Abstract: A device for spacing perishable or frozen products from the sides of refrigerated trailers, containers, trucks, railroad cars and the like includes a pair of vertically spaced, elongated cables, brackets for mounting the cables to the sidewalls of the trailer and a plurality of elongated slats or ribs. The slats define upper and lower apertures through which the cables are threaded. The slats are slidably movable from a stored position in abutting relationship to an operative position spaced along the cables and the sidewalls of the trailer. The slats have a generally U-shaped cross section to define additional air channels.
