Tie Down Engineering: Precision-Built Trailer Parts & Accessories

When it comes to keeping your trailer road-ready and your cargo secure, few names carry the weight of Tie Down Engineering. Founded in 1969 and headquartered in Atlanta, GA, Tie Down Engineering has grown into one of America's most respected manufacturers of trailer components — backed by over 55 years of engineering experience, more than 95 patents, and ISO 9001:2015 certification. Their trailer parts and accessories reflect that depth of expertise at every level, from hardware and brackets to full roller systems.

A Full Spectrum of Trailer Components

Tie Down Engineering's trailer parts lineup is remarkably comprehensive. Whether you're trailering a boat, jet ski, ATV, or utility load, the brand supplies the critical components needed to keep your rig performing safely. Their catalog spans bunk components, guide-ons, rollers and roller accessories, hitch components, fenders, spare tire carriers, winch stand components, U-bolts, and safety chains — meaning it's possible to source nearly everything from a single manufacturer known for consistent quality and fit.

One standout area is their roller system lineup, which includes bow rollers, keel rollers and pads, side rollers, wobble rollers, and roller brackets — essential for smooth, damage-free boat launches and retrievals. Their guide-on systems are equally well-developed, with PVC post guide-ons available in 48" and 60" lengths in both 90-degree and 13-degree slant configurations, as well as aluminum saltwater guide posts engineered for maximum corrosion resistance in harsh marine environments.

Engineering That Stands Up to the Elements

A defining characteristic of Tie Down Engineering's trailer accessories is their attention to corrosion resistance — a non-negotiable quality for anyone trailering in saltwater or wet conditions. Their Bolster Brackets, for example, are crafted with hot-dip galvanized steel and feature non-slip dimples for increased load stability and precise vertical adjustment. Fender brackets carry galvanized construction as well, and their innovative "bracket-less" plastic fenders mount directly to the trailer frame without requiring separate fender brackets — simplifying installation and position adjustments. Hardware throughout their lineup, including bolts and nuts, is zinc-plated, while mounting brackets are galvanized for long-term protection.

Tie Down Engineering also produces components designed to work with standard industry sizes and mounting patterns, making it straightforward to integrate their parts into existing trailer setups or OEM builds without custom modifications.

Trusted by Builders and DIY Enthusiasts Alike

Tie Down Engineering's manufacturing capabilities — including CNC cutting, robotic welding, injection molding, and powder coating — are all handled in-house across their 825,000-square-foot Atlanta facility. This vertically integrated approach means tighter quality control and consistent part dimensions from one production run to the next. The result is a brand that professional trailer builders and hands-on DIY owners both trust to deliver components that perform under real-world towing demands.
