34" x 34" 2 Mil Drum Poly Cap Sheets - 55 Gallon with overhang

34" x 34" 2 Mil Cap Sheets with overhang come perforated on a roll for easy dispensing. After you've inserted a plastic drum liner, completely seal off contents with a plastic cap sheet. This keeps contents from coming in direct contact with the metal lid, preventing contamination. For 55 gallon drums that need a little extra coverage over the opening, the 34" x 34" cap sheet is an excellent fit.
