BTM. RAIL GD

Bottom rails are the lower structural beams that run along the sides of the trailer, connecting the side walls to the floor structure and providing a mounting surface for the landing gear and crossmembers. They are commonly replaced when damaged from repeated loading dock impacts, forklift strikes, or corrosion. The exact length and configuration of this part could not be determined from available sources; it may be a short repair section, a splice bracket, or an end cap, given its low price point.
