    Constant-Force Strip Springs

    Image of Product. Front orientation. Strip Springs. Constant-Force Strip Springs.
    No matter how far you extend them, these springs pull back with the same amount of force. Compact and tightly coiled, these springs extend to multiple times their length to pull objects in a linear direction. All are stainless steel for corrosion resistance. Please allow for 1 ½ coils on the shaft at full extension to hold the spring in place.
