Auxiliary structural bumpers are adapted to be attached to a main protective bumper assembly for a refrigeration unit of the type adapted to be mounted on the front wall of a trailer. The main protective bumper protects the front of the unit while the auxiliary bumpers are adapted to protect the left and right-hand sides of the refrigeration unit. The refrigeration unit includes an outer cover, and a structural framework, which includes a pair of vertically extending structural elements located at opposite rear corners of the refrigeration unit adjacent to the front wall of the trailer. The main bumper assembly includes two vertically extending structural members, each of which is adapted to be structurally coupled to one of the vertically extending structural elements of the refrigeration unit. A pair of horizontally extending structural members are attached to the upper ends of the vertically extending members at one end thereof and the other ends extend forwardly towards the front of the refrigeration unit. The ends of the horizontally extending structural members, which extend forwardly, terminate at a location forward of the outer cover and spaced from one another. An elongated structural bumper extends substantially horizontally at a location forwardly of the outer cover where it is attached to the other ends of the horizontally extending structural members. Auxiliary structural bumpers are adapted to be positioned to one side of the main structural bumper and outboard of one side of the outer cover of the refrigeration unit. The auxiliary bumpers extend substantially horizontally and are structurally attached at one end thereof to one end of one of the horizontally extending structural members and at the other end thereof to the main elongated structural bumper.
