Hayn Rod Rigging Insulator

The Hayn Rod Rigging Insulator is a backstay insulator manufactured by Petersen Stainless in the UK and distributed by Hayn, designed to break electrical continuity through rod rigging systems across NAVTEC rod sizes from -08 through -30. 

Strong Where It Matters

Rod Rigging Insulator

Backstay insulators are required on any sailboat using the backstay as an antenna ground plane, and the rod rigging version must handle the same high loads as the rod itself while maintaining electrical isolation between the upper and lower sections. Manufactured by Petersen Stainless to the same production standards as the Hi-MOD compression fitting line, each insulator ships with the corresponding rod cap part number included, eliminating a separate ordering step. Available in seven configurations covering rod sizes from -08 through -30 with thread sizes from 1/2-20 through 7/8-14 and hardware factors from 9-3/4" through 14-7/8". When ordering by NAVTEC part number, specify the rod dash size to ensure the correct rod cap is included.

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
