PMI’s Extreme Pro with Unicore Technology static rope is the ultimate polyester kernmantle rope. Its Unicore Technology ensures sheath slippage is nearly eliminated, even when the sheath is entirely cut circumferentially. Typically, when this type of damage occurs, the sheath bunches below the damaged area entrapping the rope technician either above or below the damaged site. The Extreme Pro allows users to pass torn or cut sheath areas whether ascending or descending thanks to the Unicore Technology. This rope is available in multiple lengths and two color options: Coyote/White/Orange, and Green/White/Orange.
