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 yarns
extraordinary lubricity, yields the highest
strength double braid polyester available.
Double Esterlon has low stretch, high
strength, excellent wear life, dielectric strength
and 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 ropes wear resistance.

* Knots and abrupt bends significantly reduce the strength of all ropes and lowers 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 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. Double Esterlon is made to Yale Cordage Specification #YCI-DE-022.

Energy Absorption
The colored area under the curve represents
the rope's ability to do "work" and is expressed
in foot-pounds per pound of rope in tension.
■ Green working 291 ft. lbs./lb.
■ Red ultimate 7,711 ft. lbs./lb.
Dielectric Strength: The maximum allowable
leakage for clean, dry Double Esterlon is 100
Micro Amperes when tested at 90KV per ASTM
1701-05 "Routine Production Test". Absorbed
and entrained moisture or impurities will
increase ropes conductivity dramatically.
