Roundslings have exceptional strength while being comparatively light weight. The designs of the slings are unique, a single or double sleeved jacket surrounds the inner construction of polyester yarn wrapped in a continuous and circular fashion. They are suitable for picking up loads that need to be gripped tightly while being lifted, rather than a flat surface, the round body of roundsling can grip odd loads because of the multi-wrap design of the internal fibers. The unique material nature of roundsling resists rotting and mildew caused by moisture. Material: 100% high tenacity polyester multifilament, polyamide, polypropylene(cover and core yarn).
