The eye sling is perhaps the most versatile tether for rigging hardware, this one is made with 19mm Samson Tenex 12-Strand Single Braid, Sling-Grade Polyester, 20 ft. in length. A block, Portawrap or other device is secured within the sling's eye, and a choking hitch such as a cow hitch or timber hitch is tied using the running end. Although one must know knots to use an eye sling, there's no arguing its efficient simplicity. This ropes construction is stronger and more flexible than others because of its loosely woven, hollow construction. Since there is no core to this rope, abrasion wear is distributed throughout the cordage where it can be more easily monitored. 22,000 pound tensile strength, 2,200 pound WLL, weighs 4.1 pounds.
