Cobalt Blue Polypropylene Rope is the strongest synthetic rope in its class because of our extremely tight tolerances from fiber extrusion to the finished rope. The result is a rope of unsurpassed quality and consistency. These unique characteristics make it a hands down choice for an industry that demands a highly superior product.

  • Approximately 40% stronger than standard polypropylene rope
  • 18% elongation
  • Superior abrasion resistance
  • Excellent UV resistance
  • No loss of strength when wet
  • Resists rot and mildew
