Heavy Bag Spring
The heavy bag spring will absorb some of the force of the impact when the bag is hit. With the heavy bag spring installed, the impact from your strikes is absorbed by the spring reducing the shock to your joints. Wear to your equipment and noise is reduced.
Hang the heavy bag using the supplied spring and clip. It is best to use a swivel with the heavy bag spring when possible.
Recommended for heavy bags up to 150 pounds.
