HOW TO BUY  

Double Esterlon

Double Esterlon is a double-braided rope constructed of high- tenacity 1W81 polyester fiber, which has a unique cordage finish. This yarn, with an average strength of 9.2 grams per denier, along with Yale’s careful attention to converting machinery setup and the yarn’s extraordinary lubricity, yields the highest-strength double-braid polyester available.

Double Esterlon has low stretch, high diaelectric strength, and excellent wear life. It is completely spliceable, delivering the cataloged strengths when spliced properly. It is identified by two green strands braided into the cover structure and is available with optional Maxijacket urethane coating to further enhance the rope’s wear resistance.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower the maximum working load.
** Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of the rope’s rated working load constitute hazardous shock load and would void the normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.

 

Green working 291 ft. lbs./lb.

Specific Gravity: 1.14

Dielectric Strength: The maximum allowable leakage for clean, dry Double Esterlon is 100 micro-amperes when tested at 100kV per Yale Method 712-1701 Rev 1 “Routine Production Test.” Absorbed and entrained moisture or impurities will increase rope’s conductivity dramatically.
