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 UV stabilized with black additive 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 75 mm Carbo has a safe working load of 1200 lbs (500 kg). It releases easily under load and is perfect for mainsheet systems on sport boats like the Melges 24, J/105 and Henderson 30.
