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. A length of Spectra® line with a polyester cover is included. Spectra is a registered trademark of Honeywell International, Inc.

Harken 29mm T2 Soft-Attach Double Block 2147

2147

€64.95

Tax included. Shipping calculated at checkout.

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 29, 40, and 57 mm blocks feature composite sheaves that spin freely on Delrin® ball bearings with curved bearing races. They have no metal shackles or rivets, making them the lightest soft-attach blocks Harken has ever designed. 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. Delrin® is a registered trademark of E. I. du Pont de Nemours and Company or its affiliates. Spectra® is a registered trademark of Honeywell International, Inc.
