    Tech Info

    Product Description

    Carbo AirBlocks® are 60% stronger and 30% lighter than our Classic blocks.

    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 systems to lock the shackle in front or side positions, or swivel to keep line from twisting.

    The high-load 57 mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, and J/24s, and for mainsheet systems on catamarans.

    Use for:

    Main/jib sheets, Mainsheet fine-tune, Control lines, Vangs, Cunninghams and Outhauls.
