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.
Carbo AirBlocks® are 60% stronger and 30% lighter than Harken's classic series, designed especially for the racer looking for higher strength to lower weight ratios. Use for main/jib sheets, mainsheet fine-tuning, control lines, vangs, cunninghams, outhauls, etc.
