Hager 780-224HD Roton Continuous Geared Hinge — Concealed Leaf, Heavy Duty, Dark Bronze Anodized
The Hager 780-224HD is a concealed leaf, heavy duty aluminum continuous geared hinge from Hager's Roton 780 Series, engineered for the most demanding commercial door openings. Available in 83-inch and 95-inch lengths, this concealed geared continuous hinge distributes door load uniformly along the full height of the opening — eliminating the concentrated stress, door sag, and binding that eventually cause conventional butt hinges to fail. Rated to ANSI/BHMA A156.26 Grade 1 and UL fire listed, the 780-224HD is a trusted specification for high-traffic institutional and commercial applications. Finish: 313 Dark Bronze Anodized (US10B equivalent).
Institutional Grade Features & Benefits
- Concealed Leaf Design: Both geared leaves are concealed within the door and frame edges when the door is closed — delivering a clean, tamper-resistant appearance with no exposed hinge mechanism on the pull side. Ideal for corridors, stairwells, and secured openings where aesthetics and security matter.
- Heavy Duty (HD) Rating: Engineered for high-cycle commercial doors weighing up to 300 lbs, outperforming standard-duty continuous hinges on demanding openings.
- Geared Mechanism: The full-length gear design ensures both leaves rotate uniformly from top to bottom, significantly reducing the force needed to operate heavy commercial doors and virtually eliminating alignment drift over time.
- Eliminates Door Sag: Unlike conventional butt hinges that concentrate stress at two or three hinge points, the continuous geared design spreads load across the entire door height — protecting the door, frame, and hardware investment.
- Fire Rated: UL fire listed, making this hinge suitable for rated hollow metal and other fire-door assemblies per applicable code requirements.
- Extruded 6063-T6 Aluminum Body: Lightweight yet rigid, corrosion-resistant aluminum construction is ideal for high-humidity environments such as hospitals, schools, and correctional facilities.
- Dark Bronze Anodized Finish (313): An anodized finish that is integral to the aluminum, not a coating — providing long-term color stability and corrosion resistance with no paint to chip or peel.
- Fits 1-3/4" Door Thickness: Sized for standard commercial hollow metal and wood door preparations.
- HagerOnHand Express Quick-Ship: Both the 83" and 95" lengths in Dark Bronze Anodized are stocked in Hager's HagerOnHand Express program and ship within 1–2 business days. Non-standard lengths, additional finishes, and electric/monitored variants are available on approximately 3–4 week factory lead time.
Applications
The 780-224HD is well-suited for: high-traffic institutional corridors; school and university entry doors; healthcare facility openings; government and correctional facility doors; stairwell and vestibule openings requiring fire-rated continuous hinges; and any commercial opening where door sag elimination and a clean concealed aesthetic are specified. Architects and specifiers will find this product meets CSI 08 71 00 door hardware requirements for heavy duty geared continuous hinges.
