Carbo AirBlocks are 60% stronger and 30% lighter than the classic Harken block. Use the 40mm Carbo for the 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. Best for main/jib sheets, mainsheet fine-tune, control lines, vangs, cunninghams, outhauls.
