Aoneky 100Lb 250Lb Professional Spring Review

Hold punching bags as heavy as 250 pounds, all steel construction. This is a professional spring, designed for heavy bags over 100lb. The spring helps absorbs the vibrations so the bag hanger doesn't shake with each hit. This is a HEAVY duty spring, recommend for 100-250lbs bag, there will have no stretch if the bag is two light. It can be installed from the top mount or from top of the heavy bag and bottom part of the chain.
