For over 100 years, W.B. Jones has been providing quality extension springs suited for a variety of application needs. Developed to absorb and hold energy, extension springs also supply resistance to a pulling force. The required tension determines how tightly an extension spring must be coiled. This initial tension can be adjusted to meet the load requirements of a given application.
