This 6" heavy duty spring helps eliminate noise and stress on mounts and stands, and increases longevity of hanging chains, heavy bag straps, and swivels. It also helps eliminate vibrations. Great for all types of punching bags and it hols up 350lbs.

    Spring is built like a tank. I can foresee years of use. Shipping was excellent with delivery within just days.
