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.

Use the 2161 "tight cinching" 18 mm in applications where the block needs to be secured extremely close to the deck.

T2 blocks come in single and double configurations and can be tied, spliced, or lashed to almost anything. 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 are lashed or spliced through the load-bearing center of the block, decreasing the loads on the sideplates and acting as a safety backup for the system.

Use the 2161 light cinching 18 mm in applications where the block needs to be secured extremely close to the deck.

A length of Spectra® line with a polyester cover is included.
