Type of plastic is immaterial. Thickness of the plastic should not exceed 1/16th of an inch. Item 104 is a 22 gauge steel wire cloth, items 108 and 109 are wooden spacers that sit underneath the wire cloth. Items 104, 108 and 109 fill the empty space between the roof of the tool box and the top of the PVC storage tubes. The main requirement is those wooden pieces and wire cloth are adequately secured so that there is no space between the wire cloth and the top of the PVC tubes when the lid is closed.
