    Mil. Spec. Extension Springs

    Image of Product. Side1 orientation. Extension Springs. Mil. Spec. Extension Springs.
    These springs are manufactured and tested to strict U.S. military standards for material and construction. All come with a traceable lot number and material test report.
    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.
    Minimum Load—The amount of force required to start extending the spring.
    Maximum Load—The amount of force required to fully extend the spring.
