Product Description

J24 Harken 57mm Double Swivel Carbo Block

Carbo AirBlocks are 60% stronger and 30% lighter than the classic Harken block. 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. The high-load 57mm Carbo has a broad working range.

Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, J/24s, and for mainsheet systems on catamarans.
