Heavy Duty Pulleys
CMI Heavy Duty Pulleys

Now there's a pulley that's as serious about rescue as you are! We're talking 16,000 pound breaking strength with 5/8" rope capability. The extra large rigging point accepts the largest carabiners--two of them. The extra wide, skirted sideplates fully enclose 5/8" rope, keeping it away from rock or building. Available in 3 or 4 inch sheave diameter, with needle bearings or bushings. Here is a hard core pulley you can stake your life on.
