SELECT aluminum geared continuous hinges provide the longest-lasting solution for high-traffic doors. As a result, they save materials and energy. Our hinges have been proven to withstand 25 million cycles — equal to more than 50 years of use on the average high-traffic door. A longer life cycle means fewer hinges used, which means fewer resources used, fewer emissions produced and fewer tons of waste.
