Use this adjustment sleeve and two connector tubes to create a rigid spreader bar. This sleeve is 16 inches in length. There are six different settings, spaced at two inch intervals. A swivel eye at the center provides a strong connection point for rope or chain. When used with two 12 inch connector tubes the spreader bar provides a range of 28 to 36 inches. This combination when used with your "Click" cuffs provides a rigid spreader bar. In the "Other Items" category you will find a spreader bar with swivel eyes for traditional cuffs. All pieces are interchangeable.
