Eye Toggle Jaw and Closed Body

The Hayn Eye Toggle Jaw and Closed Body turnbuckle pairs a fixed bolt eye on one end with an articulating toggle jaw on the other in a Type 316 stainless steel tubular body, covering wire diameters from 3/32" through 5/8" across 16 standard configurations with standard and extended jaw depth options on most sizes. 

Strong Where It Matters

Eye Toggle Jaw and Closed Body

The fixed eye end connects to a chainplate bolt while the toggle jaw end articulates freely to prevent side-loading at the opposite connection point, making this the correct configuration where one end of the assembly requires bolt attachment and the other needs angular freedom. The closed tubular body protects the threaded tensioning mechanism from the marine environment, and extended jaw depth options (-X, -XX, and -XXX suffixes) are available on most sizes for installations where standard clearance is insufficient. Available in 16 configurations covering thread sizes from 1/4-28 through 1-12 and pin diameters from 1/4" through 1", with open lengths from 7-7/16" through 1'11-3/4" spanning the full range of wire sizes from 3/32" through 5/8".

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
