Extension springs are normally attached at both ends to other components and when these components move apart, the spring tries to bring them back together again. It is the initial tension that determines how tightly together the spring is coiled. This initial tension can be manipulated to achieve the load requirements of a particular application. Designs normally have hooks, eyes, or other interface geometry at the ends which attach to the opposing components. They are frequently used to provide a return force to components that extend in an actuated position.
