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 26-412 is a closed-body tubular lifeline turnbuckle featuring a toggle jaw on one end and a hand crimp terminal on the other, sized for 1/8" wire. Designed for sailboat lifeline systems, this turnbuckle installs at the bow or stern rail to tension the longest run of lifeline wire. The streamlined tubular body eliminates exposed threads and snag points, keeping lines and sails clear of cotter pins and sharp edges.

The toggle jaw end provides an increased range of articulation compared to a fixed jaw, accommodating slight misalignment between fittings during tensioning and under load. Locking is achieved with check nuts on either side of the turnbuckle body, removing the need for cotter pins entirely. The center cross-hole allows easy tension adjustment by hand or with a marlinspike.

The hand crimp threaded terminal is constructed from 316 stainless steel and is matched to 1/8" wire diameter. When properly installed using appropriate hand crimping tools, a hand crimp fitting achieves approximately 65–70% of the breaking strength of 7x7 stainless steel wire — adequate for lifeline applications. This fitting is intended for lifeline use only and should not be used for standing rigging or other high-load applications.

Key Features:

  • Full 316 stainless steel construction for excellent strength and marine corrosion resistance
  • Closed tubular body — no exposed threads, no snag points for lines or sails
  • Toggle jaw end for increased range of motion and alignment flexibility
  • Check nut locking system — no cotter pins required
  • 3" of adjustment (take-up) for precise lifeline tensioning
  • 1/4"-28 thread size
  • Open length: 11-1/2"; Closed length: 8-1/2"
  • Working load limit: 500 lbs
  • Hand crimp terminal sized for 1/8" wire — DIY-friendly installation with proper hand crimping tools
  • Clevis pin secured with cotter ring

The C. Sherman Johnson 26-412 is one of the brand's most popular lifeline turnbuckles, offering a clean, professional finish with reliable performance for smaller sailboats. All stainless steel construction ensures long-term durability in both freshwater and coastal saltwater environments.
