Polydyne / High Strength Double Braided Rope

Polydyne

Polydyne does virtually everything Double Esterlon does, but allows you to drop bigger wood, increasing productivity. Polydyne has a much higher working energy absorption meaning you can do more to the rope without damaging it.

The cover of this double braid is identical to our Double Esterlon, right down to the tree grade Maxijacket coating, the toughest in the industry. The secret is all in the core which in the case of Polydyne is high tenacity tire grade nylon.

Nylon provides the energy absorption advantage and allows the rope to stretch more in its early load cycle.

Even if you use Double Esterlon for rigging line consider Polydyne deadeyes; as they  dynamically load a very short length of rope.

** Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of line's rated working load constitutes hazardous shock load and would void normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and safe use of rope. Polydyne is made to Yale Cordage Specification #YCI-PD-012
