Made of stainless steel, these springs are more corrosion resistant than steel extension springs. All have drawbars to prevent overextending, which can cause failure.

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.
