Product Overview
Harken 40mm Carbo Air Double Block with becket for a highload 4:1 or 5:1 purchasing system. Low-friction Carbo AirBlocks are lightweight, strong, reliable and economical. Consistently 30% lighter and 60% stronger than equivalent Classic blocks. The sideplates are UV-stabilized, high-strength resin and designed for small-diameter lines favored by racers. Good for jib and mainsheet systems on high-performance dinghies, and for high-load control lines on small keelboats. Recipient of both the Dame Award and Sail Magazine s Freeman-Pittman Award for innovation, this innovative line of blocks turns fiber-reinforced composite construction into a reliable strength-to-weight ratio you can depend on. Companions to the popular Harken Black Magic block line, these small, compact blocks work well with very high working loads for easy trimming.
