Harken soft-attach Fly blocks are designed to provide strength without mass, providing sailors and anchor systems with big power in a low-aero package.
Fly blocks are perfect for use on foiling dinghies and sportboats and for vang cascades and backstay systems on Grand-Prix racers, not to mention rigging anchor systems on kayaks!
18 mm blocks feature an integrated stainless steel inner race and rivet, stainless steel ball bearings, and composite fibre-reinforced side plates.
