Rope Characteristics

Unitrex XS-8 consists of eight (8) Unitrex ropes plied together to form an 8-strand plaited cable. Very strong, very light and very abrasion resistant, Unitrex XS-8 is unique.

The base cable, Unitrex, is made of parallel strands of Ultra High Molecular Weight Polyethylene (UHMWPE) fiber, bonded together with a rubberized adhesive, wound with rubber tape and over-braided with a polyester jacket, which is saturated with urethane. The subsequent oven curing fuses the tape, making a very tough cable — or, in this case, strands — to make an even larger strength member. Unitrex XS-8 is easily spliced with a straightforward tucking procedure.

* 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.
