Based in Portage, Mich., Select Products Ltd. has announced its SELECT 85-inch SL27 HD continuous geared hinge has passed the U.S. Department of State (DOS) tests for high-security applications and is now DOS-approved for use in State Department entrances.

"Our hinge has exceeded 12 million cycles so far in independent durability tests, so we were confident it could also resist aggressive assaults," said Bob Cronk, SELECT national sales manager. "The top-to-bottom, frame-to-door contact and 50-plus fasteners withstand abuse better than the three to four contact points and 32 screws of a butt hinge."

According to the company's announcement, testing included forced entry and ballistic resistance of Structural Systems tests (SD-STD-01.01). The testing was done at White Laboratory Inc. in Street, Md., and was part of required strength testing of DOS building entrance systems, which is a precautionary measure to protect American embassy personnel. The hinges earned the DOS' largest protection level, 60 minutes.

U.S. Bulletproofing manufactured the door on which the hinge was mounted.
