Teufelberger EpiCord eye to eye prusiks are a popular friction hitch for professional arborists. This prusik has two sewn spliced eyes, which fit snugly over many carabiners, keeping everything nice and tidy. EpiCord is constructed of a polyester/Technora mix cover, with a Technora/Dyneema blend core. The polyester/Technora cover is very flexible to ensure good knotability. Combined with the high strength of the Technora/Dyneema core, the cord allows your hitch to release when you need it to. 10mm EpiCord works best with 1/2" (12.7-14mm) climbing rope. Made in the U.S.A.
