Product features, properties and information

301 Stainless Steel
Mounting hole specifications will be supplied on request. These springs are usually mounted on a drum and the free end attached to a loading force like a counterbalance.
Free ID may vary to meet load specification.
Load capacity can be increased by using multiple strips in tandem, back to back or laminated.
Be sure to leave at least 40mm coiled on the drum at full extension. The spring ID will wrap tightly on the drum so that most applications require no fastening to the drum.

All dimensions on this website are shown in mm unless otherwise indicated.
