This rugged chain adapter can be used with any pair of grip handles (round, pinch, hub style, etc.) for grip training during sled dragging, cable rowing, etc. You might as well get some grip training in during a sled dragging session or upper back work! Two such handles are required; one for each hand. The HANDLES ARE NOT INCLUDED and must be purchased separately (a pair of 2 inch pinch grip handles is shown attached to the chain adapter in the photographs for illustrative purposes only). Three clips are needed in total; only a single clip is included with the adapter because each handle is also sold with it's own included clip, for a total of the three needed clips.
