## Description

The lightweight CRx has a stainless-steel axle and lightweight nylon sheave to maximize efficiency and provide the best strength to weight ratio. Ideal for alpine climbers, mountaineers, or anybody who wants a lightweight utility pulley at a great price point. The CRx's compact size and featherweight belies its solid strength and efficiency; it is stronger than any other pulley in the same size and price range. The side plates are prusik minding for use in a 3 to1 Z haul system. 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 on ziplines, cables or high-speed use.

Compact size fits in pocket or in backpack so that it is always handy for quick access in an emergency. Wide base design has been proven to work efficiently with Prusik cords of up to 8mm. Solid side plates help prevent foreign object access and reduce snags. Side plates are rounded and rotate for easy and secure placement at any point along the rope.

Review: Great size - Great pulley that fits very well into my swift water PFD. I also carry two more in my class 3 harness. Simple to use as expected. Well constructed and accommodation of most size carabiners. They are lightweight and compact which make adding them to your kit seamless.
Review: Simple and cheap - Works as advertised, and is by far the cheapest rescue pulley option on the market. Hook a carabiner through both plates and you're good to go.

### ⭐⭐⭐⭐⭐ Simple and cheap

Works as advertised, and is by far the cheapest rescue pulley option on the market. Hook a carabiner through both plates and you're good to go.

### ⭐⭐⭐⭐⭐ Perfect for Crevasse Rescue
*by J***N on April 22, 2021*

This is my second pulley, I liked the first one so much. The best feature is the “wings” that tend to your prusik knot. This is very useful as a progress capture in a hauling system. Considering it weighs so little, it’s a great piece of kit that lets me leave my ascender at home and travel fast and light on the mountain. The hole is large enough to fit all of my carabiners as well.
