Carbo Fiddles
The lightweight, high-strength composite plastic used in the sideplates, sheave, and balls makes Carbo AirBlocks 30% lighter and 60% stronger than Harken classic blocks. Use with small-diameter, high-tech lines on high-performance dinghies, small keelboats, and catamarans. The 40 mm blocks handle loads similar to Harken 2.25” (57 mm) blocks, and the 57 mm blocks can take loads similar to 3.00” blocks.
