Harken soft-attach Fly blocks are designed to provide strength without mass, offering sailors significant power in a low-aero package. These efficient blocks are engineered specifically for high-tech line and deliver an incredible working load relative to their small size. They are ideal for use on foiling dinghies, sportboats, vang cascades, and backstay systems on Grand-Prix racers.
Construction: The 18 mm blocks feature an integrated stainless steel inner race and rivet, stainless steel ball bearings, and composite fiber-reinforced sideplates.
Low Profile: Use the 2161 “tight cinching” 18 mm model in applications where the block needs to be secured extremely close to the deck.
Included Line: A length of Spectra line with a polyester cover is included with the block.
