30 meter pre-cut, spliced hank. Arrow Frog is Yale's 11.7 mm lightweight arborist climbing line made from premium grade 24-strand polyester. The perfect balance between the weight of an 11mm line and the 'feel' of a 13mm rope. Kernmantle construction (two ropes in one) - Yale Arrow Frog keeps its round shape even under heavy loads especially when up close to the anchor point if you are using a pulley-based saver. Great feel in the hand and excellent for knot-tying. Able to be spliced. Designed by Yale Cordage for use with mechanical descenders, split tail techniques or friction hitch set-ups. Sets a new standard in climbing rope technology.
