Harken 57mm Carbo Block
Low-friction Carbo AirBlocks from Harken are lightweight, strong, reliable and affordable. These compact Ti-Lite blocks are extremely versatile allowing partial swivelling and the easy addition of a becket where required.
Sideplates of high strength resin are UV stabilised to provide excellent protection against long term exposure to saltwater and sun. Carbo AirBlocks are 60% stronger and 30% lighter than our classic blocks making them perfect for the smaller diameter lines favoured by racers.
The high load 57mm Carbo has a broad working range. Use for main and jibsheets on centreboard and keelboat like lighnings, dragons, solings and j24's and for mainsheet systems on catamarans.
