Ultrex is a 12-strand single braid of Ultra High Molecular Weight Polyethylene (UHMWPE) fiber from DSM Protective Materials and enhanced with Yale’s Maxijacket High Performance coating, which supplies superior abrasion resistance. Ultrex's braid angles and twist level are designed to optimize break strength and keep stretch low.
Sierra 78 is a 12-strand single braid of bio-based Dyneema®, an Eco Sustainable fiber. Made with bio-based feedstock, this fiber maintains the unique properties of Dyneema® while providing a more sustainable solution without compromising final product performance. Yale is excited to be one of the first to partner with DSM Protective Materials on this commitment to realize a more sustainable product. Choose Sierra 78 for exceptional performance and a certified green product for your equipment.
Maxibraid Plus is a double-braided rope constructed of an inner load-bearing core of Ultra High Weight Molecular Polyethylene (UHMWPE). The polyester outer sleeve is slightly thicker than Ultrex Plus, which would provide more abrasion resistance in high-wear applications.
Ultrex Plus is a double braid constructed of an inner load baring core of Ultra High Molecular Weight Polyethylene (UHMWPE), treated with Maxijacket coating for enhanced toughness. Sleeved with high-tenacity polyester, Ultrex Plus is spliceable, using 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.
