Harken Carbo Single Pulley 40Mm

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.

Carbo AirBlocks® are 60% stronger and 30% lighter than our Classic blocks. Use the 40mm Carbo for boom and mainsheet systems on high performance boats and for loaded control lines on small keelboats.

The resin-coated nylon side plates are densely packed with long glass fibres for a compact block with a high strength-to-weight ratio. Sheaves rotate on high load ball bearings with cupboard races for low friction operation. Ball bearings, sheave, pulley, and side plates are UV with carbon black for maximum protection.
