Harken 57mm Carbo Single Swivel Block with Becket

Harken's Single Carbo AirBlock 2601 has a 2-1/4 inch diameter sheave, a becket for line attachment and a shackle that swivels to prevent line twist. Carbo AirBlocks are 60 percent stronger and 30 percent lighter than Harken Classic blocks.

High-load 57 mm 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.
