Lifeline Gate Eye to Swage – Open Body

The Hayn Lifeline Gate Eye to Swage Open Body is a Type 316 stainless steel all-in-one lifeline assembly that combines a fixed gate eye, a forged bronze open body turnbuckle, and a swage wire terminal in a single fitting, offering the same consolidated hardware count as the closed body version with direct visual access to thread engagement during tensioning. 

Strong Where It Matters

Lifeline Gate Eye to Swage – Open Body

The forged bronze open body resists corrosion while letting riggers confirm thread engagement at both ends without removing the fitting, which matters on a lifeline assembly that sees regular use at the gate but may go long periods without a full inspection. The fixed gate eye provides a clean, permanent connection point for pelican hooks, and the integrated swage terminal eliminates a separate wire end fitting from the assembly. Available in machine swage configuration for imperial wire from 1/8" through 1/4" and metric wire from 4mm through 5mm, with Handy Crimp stud options for 1/8" through 3/16" wire, across open lengths from 9-13/16" to 11-11/16" depending on configuration.

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. 
  • Type 316 stainless steel construction for superior saltwater corrosion resistance
