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 heavily loaded control lines on small keelboats. The nylon resin side plates are densely packed with long glass fibers, resulting in a compact block with a high strength-to-weight ratio. The sheaves rotate on high-load ball bearings with bearing shells designed for low-friction operation. The ball bearings, sheave, and side plates are UV-stabilized for maximum protection. High-strength, tilting lead blocks with cleats are used for halyard control on smaller keelboats and as "head knockers" on dinghies and beach cats for direct sheet control from the boom. The hole spacing and rivet size match those of the Classic versions, making upgrades easy. The cleat is reversible for upward or downward cleating. Applications: mainsheet/jib sheet, fine trimming, mainsheet, control lines, downhauls, Cunningham, leech tensioner.
