The buckets are made from polyethylene resin that is impact resistant, protects against warpage, and helps prevent stress cracks. This bucket features a heavy-duty wire bail with notch for hanging, and stacking ribs so the pails come part easier when stacked. 14.75 inch diameter by 13 inch high, holds 20 quarts (5 gallons).
