    Double-Loop End

    The farther you stretch these springs, the harder they pull to bring the two ends back together. They're commonly used to tension cable, return an air cylinder to its starting point, or hold a door closed.
    Loop End—The most secure attachment method. With fully closed loops, there's no risk of slipping off.
    Double-Loop End—Ends are strengthened by an extra loop, so these springs are less likely to break if overstretched.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Corrosion-Resistant 302 Stainless Steel—Won’t corrode from exposure to moisture and mild chemicals, including ammonia often found in cleaning solutions. These springs are easier to extend than steel, but can’t handle as high a load.
    Minimum Load—The amount of force required to start extending the spring.
    Maximum Load—The amount of force required to fully extend the spring.
