Form exercise band into a loop and secure loop by clamping the band Klip over the two ends of the band, a few inches from each end. This device allows band to be formed into a loop without tying the band into a knot. Many exercises with resistive exercise band require users to form band into a loop in order to perform the exercise. This Klip is 3.5" long, which is slightly smaller than the standard Klip which is 5.5" long. The smaller size makes the Klip less bulky.
