Description
Low-friction Carbo Air blocks are lightweight, strong, reliable—and affordable. Companions to the popular Harken Black Magic block line, these small, compact blocks have very high working loads for safe, easy trimming.
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. Carbo blocks are perfect for the small-diameter hard lines favored by racers. Carbo AirBlocks® are 60% stronger and 30% lighter than Harken's classic blocks. Use the 40 mm Carbo for jib and mainsheet systems on high-performance dinghies and for loaded control lines on small keelboats.
Use for: Main/jib sheets, Mainsheet fine-tune, Control lines,Kickers, and Cunninghams.
