Lifeline Gate Eyes

Hayn Lifeline Gate Eyes are Type 316 stainless steel threaded end fittings available in single eye and interlocking eye configurations, designed to thread directly into lifeline adjuster and turnbuckle bodies to provide a fixed connection point for pelican hooks and gate hardware. 

Strong Where It Matters

Lifeline Gate Eyes

The single eye configuration provides a standard fixed loop end for pelican hook attachment, while the interlocking eye design allows two gate eyes to connect directly to each other — eliminating the need for a separate shackle or connector at the gate interface. All three thread sizes use left hand thread (1/4-28, 5/16-24, and 3/8-24) for correct engagement with Hayn lifeline adjuster and turnbuckle bodies. Manufactured from Type 316 stainless steel throughout, with a consistent eye depth of 31/32" and eye width of 11/16" across all single eye 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.
