This is a bottom slat for a semi-trailer roll-up door, typically made of aluminum or galvanized steel.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
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 horizontal panel that seals the door against the trailer floor, taking the brunt of fork impacts and weather exposure. When the original slat becomes bent, corroded, or damaged, replacing it with this component restores the door's seal, smooth operation, and overall structural integrity.
