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.


The high-load 57mm Carbo has a broad working range. Use for main and jib sheets on centerboard and small keelboats, and for mainsheet systems on catamarans.  Other uses include mainsheet fine-tune, control lines, vangs, cunninghams, and outhauls.


Swivel blocks can lock in two directions or spin freely to avoid lines twisting. Reversible cam arms.
