Tie Down Engineering: Over 55 Years of American-Made Innovation
When Chuck MacKarvich started Tie Down in his Atlanta, Georgia garage in 1969, his goal was straightforward: build practical, reliable solutions for working people. More than five decades later, that founding spirit still drives every product the company engineers. Today, Tie Down has grown into one of America's largest family-owned manufacturers, with over 95 patents, a catalog of 7,000+ products, and ISO 9001:2015 certification — all produced right here in the USA.
Tie Down's reach spans a remarkable range of industries, from marine and roofing to manufactured housing, agriculture, safety, and renewable energy. What unifies every division is a commitment to engineering-first design, precision manufacturing, and domestic production. The company's Atlanta facilities cover over 500,000 square feet and are equipped with state-of-the-art CNC sheet and tube cutting, robotic welding, injection molding, and tool-and-die capabilities — technology Tie Down was among the first in the Southeast to adopt as far back as the early 1980s.
Trailer & Marine Products Built to Work Hard
For trailer builders, boat owners, and marine enthusiasts, Tie Down Engineering is a go-to source for components that hold up under real-world demands. Their Fenders & Mounting Hardware lineup is a cornerstone of their trailer offering, featuring UV-protected plastic fenders and galvanized steel mounting brackets engineered to resist corrosion in even the harshest marine environments. Paired with these are their standalone Fenders — including innovative bracket-less designs that mount directly to the trailer frame for a clean, professional appearance without extra hardware.
Reliable hitching starts with dependable connection points, and Tie Down's Couplers, Pins & Accessories deliver exactly that. Whether you're securing a boat trailer, utility trailer, or recreational hauler, these components are precision-manufactured to meet standard industry sizing and mounting patterns, making them straightforward to integrate into both new builds and upgrades. Rounding out the trailer ecosystem, Tie Down's broader Trailer Parts & Accessories selection covers safety cables, quick links, chain, and more of the hardware that keeps trailers road-ready and compliant.
Tie Down's marine division extends well beyond the trailer itself. Their Dock Steps — including the NautiSteps aluminum ladder series — bring the same engineering discipline to waterfront access, offering spring-assisted designs, non-slip polypropylene treads, corrosion-resistant aluminum construction, and a 3-year warranty. It's the kind of product that reflects Tie Down's broader philosophy: every solution, from a simple fender bracket to a dock ladder, should be built to outlast the conditions it faces.
