Sterling Rope's 11mm arborist line TriTech makes this safety flipline made by SherrillTree highly abrasion resistant. TriTech™, an 11mm rope designed with Sterling's unique Technora™ sheath, Dyneema™ inner jacket and nylon cores. By combining the abrasion resistant sheath over a high strength inner jacket and pliable core, they have created a rope that is strong and durable, yet still supple enough to move and position easily. TriTech™ may provide additional resistance to incidental nicks and offers the most abrasion resistance with non-conductive properties. 8 foot Flipline and Grizzly Spliced eyes on each end.
