    Straight-Wire with Double-Loop

    End × Straight-Wire 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—Ends are strengthened by an extra loop, so these springs are less likely to break if overstretched.
    Straight-Wire End—Bend the long, straight ends into custom loops and hooks.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Minimum Load—The amount of force required to start extending the spring.
    Maximum Load—The amount of force required to fully extend the spring.
