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 line, these efficient blocks have an incredible working load for their small size. Fly blocks are perfect for use on foiling dinghies and sportboats and for vang cascades and backstay systems on Grand-Prix racers.

18 mm blocks feature an integrated stainless steel inner race and rivet, stainless steel ball bearings, and composite fiber-reinforced sideplates. Doubles feature composite line guides that are integrated into the block head. They keep the block aligned correctly by pushing the lashing line to the outer edges of the block's head.

T2 blocks come in single and double configurations and can be tied, spliced, or lashed to almost anything. T2 doubles feature composite line guides that are integrated into the block head. They prevent the block from capsizing by pushing the lashing line to the outer edges of the sideplates. The 18 mm block features stainless steel ball bearings and an integrated stainless inner race and rivet for optimal strength-to-weight.

All T2 blocks route the attachment line through the block head and sheave, decreasing the loads on the sideplates and acting as a safety backup for the system. Use for traveler controls, mainsheets and vangs, cascades, bridles, and other systems where small lightweight blocks are called for.

A length of Spectra® line is included.
