Harken 75mm Carbo Single Swivel Block with Becket

Harken 2660 Carbo AirBlock has a single 2-15/16 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 75 mm Carbo has a safe working load of 1200 lbs (550 kg). It releases easily under load and is perfect for mainsheet systems on sport boats like the Melges 24, J/105 and Henderson 30.
