the door and frame edges — no exposed hinge is visible on the pull side. Ideal where aesthetics, security, or anti-tamper requirements apply.
• Heavy Duty (HD) Rating: Engineered for doors up to 300 lbs in the highest-traffic commercial openings — institutional corridors, schools, healthcare facilities, government buildings.
• ANSI/BHMA A156.26 Grade 1: Meets the top commercial performance grade for aluminum continuous geared hinges — the specification standard referenced by architects and code authorities.
• UL Fire Listed: Listed for use on fire-rated door assemblies, supporting compliance on labeled openings.
• Clear Anodized Aluminum Finish (US28 / 628): Extruded 6063-T6 aluminum body with a clear anodized finish — corrosion-resistant, maintenance-free, and compatible with standard aluminum storefront and hollow metal openings.
• 1-3/4" Door Thickness: Factory-sized for standard commercial door thickness; verify frame and door prep before ordering non-standard configurations.
• HagerOnHand Express Quick-Ship: This 83-inch length in clear anodized is stocked in Hager's HagerOnHand Express program and ships in 1–2 business days. Non-standard lengths, finishes, and electrified/monitored options carry a 3–4 week factory lead time.

Typical Applications

• High-traffic institutional and commercial doors — schools, hospitals, courthouses, transit facilities
• Fire-rated hollow metal door and frame assemblies
• Openings requiring a tamper-resistant, clean pull-side appearance
• Retrofit of worn butt hinge applications where door sag or frame damage has occurred
• Aluminum storefront and heavy commercial wood-door openings requiring concealed continuous geared hinge support
