Single Action Spring Hinges

Single acting door spring hinges (door swings one way) are used when you need a door to close automatically. We offer single action spring hinges in sizes from 3-1/2 inches up to 7 inches so you’ll be able to find exactly what you need no matter your application. Choose from hinges made from steel or stainless steel. We also have UL fire rated single action hinges for commercial applications.
