Yale Ultrex Single Braid Line
YALE Ultrex 12 strand single braid (UHMWPE) Winch Line
Stronger than steel, floats on water.
Ultrex is a 12-strand single braid of Ultra High Molecular Weight Polyethylene (UHMWPE) fiber enhanced with Yale's Maxijacket High Performance coating, which supplies superior abrasion resistance. Additional abrasion resistance is attributed to the larger filament diameter. In comparable yarn sizes Ultrex will contain roughly half as many individual filaments compared to similar products. Each of these individual filaments are more cut resistant than the finer filaments in other products and manifest improved abrasion resistance in the larger rope product. Ultrex's braid angles and twist level are designed to optimize break strength and keep stretch low.
UHMWPE is the most forgiving high-modulus fiber, giving better sheave-cycling capabilities than other high-tech fibers. Ultrex has zero water absorption and maintains its flexibility even in freezing conditions. As is the case for most Yale ropes, the strengths shown in the charts are for spliced ropes.
Available per metre in 10mm, 12.5mm and 16mm.

(A common mistake for people first starting with this splice procedure is to skip Step 2. For Ultrex you ADD 2 full fids to the original mark made in step 1.)
ELECTRICAL UTILITY: Light weight, high strength, low stretch, ideal for lead lines used in heavy pulling operations.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower 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 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.
