Endurance testing on SELECT hinges shows they hold up to decades of heavy traffic.

Our SL11HD concealed, geared continious hinge surpassed more than 25,000,000 cycles in ANSI-approved, physical endurance testing at Architectural Testing, Inc., in St. Paul, Minn. That's 10 times beyond Grade 1 cycle count. The full mortise aluminum hinge was mounted to a standard FRP door to simulate a real-world situation. A piston initiated the door's open/close cycle 16,600 times per day, around the clock. In the real world, an entrance equipped with our hinge, averaging 500,000 cycles per year, would still be performing after 60 years!

What kind of damage did all those test cycles cause? A broken counter. Two worn out door closers. And no measurable change to the hinge.

In addition, a SELECT hinge even stood up to brutal Forced Entry and Ballistic Resistance testing by the U.S. Department of State to earn its highest certification (PDF).


Others claim their hinges are the best. We prove it. Our geared continuous hinges have resisted more brutal testing than any. Read more.
