Harken's Carbo AirBlocks are 30% lighter with 60% higher working loads than Harken's Classic blocks. These small, compact blocks have very high working loads for safe, easy trimming no matter how hard the wind blows.
The 40mm blocks are perfect for the main and jib sheet systems on high-performance dinghies.
Their sideplates are constructed of lightweight, UV-stabilized, Nylon resin that has been reinforced with densely packed fibers.
The Carbo AirBlocks have grooved races, which gives these small blocks greater load capacity.
All Carbo AirBlocks feature Cam-Lock or U-Lock locking systems to hold the shackle in front or side positions, or allow them to swivel to prevent sheets and lines from twisting.
