This is a composite bottom panel for a heavy-duty roll-up door, commonly found on walk‑in van bodies, trailers, and truck cargo boxes.

We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It forms the lowest section of the door and measures 15 inches tall with a 0.25‑inch wall thickness, making it the impact‑ and corrosion‑prone zone. Replacement is required when the panel is cracked, de‑laminated, or severely dented, restoring weather sealing and door structural integrity.
