Extra-Stretch Extension Springs
These fabric-covered rubber springs stretch up to three times their original length—much farther than traditional extension springs, tie downs, and shock cords. All have carabiner ends with spring-loaded latch openings. Do not use to hold overhead loads.
As you stretch an extension spring, it gets harder to pull. Minimum load is the amount of force required to start to extend the spring. Maximum load is the amount of force required to fully extend the spring. Spring rate is the amount of force required for every inch of extension.
