Revolutionizing Ligature Resistance in Hinge Design
The DH430 Concealed Geared Continuous Hinge offers advanced ligature resistance, providing a tamper-proof barrier that fully closes the gap between door and frame. Key benefits include:
- Integrated Ligature Resistance: Built with a completely concealed design to eliminate ligature points, rust-proof and tamper-proof.
- Heavy-Duty Performance: Tested for high-frequency use, it can withstand doors up to 600 lbs with reinforced Rivnuts, dissipating energy along the entire hinge length to prevent wear.

Durable and Environmentally Friendly Construction
