The Harken Carbo Air blocks are 60% stronger and 30% lighter than their Classic blocks. Use the 40 mm Carbo block for jib and mainsheet systems on high-performance dinghies and for loaded control lines on small keelboats.
The nylon-resin sideplates are densely packed with long-glass fibres for a compact block with a high strength-to-weight ratio. Sheaves spin on high-load ball bearings with fitted races for low-friction operation. Ball bearings, sheave, and sideplates are UV-stabilized for maximum protection.
Use for:
- Main/jib sheets
- Mainsheet fine-tune
- Control lines
- Vangs
- Cunninghams
- Outhauls
