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.

Sheaves spin on high load ball bearings with fitted races for low friction operatio. 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 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.
