The 2.25" (57 mm) is the original Harken block. They are compact and lightweight, with fast trim and release under high or low loads. Use for main or jib sheets, shippaker halyards or control lines on dinghies, scows, beachcats and iceboats, as well as small offshore racers and cruisers.
These blocks feature removable beckets to allow easy attachment of pre-spliced line, a set screw that locks the shackle in front or side positions or allows it to swivel freely, free rolling Delrin ball bearings, and UV-stabilized sheave and sideplates.
