This full featured pulley has contrasting anodized aluminum side plates, stainless steel axle and lightweight Nylon Sheave to maximize efficiency and provide the best strength to weight ratio. Ideal for alpine
climbers and mountaineers who want the lightest strongest pulley available at an exceptional price point. The CRx's
diminutive size and featherweight belies its solid strength and efficiency when used in 2-to-1 C-system tests to
greater strengths than any other pulleys in the same range of size and price. It also has the required prusik minding
capability for use in 3-to-1 Z-system.
