Low-friction Carbo Air blocks are lightweight, strong, reliable, and affordable. Companions to our popular Harken Big Boat blocks, these small, compact blocks have very high working loads for safe, easy trimming.

The lightweight 57mm Carbo Blocks have a high load capacity and broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, J/24, and catamaran mainsheets.
