Abstract:
The disclosure relates to a load bearing, post-free sidewall for an over-the-road trailer or the like. A bottom rail of the sidewall is attached to the floor of the trailer and secures the sidewall thereto. Each of the sidewalls comprises a pair of substantially parallel, vertically extending, horizontally spaced and load bearing plastic panels having foam insulation disposed therebetween. The bottom rail member transfers loads thereon substantially equally to each of the panels of each sidewall.
