SMC/RA Pulleys - 4" x 5/8" NFPA Ball Bearing

Based on Russ Anderson’s original design, the SMC/RA Pulleys are essential equipment for the serious rigger. These pulleys feature rotating side plates that allow attachment anywhere on the rope, and the 3” and 4” models can accommodate multiple carabiners. The axle nuts are marked with a blue witness line to indicate if they have been tampered with or turned.

Features
