The high load 75mm Carbo has a broad working range.

Low-friction Carbo AirBlocks from Harken are lightweight, strong, reliable and affordable.

These compact single swivel blocks have very high working loads for safe and easy trimming no matter how hard the wind blows.

Side plates 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.
