The CMI Trolley is a simple design for use on 3/8" or 1/2" cable. Dual hardened sheaves turn on sealed ball bearings for a smooth, wobble-free ride. Perfect for ziplines and other ropes course uses. Oversized stainless steel sideplates extend well beyond the sheaves to protect them from hard usage. A rear slot allows a steel carabiner to surround the cable, allowing redundancy from the cable to the harness.
