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.

Wear-Resistant 1095 Spring Steel Sheets and Strips
- Yield Strength: Not Rated
- Hardness: Rockwell C50 (Very Hard)
1095 spring steel has a higher carbon content than 1075 spring steel for better wear resistance. It is often fabricated into parts that will be used under continual stress, such as spring clips and washers. This material is also known as blue-tempered steel.
