SMC CRx Pulley


SMC CRx Pulley

The SMC Crevasse Rescue X Pulley is designed specifically for use as an alpine emergency device and no alpinist or back country skier/boarder should ever be without rope and a self-rescue pulley. Should the CRX Pulley be put into action, its diminutive size and light weight will be in contrast to its solid strength and efficiency when used in 2-to-1 systems.

The CRX Pulley tests to greater strengths than other pulleys in the same range of size and price. It has the Prusik minding capability required for use in 3-to-1 Z-systems, making it easier to haul up heavy stuff without popping a vein, or to lower heavy stuff without dropping it!

A smooth running 1.2" nylon sheave runs on a zinc-coated axle, and the color-contrasting aluminum side plates rotate for easy rope insertion and removal. Easy to carry and easy to use - a great palm-sized partner on the mountain and nearly anywhere else! Intended for use with rope up to a maximum size of 1/2".
