This Prusik with Steel Clip is a 1/2" XTC Plus around a steel core for extra safety and durability, with a strong steel clip. These wire-core prusiks had been tough to find, and our Canadian climbers had requested them for years. Yale Cordage stepped up to the plate to manufacture these unique wire-core prusiks which provide the utility of a hip-prusik with the security of the steel cable in side the 16-strand cover.
