Lifeline Toggle Jaw to Swage – Open Body

The Hayn Lifeline Toggle Jaw to Swage Open Body is a Type 316 stainless steel and chromed bronze all-in-one lifeline assembly that combines an articulating toggle jaw stanchion end, a forged bronze open body turnbuckle, and a swage wire terminal in a single fitting for stanchion-mounted lifeline runs. 

Strong Where It Matters

Lifeline Toggle Jaw to Swage – Open Body

This is the open body counterpart to the closed body toggle jaw assembly, offering the same consolidated hardware count and stanchion-mounted angular articulation with the added benefit of direct visual access to thread engagement during dockside tensioning and inspection. The forged bronze open body resists corrosion while eliminating galling concerns at the threaded interface, and the toggle jaw allows the fitting to pivot freely at the stanchion pin to prevent side-loading as the lifeline changes angle underway. 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 9-1/2" to 11-3/8" 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
  • Manufactured in Rocky Hill, Connecticut to Hayn's proprietary tolerances
  • Precision-machined using advanced CNC manufacturing equipment



  • Engineered for seamless integration in marine and architectural rigging systems

  • Short lead times on both standard and custom components

  • Backed by 75 years of marine and architectural hardware expertise
