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.

Stainless steel side plates place the CMI High Line Pulley a cut above the rest. Large diameter aluminum sheave allows a knotted 1/2" rope to pass with ease. The sheave can be locked off to make a full strength tie off with the quick pin supplied. The large center hole is used to support the load and will accept up to 2 carabiners. The two small holes can be used for tag line attachments.
