Apparatus for protecting a door and rear sill of a trailer comprises a U-shaped body formed of resilient, rubbery material having a web from which two arms extend, the arms being spaced apart a distance sufficient to straddle a sidewall of the trailer. The arms of the body also may embrace not only a sidewall of the trailer but also an adjacent door which occupies a position alongside and parallel such trailer sidewall. The protective body also has a depending lip which projects downwardly from the web a distance to overlap at least a part of the trailer floor sill.
