Rope Characteristics

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. Portland Braid can be special ordered in ultra-long continuous lengths. We also offer our 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 maximum working load.
** Working load is based on static or moderately dyanmic lifting/pulling operations. Instantaneous changes in load, up or down, in excess or 10% of the rope’s related 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.

Rope Details

Fiber Type: Polyester Core, Polyester Sleeve
Elongation at WL: 2.0%
Elongation at Ult Break: 12.3 – 14.1%
Specific Gravity: 1.38 g/ccc
Dielectric Strength: The maximum allowable leakage for clean, dry Portland Braid 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.

Rope Benefits

Low stretch
Great wear life
Easily spliced
Built in the same manner as our Double Esterlon, this product offers consistent performance

Elastic Elongation

The coloured area under the curve represents the rope’s energy absorption capability.
