This 5/16 in. (8mm) diameter by 30-inch long Bee-Line eye and eye cord is long-lasting and high performing. Yale Cordage's technora/poly cover provides excellent heat resistance. It features two sewn tight eyes for carabiner use professionally stitched by the experts at Rope Logic. Eye to eye tails are used to create what tree climbing instructors call a "closed system" resulting in a finished friction hitch with both ends attached to the connector instead of one hanging loose, as with the traditional hitch or single-eye slit tail. The eye-to-eye tail also allows use of several hitches that are easily learned and extremely smooth performing. By utilizing both ends of the type of split tail friction is more evenly distributed resulting in more consistent friction through a knot that is less binding, yet grabs quite firmly. The system is enhanced significantly when incorporating a micropulley that fair-leads the hitch for one handed slack tending. Bee Line has high heat and abrasion resistance. Tensile strength: 5,400 lbs.
