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.

Flat Disc Springs
These flat rubber springs handle heavy loads, similar to Belleville disc springs, and resist oxidation, oil, and abrasion.
When stacking, separate springs with rigid flat washers. The washers must be large enough to cover the entire surface of the springs.
Deflection is the distance a spring compresses under load.

Corrosion-Resistant Die Springs
A quieter, more vibration-resistant alternative to traditional steel die springs, these polyurethane springs resist oxidation, oil, and abrasion in high-load, high-pressure applications.
Deflection is the distance the spring compresses, expressed as a percentage of its length.
As you squeeze a die spring, it gets harder to push. Spring rate is the amount of force required for every inch of compression. The higher the spring rate, the harder it is to compress the spring.
