Polydyne™ is a high strength double-braided rope incorporating a polyester sleeve over a nylon core. Despite the dissimilar stretch characteristics of these fibers, Polydyne™ maximizes load sharing between core and sleeve, yielding extremely high strength and high working energy absorption capacity. Available with Maxijacket Coating.

Double Esterlon™ is a double-braided rope made from unique, high tenacity, cordage-finish, polyester yarn. Yale’s exceptionally high strengths come from: selecting this specific yarn (minimum 9.2 gpd), careful attention to machine setup and the extraordinary lubricity of the yarn. Double Esterlon™ offers low stretch, high strength, excellent wear life and dielectric strength.
