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-stable for maximum protection. High-strength, tilting lead blocks with clamps are used for halyard control on smaller keelboats and as "head knockers" on dinghies and beach cats for direct sheet guidance from the boom. The hole spacing and rivet size match those of the Classic versions, making upgrades easy. The clamp is reversible for upward or downward clamping. Uses: mainsail/jib sheets, fine trimming, mainsheet control lines, downhauls, Cunningham, leech tensioners.
