Extension Springs with Loop Ends
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. Rate is the amount of force required for every inch or millimeter of extension.

Corrosion-Resistant Extension Springs with Loop Ends
Made of stainless steel, these springs are more corrosion resistant than steel springs. They're also easier to extend than steel springs. 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. Rate is the amount of force required for every inch or millimeter of extension.
302 stainless steel springs have good corrosion resistance.
316 stainless steel springs have excellent corrosion resistance.
