Carbo AirBlocks® are 60% stronger and 30% lighter than our 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. Blocks feature Cam-Lock or U-Lock locking systems to lock the shackle in front or side positions, or swivel to keep line from twisting.
The high-load 57 mm 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.
