Harken Carbo Blocks 57mm


Harken Carbo AirBlocks

Harken Carbo AirBlocks are 60% stronger and 30% lighter than the Classic Blocks. The high-load Harken 57 mm Carbo Block has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, and J24s and for mainsheet systems on catamarans.

The nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection.

Blocks feature Cam-Lock or U-Lock locking system to lock the shackle in front or side position, or swivle to keep line from twisting.
