Strengthen and protect your tandem trailer with this heavy-duty steel fender backing plate, designed to reinforce the fender area while shielding your trailer from water, road debris, and mud. Built from durable 16-gauge rolled steel, this backing plate provides long-lasting structural support for tandem trailer fenders and helps protect cargo and trailer components during everyday hauling.

Installed behind the fender, the backing plate acts as a protective barrier that prevents debris from being thrown into the trailer bed or onto cargo. It also adds rigidity to the fender mounting area, helping reduce vibration and wear during heavy use.

This backing plate is commonly used on tandem axle utility trailers, equipment trailers, landscape trailers, and cargo trailers. It ships unfinished, allowing trailer owners and builders to paint or coat it to match their trailer frame or apply rust protection before installation.

For best results, this backing plate is typically welded to the trailer frame or fender structure, creating a strong, permanent installation capable of withstanding rough roads and heavy loads.
