The unique construction of Arbor-Plex wraps tough polyester jacket fibers around polyolefin center fibers creating a lightweight, high-strength rope with maximum resistance to wear and fiber fusing. Arbor-Plex uses a proprietary construction to tighten the braid and keep the rope round and firm for knot control and snag resistance. Arbor-Plex was the first synthetic rope designed specifically for the arborist industry and remains one of the best values in climbing lines today. Available in 120', 150', and 600' lengths.
