PORTLAND BRAID

Portland Braid double braided polyester

offers high value at a very competitive price.

Built in the same manner as our Double

Esterlon, Portland Braid offers consistent

performance at an economical price. The

fiber used to produce Portland Braid is

sourced from Yale's qualified suppliers.

As with all of Yale's products, Portland

Braid can be special ordered in ultra-long

continuous lengths.

* 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 the rope'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.

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 265 ft. lbs./lb.

■ Red ultimate 5,929 ft. lbs./lb.

Dielectric Strength: The

maximum allowable leakage

for clean, dry Portland Braid

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.
