Set of 6
These can be used with any Reaction Bar product to limit the range of motion of the dynamic weight. Range limiting balls simply consume space. The Pfitz Reaction Bars™ are very powerful, yet they look just like a regular bar bell. In order to control the surprise of the dynamic motion, place 1.188″ diameter hard plastic balls in your Reaction Bar as spacers so that you can remove them as they get used to the dynamic rolling motion of the bars. They are merely a precaution for your safety.
