An air return bulkhead is disclosed which may be adapted to fit on differently-sized trailer walls around differently-sized trailer refrigeration units. The bulkhead includes an upper support panel with ridges or other discontinuities thereon. The discontinuities bound areas sized to accommodate standard refrigeration units, and a cutting tool may be easily guided along these discontinuities to form a space wherein the refrigerator may be fit when the bulkhead is mounted to the trailer wall. Also disclosed is a bulkhead which includes flutes and columns thereon wherein the ends of the flutes and columns may be removed by use of a cutting tool to allow the bulkhead installer to tailor the airflow into the refrigerator inlet as desired.

The air return bulkhead of claim 10 wherein at least one of the depressions is spaced from the upper, lower, and side edges of the floating panel. 12. The air return bulkhead of claim 10 further comprising two or more support columns resting below the lower edge of the floating panel,wherein each support column includes opposing column walls descending rearwardly with respect to the rear face of the floating panel, and a column floor situated between the column walls and extending downwardly with respect to the lower edge of the floating panel. 13. The air return bulkhead of claim 12 wherein at least one of the depressions is recessed into the front face of the floating panel directly above one of the support columns. 14. The air return bulkhead of claim 12 wherein at least one of the depressions defines a support flute which includes elongated opposing flute walls extending between opposing flute ends. 15. The air return bulkhead of claim 14 wherein at least one of the flute ends is recessed into the front face of the floating panel directly above one of the support columns. 16. An air return bulkhead comprising:a. a floating panel including opposing front and rear faces, an upper edge, an opposing lower edge, and opposing side edges,b. an upper support panel descending rearwardly from the rear face of the floating panel at its upper edge,c. two side support panels, each side support panel descending rearwardly from the rear face of the floating panel at one of its side edges,d. one or more depressions recessed into the front face of the floating panel between the upper and lower edges of the floating panel,e. two or more support columns, wherein each of the support columns includes opposing column walls extending downwardly with rest to the lower edge of the floating panel and descending rearwardly with respect to the rear face of the floating panel. 17. The air return bulkhead of claim 16 wherein the upper support panel is integrally formed with the floating panel and extends continuously across the width of the floating panel. 18. The air return bulkhead of claim 16 wherein the upper support panel includes spaced ridges defined thereon. 19. The air return bulkhead of claim 16 wherein the upper support panel includes spaced valleys defined therein. 20. The air return bulkhead of claim 16 wherein at least one of the depressions is spaced from the upper, lower, and side edges of the floating panel. 21. The air return bulkhead of claim 16 wherein one or more support columns has an aperture defined therein, wherein each support column having the defined aperture includes a passage defined between its column walls, with the aperture opening onto the passage. 22. The air return bulkhead of claim 16 further comprising one or more lower support panels descending rearwardly from the lower edge of the floating panel between two of the support columns. 23. The air return bulkhead of claim 22 wherein at least one of the lower support panels has an aperture defined therein. 24. The air return bulkhead of claim 16 wherein at least one of the depressions is recessed into the front face of the floating panel directly above one of the support columns. 25.
