Harken 2603 57mm Double Carbo Airblock With Becket
HARKEN 2603
Double Carbo AirBlock® with Becket - 57mm
Low-friction Carbo AirBlocks® are lightweight, strong, reliable, and affordable.
Carbo AirBlocks® are 60% stronger and 30% lighter than Harken's Classic blocks. The Nylon-resin side plates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Ball bearings, sheave and side plates are UV-stabilized with carbon-black additive 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 57mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, J/24's, and for mainsheet systems on catamarans.
Like all AirBlocks®, the three-way head swivels/locks in front/side positions. Blocks are easily disassembled with a single Allen® wrench.
