The RIT 8 mm Eye and Eye is made from the high performing, heat resistant RIT 500 cord. It has a firmer, tight Aramid sheath for superior durability and is non-glazing. Extensively field tested by professional arborists, the RIT 8 mm Eye and Eye provides even and consistent friction in a wide variety of hitches. These hitch cords feature CNC sewn eyes on each end. The sewn eyes are every bit as strong as a hand spliced eye, but we can offer them at a lower price. For a consumable item such at this, the lower priced sewn eyes make a lot of sense for many climbers.
