The Stainless Steel Construction is completely ideal for boat trailers because the fender is lightweight, durable, and will not rust! The 16 Gauge Stainless Steel finish also provides a unique and stylish look for your boat or enclosed trailer. These are commonly seen protecting 13 inch to 15 inch trailer tires. Typically replacing a boat trailer fender means a tire blew out or the old fender rusted through. Keep in mind when doing this project you may need additional hardware to complete the installation. The mirror like finish of these stainless fenders is sure to give your trailer that extra something. If you are currently running Aluminum Wheels on your trailer, these fenders would be the perfect complement to your rig. Kick rust and oxidation to the curb, and mount a set of fenders to your trailer that are worry free.
