Harken 40mm Carbo Blocks

Harken 40mm Carbo Blocks
Carbo AirBlocks are 60% stronger and 30% lighter than our classic blocks. Use the 40 mm Carbo 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 fibers 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 UV stabilized with black additive for maximum protection.

Use for:


  • Main/jib sheets

  • Mainsheet fine-tune

  • Control lines

  • Vangs

  • Cunninghams

  • Outhauls
