About Tie Down Engineering
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.
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.
Trailer & Marine Product Highlights
Among the brand's most recognized product lines are its trailer fenders, 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.
Equally important for safe trailering are Tie Down's safety chains, cables, and accessories. 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.
