Swage Shroud Terminals

 Hayn Swage Shroud Terminals deliver the precise fit and long-term corrosion resistance that standing rigging demands. Machined from Type 316 stainless steel and available in a full range of imperial and metric wire sizes. 
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.

Strong Where It Matters

Swage Shroud Terminals

Shroud terminals are among the most load-critical connections on any sailboat rig, and Hayn has been manufacturing them to exacting tolerances since 1950. Each terminal is swaged from Type 316 stainless steel, creating a permanent, high-strength bond with the wire that eliminates the fitting-interface movement that drives long-term fatigue failure.
