Wirthco EZ Smart Drum Funnel With Cover & Extended Spout

With the funnel extension, trapped air stops the liquid from filling to the top of the barrel. It leaves just enough room to add 2 gallons more to the barrel, which is the capacity of the E-Z SMART DRUM FUNNEL. Stop overfilling your barrels with the E-Z Smart Drum Funnel. An ingenious design improvement that will not allow the barrel to overfill. Includes Cover.
