57mm Carbo Blocks
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.
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.
