Harken soft-attach Fly Blocks are designed to provide strength without mass, providing sailors with big power in a low-aero package. Designed specifically for high-tech lines, these efficient Blokks have an incredible working load for their small size. Fly Blokks are perfect for use on foiling dinghies and sportboats and for vang cascades and backstay systems on Grand-Prix racers.
18 mm Blokks feature an integrated stainless steel inner race and rivet, stainless steel ball bearings, and composite fiber-reinforced side plates.
Use the 2161 "tight cinching" 18 mm in applications where the Blokk needs to be secured extremely close to the deck.
A length of Spectra® line with a polyester cover is included.
