Low-friction Carbo AirBlocks®
are lightweight, strong, reliable—and affordable. Companions to the
popular Harken® Black Magic® line, these small, compact blocks have very
high working loads for safe, easy trimming.
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.
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-stabilized with carbon black for maximum protection.
