Toggle Jaw and Closed Body

The Hayn Toggle Jaw and Closed Body turnbuckle pairs an articulating toggle jaw with a Type 316 stainless steel tubular body, providing angular freedom at the chainplate end and a protected threaded tensioning mechanism in a single assembly covering wire diameters from 3/32" through 1/2". 

Strong Where It Matters

Toggle Jaw and Closed Body

The toggle jaw end articulates freely to prevent side-loading as the rig moves under load, while the closed tubular body shields the threaded adjustment mechanism from the marine environment, reducing long-term maintenance requirements compared to an open body design. Available in six configurations with pin diameters from 1/4" through 3/4", open lengths from 7-1/2" through 17-11/16", and wire diameter compatibility from 3/32" through 1/2", the range covers the full span of standing rigging wire sizes common in production and performance sailboats. The part number system keys directly to the toggle pin size, making cross-referencing to existing hardware straightforward.

Engineered In America Every Hayn fitting is designed and manufactured at our facility in Rocky Hill, Connecticut — the same American workmanship that has set the standard for stainless steel rigging hardware since 1950.
Cold-Worked Production Hayn fittings are cold-worked, not cast. That distinction matters: the cold-working process refines grain structure, increases fatigue resistance, and produces a fundamentally stronger component — one built to perform when the load comes on it.
Precision Manufacturing Our Rocky Hill production floor runs CNC vertical mills, CNC lathes, large-capacity mill-turn centers, and waterjet cutting systems — all configured to produce hardware that meets exact specifications, every time.
75+ Years of Excellence Hayn has been engineering and manufacturing marine and architectural rigging hardware since 1950. That track record isn't just history, it's the design knowledge, failure data, and continuous improvement that goes into every product we make.
