I have ~60 gal barrels with lids. The lid is made of two pieces, ring with threads holding down the cover. The opening is fairly large. These previously held pickles.
I have 3 drums for sale at $10.00 each. They held cleaning solution and have been powerwashed inside. Solid one piece design with two small holes in the top, I should have the threaded plugs for the holes in the top.
