Description
Approved by the New York City Housing Authority (NYCHA) and patented in Taiwan, China and the USA. The foolproof locking device for these double acting spring hinges meets U.S. Federal specification FF-HH-116C (the top button on the hinge is not removable, so that the spring cannot be removed or tampered with). This makes these hinges particularly ideal for use on homes, commercial projects and public buildings. Click here if you need assistance measuring a Double Action Hinge.
