Revolutionizing Ligature Resistance in Hinge Solutions
The DH400 Full Surface Geared Hinge prevents ligature risks while ensuring durability and reliability. Key features include:
- Complete Ligature Resistance: The hinge’s full surface design provides a continuous, secure, and tamper-resistant barrier along the door’s edge.
- Heavy-Duty, High-Performance Design: Built to handle high-frequency use on doors up to 600 lbs., with Rivnuts for added support on lower frequency applications.
Superior Construction and Environmental Compliance
- Durable Aluminum Alloy: Constructed from 6063 T6 aluminum with self-lubricating polyester thrust bearings and a clear anodized finish, it’s made to withstand high-traffic areas.
- Environmentally Friendly: Made from recycled aluminum to meet LEED standards and reduce environmental impact.
Certified Fire Safety and Longevity
- ANSI and BHMA Standards: Certified ANSI/BHMA A156.26-2006 Grade 1 and tested to exceed 25 million cycles, offering exceptional longevity.
- UL Fire Rating: UL-certified for up to 90 minutes on wood doors and up to 3 hours on like-rated doors with a maximum door opening of 4’x10’ for singles and 8’x10’ for pairs.
Specifications
- Sizes: Available in 83”, 85”, 95”, and 120” lengths to fit various door heights.
- Compatibility: Fits 1-3/8” to 1-3/4” doors with options for 2”–2-1/4” thickness using long barrel nuts.
- Tamper-Resistant Installation: Includes TIPIT and Torx security screws for secure and tamper-proof mounting.
- Closers: Conventional overhead surface, concealed sliding arm overhead or floor closers may be used with hinges. Pivot-type floor closers (with a fixed, conflicting center pivot) must be replaced.
Hinge Performance
- The Ligature Resistant Full Surface Geared Hinge has been tested in accordance with ANSI 250.4- 1994 test procedure and acceptance criteria for physical endurance for steel doors and hardware and has surpassed 25,000,000 cycles during testing by an independent laboratory. On a door cycling 400,000 times per year, a hinge will be performing for over 62 years.
- Ligature Resistant Full Surface Geared Hinges are built to handle abuse from high-traffic applications. They are applied to the surface on the edge of the frame and door. No machining or reinforcement is required.
- On conventional hinges, opening and “kick- back” energy concentrate on a few inches of fastened reinforcing plate — with the top hinge handling 100% of the force. Pinless hinges bond the door and frame into an integrated, sag-free unit. “Kick-back” energy dissipates along the entire length of the door and frame. (Compare this to a conventional hinge’s 4-1/2” to 5” at the top of the door and frame).
- The revolutionary Ligature Resistant Full Surface Geared Hinge puts an end to costly and irritating hinge failure problems, the most common cause of entrance failure.
- Ligature Resistant Full Surface Geared Hinges eliminate the gap between the door and frame, providing a weatherproof, rust-proof, tamper- proof barrier. When the door is closed, there are no accessible screws, bolts or pins.
- Ligature Resistant Full Surface Geared Hinges are listed and tested by Underwriters Laboratories to meet the Positive and Negative pressure requirements of UL10B and UL10C, and are in accordance with UBC 7.2 (1997). Ligature Resistant Full Surface Geared Hinges are for use on swinging single fire doors (max. door opening of 4’x10’) or pairs of fire doors (max. door opening of 8’x10’), including double egress, installed in masonry or drywall. Ligature Resistant Full Surface Geared Hinges are rated for up to 1-1/2 hours for wood composite and wood core type fire doors.
