High-capacity security hinges rated for loads up to 1,800 kg per hinge.
Blast, ballistic, and forced entry threats place unique demands on door hardware. The Surelock McGill HT10 and HT12 are mortice-fitted, high-capacity hinges designed to support these demanding security applications.
The HT10 and HT12 share performance characteristics and are available with a 10 mm (HT10) or 12 mm (HT12) leaf thickness. When installed using approved stainless steel screws, each hinge provides a radial load capacity of 500 kg.
Grade 316 stainless steel construction provides corrosion resistance in demanding environments. The HT10 and HT12 have been tested to 1,500,000 cycles on a 500 kg doorset and are designed for long-term service on heavy security doors.
Thrust and needle roller bearings support smooth operation under high loads. Concealed grease fittings provide convenient maintenance access without compromising the hinges’ appearance.
When installed using M12 stainless steel (A2) screws, the HT hinges provide:
• Radial load capacity of 500 kg per hinge
• Thrust load capacity of 1,800 kg per hinge
The HT10 and HT12 are part of a broader portfolio of hinge solutions for demanding applications. In addition to standard products, Surelock McGill designs and manufactures bespoke hinges tailored to specific project requirements. Our hinges are used across government, critical national infrastructure, heavy industry, and heritage sectors.
