Rope Type
Yale Ultrex
Ultrex is a 12-strand, single braid comprised of 100
percent Ultra High Molecular Weight Polyethylene (UHMPE) fiber
enhanced with Yale’s Maxijacket HP coating (see next section)
supplying superior abrasion resistance.
Ultrex’s braid angles and twist level are designed to
optimize break strength and keep stretch low. UHMPE is the
most forgiving high modulus fiber, and provides better sheave
cycling capabilities than other high tech fibers.
Ultrex also has zero water absorption, and maintains its
flexibility even in freezing conditions. As is the case for all Yale
ropes, the strengths shown in the following charts are for spliced
ropes, and the splice technique for Ultrex is very easily mastered.
Samson Amsteel
Amsteel is a 12-strand, torque-free single braid that yields the
maximum in strength-to-weight ratio and, size-for-size, is the same
strength as steel-except it is light enough to float. Amsteel Blue is an
excellent wire rope replacement with extremely low stretch, superior flex
fatigue, and wear resistance.
