Lifeline Toggle Jaw

Hayn Lifeline Toggle Jaws are Type 316 stainless steel swage terminal fittings with an integrated articulating jaw end that mounts directly to a stanchion pin, allowing the lifeline to pivot freely at the attachment point and prevent side-loading at the wire terminal. 

Strong Where It Matters

Lifeline Toggle Jaw

The toggle jaw is the correct fitting for any stanchion connection where the lifeline enters at an angle rather than perfectly in line with the pin axis, which covers the majority of real-world installations. Without articulation at the stanchion end, the wire terminal experiences continuous side-loading that accelerates fatigue failure over time. Available in machine swage and Handy Crimp configurations for imperial wire from 1/8" through 1/4" and metric wire from 4mm through 5mm, with pin diameters from 1/4" through 3/8" across six imperial and two metric configurations.

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
