RA/SMC Stainless Steel Pulleys - Single or Double, NFPA Certified |
|
Based on Russ Anderson's original design, these pulleys are essential equipment for the serious rigger. Rotating side plates allow attachment of the pulley anywhere on the rope and the 3" and 4" models will accept multiple carabiners. Axle nuts are marked with a blue witness line to indicate if the axle nut has been turned or tampered with.
