Abstract: A foldable handrail assembly for use with an entrance in a wall of an enclosure such as a trailer or the like. The foldable handrail assembly includes a handrail which may be extended from and locked at an angle to the trailer wall for use with the entrance or retracted and folded flat against the wall for storage. The foldable handrail assembly includes the handrail, a first mounting bracket, a length adjustable brace, a stabilizer rod and a stabilizer rod mounting bracket. The stabilizer rod as well as the stabilizer rod mounting bracket may be mounted in either an upper or lower position with respect to the handrail to prevent interference with existing components of the wall.
