a rack for the transport of thin wall parts such as automotive body panels stampings has a steel frame with two parallel channels positioned on either side of a planar floor member . each channel has a series of parallel slots which receive tabs extending downwardly from parallel plastic leaves . the leaves are restricted from removal from the rack by rods which extend through the frame beneath the channels and through rod openings in the tabs . the plastic leaves are of two types having side structures which do not nest . because the leaves are not hinged to the floor member , they will stay in either position due to gravity . the non - nesting leaf side structures permit a plurality of leaves to be flipped from one position to the other simultaneously .
