    Extension Springs with Swivel-Hook Ends

    Image of Product. Front orientation. Extension Springs. Extension Springs with Swivel-Hook Ends.
    Put an end to downtime from broken hooks. The swivel-hook ends rotate freely from the spring body to handle stress and twisting without snapping.
    Hook End—Hook into closed holes, such as hanger bolt eyes. These springs work best when kept under tension, as they're more likely to slip off than loop-end springs when tension is released. Also known as machine hook ends.
    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.
