Lifeline Gate Eye to Swage – Closed Body

The Hayn Lifeline Gate Eye to Swage Closed Body is a Type 316 stainless steel all-in-one lifeline assembly that combines a fixed gate eye, a closed tubular body turnbuckle, and a swage wire terminal in a single fitting for stanchion gate installations.

Strong Where It Matters

Lifeline Gate Eye to Swage – Closed Body

The gate eye end provides a fixed loop connection point for pelican hooks and gate fittings, while the closed tubular body protects the threaded tensioning mechanism from the marine environment and the integrated swage terminal eliminates a separate wire end fitting from the assembly. Consolidating these three components reduces the total hardware count at the gate end of the lifeline run, simplifying both initial installation and subsequent inspection. 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 12-3/8" 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
