Harken 57mm Swivel 5 Sheave Carbo Airblock

Harken Carbo AirBlocks® are 60% stronger and 30% lighter than Harken Classic Blocks. The nylon resin sideplates are densely packed with long glass fibers for a compact block with a high strength-to-weight ratio. Ball bearings, sheave and sideplates are UV stabilized with carbon black for maximum protection.

The high load 57mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, and J/24s, and for mainsheet systems on catamarans.
