Ordering extension spring with turnable loops online

Extension springs with normal loops or hooks should only be used for up to 60% of the permitted tension, as the loop or the hook of the spring is weaker than the rest of the spring. In order to be able to use the spring to its maximum, without running the risk of loop breaks, you can instead use this series of extension springs with hardened loops, which have tapered ends.
