CMI 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.
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.
Now there's a pulley that's as serious about rescue as you are!
We're talking 20,000 pound breaking strength with 5/8" (15.875 mm) rope capability. The extra large rigging point accepts the largest carabiners--two of them. The extra wide, skirted sideplates fully enclose 5/8" (15.875 mm) rope, keeping it away from rock or building. Available in 4 inch sheave diameter, with needle bearings or bushings. Here is a hard core pulley you can stake your life on.
