Review on Justrite 08530 Polyethylene Vertical Diameter by Mark Walsh

This is such a simple and obvious product. I can't believe I've never seen this before and that it doesn't happen more often. The only problem with this item is that it will rise if you fill the drum too quickly. The escaping vapor pushes it up briefly, but then goes back down after the vapor levels off. It's slightly annoying; but after a while you will be able to tell the difference between a full drum and leaking steam.
