Harken's Carbo AirBlocks® are 60% stronger and 30% lighter than Classic blocks.  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 are UV-stablized for maximum protection.

Companions to the popular Harken® Black Magic® line, these small, compact blocks have very high working loads for safe, easy trimming. Use for jib and mainsheet systems on high-performance dinghies and for loaded control lines on small keelboats.  Other common uses are mainsheet fine-tune, vangs, cunninghams, and outhauls.
