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 has the required prusik minding capability for use in 3-to-1 Z-system (which means it makes it easier to haul up heavy stuff without popping a vein, or to lower heavy stuff without dropping it!).
A smooth running 1.25" nylon sheave runs on a stainless steel rivet axle, and the color-contrasting aluminum side plates rotate for easy rope insertion and removal. Easy to use, easy to carry - a great palm-sized partner on the mountain and nearly anywhere else!
This pulley is not suitable for use in a tyrolean traverse.
