Harken 57mm Carbo AirBlocks
Max Line Diameter = 10mm
Carbo AirBlocks are 60% stronger and 30% lighter than Harkens's classic blocks. The nylon resin sideplates are densley packed with long-glass fibres for a compact block with a high strength-to-weight ratio.
The high-load 57mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, J/24s and for mainsheets systems on catamarans.
