Carbo Airblocks are 60% stronger and 30% lighter than our Classic blocks.

The nylon resin side-plates are densely packed with long glass fibers for a compact block with a high strength to weight ratio.

Sheaves spin on high load ball bearings with fitted races for low friction operation. Ball bearings, sheave, and side-plates 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 57mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightenings, Dragons, Solings and J/24s and for mainsheet systems on catamarans.
