It measures 1.25 inches wide, 5 inches deep, and 109.25 inches long. The double-hat profile gives the trailer sidewall structural strength, and the post often includes logistic slots for securing cargo straps. It is typically replaced when the original post is bent, severely corroded, or damaged in a collision.
