Product Description

J24 Harken 40mm Fixed Carbo Block

Carbo AirBlocks are 60% stronger and 30% lighter than the classic Harken block. Use the 40mm Carbo for the 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 UV stabilized with black additive for maximum protection.
