Low-friction Carbo Air blocks are lightweight, strong, reliable—and affordable. Companions to the popular Harken Black Magic block line, these small, compact blocks have very high working loads for safe, easy trimming.
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.
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.
