High tenacity polypropylene webbing combines with innovative and patented roller technology in the high strength Zamark 5 body, utilizing a stainless steel shaft and marine grade brass roller to eliminate the frictional losses of traditional cam straps, resulting in 10x the holding force in a strap that is super easy to use. An integrated hook and loop containment strap ensures neat storage when not in use, eliminating the coiled viper pit of tangle associated with other straps. Technically superior and simple to use, these straps are available in either 6’, 9’ or 12’ lengths. Blue.
