Carbo pulley 40 mm triple with swivel. Carbo airblocks® pulleys are 60% more resistant and 30% lighter than our conventional pulleys. 40 mm carbo can be used for the production of jib and mains lines on High-performance dingers and for high load adjustment bumps on small blords. The composite cheeks of resin-tnylon are reinforced by long glass fibers allowing the realization of a compact poulie with a high resistance/weight ratio. The reasons rotate on high -resistant ball bearings with adjusted paths for a minimum friction coefficient. The ball bearings, the reas and the cheeks are treated black carbon for a resistance greater UV.
