Harken 40mm Carbo Cheek Block

Harken 2644 single cheeck Carbo block mounts flat in plane with decks for changing angles on control lines. Size is appropriate for jib and mainsheet systems on high-performance dighies and for loaded control lines on small keelboats.

Small 40mm Carbo AirBlocks have 1-9/16 inch diameter sheaves. The shackle swivels to prevent line twist. AirBlocks are 60 percent stronger and 30 percent lighter than Harken Classic blocks.

Use for mainsheets, jibsheets, mainsheet fine tune, control lines, vangs, cunninghams and outhauls.
