Pulleys & Trolleys

We began making pulleys quite simply, with the introduction of just four 2 3/8" rescue pulleys to the market in 1982. They quickly became known the world over for their strength, durability and flexibility. Fueled by demand, today our pulley line has grown to over 50 models, each designed with a specific use in mind. Whether you need a pulley for casual top-roping or long hauls, everyday confined space entry or "film at 11" rescues, or any of the variety of applications created by the blossoming ropes course industry, CMI has a pulley designed with your exact need and requirements in mind.

Learn more about how our pulleys are made and the advantages and disadvantages of each type of component on our Pulley Education Page.
