Lifeline Deck Toggle to Swage – Closed Body

The Hayn Lifeline Deck Toggle to Swage Closed Body is a Type 316 stainless steel all-in-one lifeline tensioning assembly that combines a two-hole deck mount toggle jaw, a closed tubular body turnbuckle, and a swage wire terminal in a single fitting. 

Strong Where It Matters

Lifeline Deck Toggle to Swage – Closed Body

Combining the deck toggle, turnbuckle body, and swage terminal into one assembly reduces hardware count and eliminates multiple connection points from the lifeline run, simplifying both installation and long-term inspection. The closed tubular body protects the threaded adjustment mechanism from the marine environment, and the deck toggle jaw allows angular movement at the mounting point to prevent side-loading as the lifeline tension and angle change 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 9-3/16" 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
  • 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
