Markar HG315 Hinge Guard Continuous Hinge | Stainless Steel Full Mortise
The Markar HG315 is an industrial-grade stainless steel pin and barrel continuous hinge featuring a unique, integrated edge guard. This full mortise hardware is a premier solution for door restoration in high-security and high-traffic institutional environments. By wrapping the door edge, the HG315 prevents foreign objects from being wedged between the door and frame while distributing the door's weight across the entire length of the jamb—effectively eliminating sagging and frame stress.
Enhanced Safety and Lead-Lined Compatibility
The HG315 is specifically engineered for specialized commercial applications where door protection and safety are paramount:
- Anti-Tamper Edge Guard: The guard design prevents objects from being placed in the hinge gap, serving as a vital solution for commercial door security and a safety measure in behavioral health or childcare settings.
- Center Hung Lead-Lined Support: Ideally suited for center hung lead-lined doors, providing the structural support necessary for the extreme weight of radiation-shielded openings.
- Concealed Fasteners: All mounting hardware is hidden when the door is closed, preventing unauthorized tampering and maintaining clean architectural lines.
- No Reinforcement Required: When installed on a 16 gauge or heavier metal frame, additional hinge reinforcements are not necessary, simplifying the installation process.
Robust Performance and Fire Safety
Built to endure the rigors of high-abuse environments, the Markar HG315 is a durable solution for door edge reinforcement:
- 600 lb. Weight Capacity: Expertly supports heavy doors up to 600 lbs. and 4'0" in width, ensuring a smooth, "no-fail" operation over millions of cycles.
- 304 Stainless Steel: Constructed from high-quality stainless steel with stainless steel end pins for maximum corrosion resistance.
- Grade 1 Certified: Meets ANSI/BHMA A156.26 Grade 1 standards for structural integrity and life-safety compliance.
- 3-Hour Fire Rating: Fully classified under UL 10C for positive pressure, making it suitable for any fire-rated opening.
