Ultrex Plus / UMHPE Core Polyester Sleeve Rope

Ultrex Plus

Ultrex Plus™ is a double braid of Ultra High Molecular Weight Polyethylene, treated with Maxijacket coating for enhanced toughness. Sleeved with high tenacity polyester, Ultrex Plus is spliceable utilizing conventional high modulus splice techniques, or the new Yale tuck splice, which shortens the bury portion and minimizes the length of the larger diameter associated with a bury type splice. All strengths shown are for spliced line.

* 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.
