C. Sherman Johnson

<h3>About C. Sherman Johnson Co., Inc.</h3><p>Few names carry as much weight in the world of marine rigging as <strong>C. Sherman Johnson</strong>. Founded in 1958 by Curtiss S. Johnson Jr., the company began with a sailor's passion and a single brilliant invention. As the story goes, Johnson designed the original Handy Lock Turnbuckle as a side project, and after years of part-time marketing, the product's reception was strong enough that he left a career in engineering management to build a full line of stainless steel marine fittings. That leap of faith paid off — today, C. Sherman Johnson is widely recognized as America's #1 manufacturer of stainless steel cable fittings for marine and architectural applications.</p><p>From its East Haddam, Connecticut base, the company has remained family-owned and operated across multiple generations. What started with a focus on the marine industry eventually expanded in the 1980s into architectural hardware for cable railing systems. Today, C. Sherman Johnson's products can be found everywhere from offshore sailboats racing under ISAF rules to commercial architectural installations and even U.S. Military applications.</p><h3>What Sets C. Sherman Johnson Apart</h3><p>The defining characteristic of C. Sherman Johnson hardware is its uncompromising commitment to American manufacturing and material quality. Every marine product is made in the USA from marine-grade Type 316 stainless steel — a grade specifically chosen for its superior corrosion resistance in saltwater environments. This dedication to domestic production allows the company to maintain tight quality control and deliver consistent performance in demanding conditions, season after season.</p><p>Their <a href="/7279-c-sherman-johnson-turnbuckles-201115">turnbuckles</a> are the foundation of the product line and remain the industry benchmark for sailboat rigging. Whether tensioning standing rigging on a blue-water cruiser or fine-tuning a dinghy's shrouds, C. Sherman Johnson offers configurations to match virtually any application — tubular, open-body, jaw, hook, and welded eye styles across a wide range of thread sizes. Complementing the rigging lineup are <a href="/7279-c-sherman-johnson-eye-straps-pad-eyes-200385">eye straps and pad eyes</a>, including their popular hinged pad eye designs that provide secure and versatile attachment points throughout the boat.</p><p>Onboard organization and safety depend on more than just rigging. C. Sherman Johnson's broader hardware parts and accessories catalog covers clevis pins, cotter rings, link plates, gate eyes, grab rail components, fender cleats, and more — the small but essential pieces that hold a well-rigged boat together. Boaters who work with Dyneema or synthetic lifelines will also appreciate the brand's purpose-built <a href="/7279-c-sherman-johnson-tapes-201053">rigging tapes</a>, including their mast boot tape designed to protect lines and fittings from the elements.</p><p>Rounding out the lineup, C. Sherman Johnson also produces <a href="/7279-c-sherman-johnson-anchor-accessories-200089">anchor accessories</a> and related marine fittings that address the practical challenges of anchoring and docking. Whether you're outfitting a new build or upgrading aging hardware on an existing vessel, the breadth and depth of the C. Sherman Johnson catalog makes it a go-to resource for serious sailors and powerboaters alike.</p><h3>Trusted by Designers, Builders, and Owners</h3><p>C. Sherman Johnson hardware has earned the trust of OEM sailboat manufacturers, professional riggers, and recreational boaters for more than six decades. The company's continuing ability to design, manufacture, and distribute products that hold up in the harshest marine environments has cemented their reputation as the industry's number-one supplier of lifeline fittings. For anyone who takes their time on the water seriously, C. Sherman Johnson represents hardware you can count on.</p>

Product Details

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.
