<h3>About Tie Down Engineering</h3><p>Founded in 1969 and headquartered in Atlanta, Georgia, Tie Down Engineering has spent more than five decades earning its reputation as a global leader in custom manufacturing. What started as a focused effort to deliver better-engineered solutions for American industries has grown into a multi-division powerhouse serving markets that range from marine and mobile home to roofing, agriculture, renewable energy, and beyond. Every product Tie Down makes reflects an engineering-first philosophy — and, notably, they're all proudly made in the USA.</p><p>Tie Down operates six specialized manufacturing divisions, each dedicated to a specific market vertical. This structure lets the brand go deep rather than wide, developing purpose-built hardware that holds up under real-world conditions rather than generic components that merely check a box. Whether you're a boat owner, a contractor, or an OEM trailer manufacturer, there's a good chance Tie Down has already engineered the part you need.</p><h3>Trailer &amp; Marine Product Highlights</h3><p>Among the brand's most recognized product lines are its <a href="/6667-tie-down-eng-fender-1380">trailer fenders</a>, which are a staple for boat trailer owners and OEM builders alike. Tie Down offers fenders in galvanized steel, aluminum, and high-impact polyethylene, covering wheel sizes from 8 inches all the way up to 14–15 inches. Their innovative bracket-less plastic fender design mounts directly to the trailer frame without requiring separate fender brackets — a practical solution that simplifies installation and keeps the setup clean. UV-protected finishes on their plastic fenders resist fading, cracking, and degradation over time, making them a smart choice for trailers that see frequent saltwater exposure.</p><p>Equally important for safe trailering are Tie Down's <a href="/6667-tie-down-eng-safety-chains-cables-accessories-200888">safety chains, cables, and accessories</a>. These zinc-plated and galvanized products serve as the critical backup connection between a tow vehicle and its trailer, providing peace of mind in the unlikely event of coupler failure. Tie Down's safety chain lineup spans Class 2 through Class 4 ratings — from 3,500 lb. to well beyond 5,000 lb. carrying capacities — ensuring there's a properly rated option for light boat trailers and heavier-duty towing applications alike. Chains are sold in pairs and come with durable S-hooks for straightforward installation.</p><h3>Why Tie Down Engineering?</h3><ul style="list-style:disc"><li><strong>55+ years of manufacturing experience</strong> rooted in engineering excellence</li><li><strong>American-made products</strong> built with domestic craftsmanship</li><li><strong>Six specialized divisions</strong> serving marine, agricultural, roofing, and other industries</li><li><strong>Broad material selection</strong> — galvanized steel, aluminum, and high-impact polyethylene options</li><li><strong>OEM and aftermarket coverage</strong> for trailer builders and individual owners</li></ul><p>For anyone who trailers a boat, hauls equipment, or maintains a fleet of utility trailers, Tie Down Engineering's catalog represents a reliable, well-engineered choice backed by decades of field-proven performance.</p>
