NOTCH Fusion



The 'tether' has remained the Achilles Heel in the Rope Wrench configuration - until now. For SRT climbers who prefer the friction hitch, the Notch Fusion tether revolutionises the Rope Wrench. Add your existing Rope Wrench, friction cord and a suitable carabiner, and you are good to go - the integrated pulley means no more messing around with multiple components. The Notch Fusion Rope Wrench Tether has a rigid hot-forged aluminium construction to resist twisting or bending, offering significant efficiency improvements on the ascent. With the streamlined and lightweight design, integrated pulley, and more, makes the Notch Fusion the best Rope Wrench Tether on the market! Rope Wrench, Climbing Line, Friction Cord and Carabiner not included.
