These ISC pulleys are also NFPA compliant. Aluminium side plates with silicone impregnated bushings on the sheave for a very smooth, effortless action. Axles are riveted rather than bolted to comply with European standards. Tamperproof and impossible to unscrew during use. Compatible with all ISC steel rigging carabiners.
