Tie Down Engineering: Purpose-Built Fenders & Mounting Hardware

When it comes to protecting your boat or utility trailer from road debris, splash, and the relentless punishment of saltwater environments, few names carry the credibility of Tie Down Engineering. Founded by Chuck MacKarvich in his garage with the simple goal of building practical, reliable solutions for working people, Tie Down has spent over 55 years turning that vision into reality. Their fenders and mounting hardware reflect the same engineering-first philosophy that has defined the company from the start.

A Full Spectrum of Fender Solutions

Tie Down Engineering doesn't take a one-size-fits-all approach to trailer fenders. Their lineup spans multiple materials, profiles, and mounting styles to suit everything from compact jet-ski trailers to larger boat rigs.

• HDPE Plastic Step Fenders: These heavy-duty molded plastic fenders are engineered for durability and a clean, professional look. Designed to fit 8"–12" trailer tires, they feature high-strength HDPE construction that is lightweight yet impact-resistant, offering long-lasting protection against water, sun exposure, and road debris. The UV-stable finish maintains its color and resists fading over time, while the reinforced, ribbed step surface and integrated backing skirt help shield the trailer and cargo from splash, dirt, and gravel.
• SUV-Style Plastic Fenders: Constructed from high-quality plastic, these "SUV" style fenders are designed to be corrosion-proof and impact-resistant. The modular design accommodates 14–15 inch tires and wheels, providing versatility for various trailer setups. Tandem-style versions feature individually molded front and rear sections that seamlessly bolt together without the need for modifications.
• Bracket-Less Plastic Fenders: Tie Down's innovative "Bracket-less" Plastic Fender is specially engineered to mount directly to the frame without the need for fender brackets, providing a seamless and clean appearance. The design makes changing fender position hassle-free, and it accommodates wheels up to 12 inches.
• Galvanized Steel Fenders: Tie Down's Galvanized Metal Fenders are crafted from 16-gauge galvanized steel, offering exceptional strength and corrosion resistance. They can be easily drilled to fit a variety of mounting options, giving installers flexibility to customize for unique trailer requirements.

Matching Mounting Hardware Engineered for Marine Environments

A fender is only as reliable as its mounting system, and Tie Down Engineering ensures both halves of the equation are equally rugged. Their Flush Fender Brackets for boat trailers are galvanized metal brackets that accommodate 8-inch to 12-inch plastic fenders, available in both flush-mount and offset-mount styles for versatility. With their galvanized construction, the brackets are built to withstand the harsh marine environment, offering exceptional durability and corrosion resistance, while providing a sturdy attachment point that keeps fenders securely in place during transportation.

Step Fender Brackets are also available, designed to accommodate large plastic fenders with a perfect fit for tires. Like all Tie Down brackets, the galvanized construction delivers outstanding durability and corrosion resistance in demanding marine conditions.

American-Made Quality You Can Count On

Tie Down fenders are built in the USA to dependable manufacturing standards, providing reliable performance and easy bolt-on installation. Backed by a portfolio of over 95 patents, more than 7,000 products, and ISO 9001:2015 certification, every Tie Down fender and bracket is the product of decades of hands-on engineering experience. Whether you're replacing a worn fender on a fishing boat trailer or upgrading a utility rig for long-haul towing, Tie Down Engineering's fenders and mounting hardware deliver the durability and fitment that serious trailer owners demand.
