40mm Harken Carbo Cheek Block

The Harken 40 mm Carbo cheek block mounts flat on the deck, boom or mast and turns lines with low friction. Harken designs the 40 mm Carbo for jib and mainsheet systems on high-performance dinghies and for highly loaded control lines on small keelboats. According to Harken, Carbo AirBlocks® are 60% stronger and 30% lighter than its Classic blocks.
