The Peterson Bump Hammer Weight Kit helps you adjust the kinetic energy of your hammer to get a perfect strike on your bump key. This high-quality kit consists of two corks and enough lead shot to fill both weight chambers and adjust your natural swing.
Add the lead shots inside the hammer's head and adjust your bump hammer's weight until it matches your natural swing. Once you've succeeded, glue the corks in place.
