    Cut-to-Length Compression Springs

    Always be ready for the perfect fit. These springs are extra long to cut a custom length whenever you need it. Their open ends make cutting easier but prevent them from standing on their own. You’ll need to install them in a hole or over a shaft, or grind the ends flat.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Spring Rate—To determine the spring rate of a cut spring, first multiply the spring rate given by the spring's original length, then divide the result by the cut length (in inches).

    Extension Springs

    Image of Product. Front orientation. Extension Springs. Loop End.

    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.
    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.
