Stainless Steel Tension Spring
An extension spring’s ends attach between two mechanisms. The extension springs hooks and loops store and absorb energy. Through hooks or loops, an extension custom made spring provides return force to connected mechanisms.

Tightly wound extension springs typically sit in the no-load position. More stress in the end hooks—as opposed to the spring body—limits the performance of extension springs.
