Durabel Extension Springs

Extension springs are used to provide return force to components. They can be implemented in many applications such as automotive assemblies, garage door springs, tools, and toys. (read more)

EXTENSION SPRINGS are attached at both ends to other components. When these components move apart, the spring tries to bring them together again. Extension springs absorb and store energy as well as create a resistance to a pulling force. It is initial tension that determines how tightly together an extension spring is coiled. (read more)

Extension springs, often referred to as 'pull springs', are primarily used to retract a load from its extended position; they can be applied to opening or closing a mechanism. Century Spring Corp.

Associated Spring Raymond garter springs are engineered and manufacturer to provide a consistent and reliable product. They feature high initial tension to provide constant load and a special tapered end to assure a strong connection and a continuous near uniform body diameter. (read more)

The constant-force spring is will suited to long extensions with no load build-up. In use, the spring is usually mounted with the ID tightly wrapped on a drum and the free end attached to the loading force, such as in a counterbalance application. (read more)

Swivel Spring Anchors allow for the adjustment of tension on the extension spring - without twisting the spring. The attachment point to the extension spring is designed to swivel, allowing the spring to be drawn tighter (or looser) without twisting the spring. (read more)

All SPEC stock helical extension springs have uniform body diameter and are produced with full twist loops the same diameter as the body. They are wound with initial tension; some force is required before coils are initially separated. As with other Associated Spring stock components, they are capable of wide application for experimental, development, prototype and maintenance work. (read more)
