Low-friction Carbo AirBlocks®
are lightweight, strong, reliable—and affordable. Companions to the
popular Harken® Black Magic® 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
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.
