Harken 57mm Soft-Attach Double Block 2153

The Harken 57mm Soft-Attach Double Block 2153 is a lightweight, high-performance sailing block designed for efficient rope handling in dinghy racing, keelboats, yachts, and performance sailing systems. Engineered with Harken’s innovative soft-attach design, this marine pulley block eliminates the need for metal shackles or rivets, reducing overall weight while maintaining exceptional strength and reliability.

This 57mm Soft-Attach Double Block from Harken can be tied, spliced, or lashed to almost anything, making it an extremely versatile solution for modern rigging systems. The T2 range of double boat blocks features integrated composite line guides within the block head, helping to position the lashing line towards the outer edges of the side plates to prevent the block from capsizing during use.

Built with durable composite sheaves running on low-friction Delrin® ball bearings and curved bearing races, the Harken T2 Double Block delivers smooth, efficient operation under load. The soft-attach system routes the attachment line through the block head and sheave, reducing stress on the side plates while also providing an integrated safety backup.

Ideal for traveller controls, mainsheets, vangs, cascades, bridles, and other lightweight control systems, the Harken 2153 Double Block is designed for sailors who demand high performance, reduced weight, and dependable load handling in demanding marine environments.
