This is the strongest multi-part sling with great flexibility. It will develop its full strength on small pins with a D/d ratio of 1/1 where D is the pin and d is the sling body. (4/1 D/d when comparing the pin to the component parts.) For heavy lifting
work this is the most efficient wire rope sling that meets all of the standards. The eyes have the wire ropes (12) laid in parallel so that there is no cross over and then they are wrapped with heavy duty material to keep them in position. This sling was developed to meet conditions specified by the
US Navy and the Wire Rope Technical Board Sling Manual. Testing has proven it to be the strongest multi-part wire rope sling when attached to small pins because it has twelve parts of wire rope in the loop in a parallel construction.
