Abstract

A fender having an arcuate section and integral steps is mounted to a trailer frame. The fender arcuate section has a recessed pad. The steps are reinforced with ribs. A pair of fender brackets each having a horizontal center plate are secured to the trailer frame using bolts. The fender step ribs are placed on the fender bracket center plates and fastened thereto from under the fender brackets in a manner that hides the fasteners from normal view. The fender steps have cutouts that receive the bolts. The trailer spring hangers are sandwiched between the trailer frame and the fender brackets in a manner that enables the spring hangers and the fender brackets to be adjustably positioned on the trailer frame independently of each other.
