60 meter pre-cut, spliced hank. Yale's 11.7 mm lightweight arborist 24-strand polyester climbing line. 0.7mm larger diameter than Blaze for improved hand control but does not impede the use of mechanical devices. Excellent handling characteristics and easy to see in the tree - designed for use with advanced climbing tools and techniques as well as traditional methods. Kernmantle construction (two ropes in one) - Yale Blue Tongue keeps its round shape even under heavy loads and close to the anchor. Great feel in the hand and excellent for knot-tying. Able to be spliced. Designed by Yale Cordage for use with mechanical descenders as well as self-belaying split tail techniques. Popular with competition climbers. CE Approved to EN1891A.
