C. Sherman Johnson 27-408 Interlocking Gate Eyes for 3/16" Lifeline Wire

The C. Sherman Johnson 27-408 Interlocking Gate Eye is a precision-machined marine lifeline fitting designed to create a secure, functional gate opening in your boat's safety lifeline system. Acting as the hinge point of the gate, the interlocking eye on the standing part of the lifeline wire keeps tension in the line and prevents the lifelines from going slack when the gate is open.

This fitting uses a double-threaded design where the stud terminal is threaded into an eye nut, providing a strong and reliable connection at the gate. Loctite should be used during assembly to ensure the stud remains securely seated. The 27-408 is sized for 3/16" wire (measured as the actual wire diameter, not including any vinyl covering).

Key Features:

• Constructed from T-316 stainless steel for maximum strength and marine-grade corrosion resistance
• Double-threaded design — stud terminal threads into eye nut for a secure connection
• Functions as the hinge point at lifeline gate openings, keeping lifelines taut when the gate is open
• Sized for 3/16" lifeline wire (actual wire size, without vinyl cover)
• Assemble with Loctite to ensure secure attachment of stud to eye
• Sold as a pair — includes both interlocking eye components
• Matches the strength of 7x7 or 1x19 stainless steel wire when properly installed

Installation Note: Hand crimp terminals, when properly applied, achieve approximately 65–70% of the breaking strength of 7×7 stainless steel wire. While this is adequate for lifeline applications, these fittings are not recommended for standing rigging or other high-load uses. Always follow the manufacturer's installation instructions for correct results.

C. Sherman Johnson is America's leading manufacturer of stainless steel cable fittings, trusted by sailors worldwide for lifeline hardware, turnbuckles, and rigging components.
