Small open-top tanks lose a surprising share of their contents to the air. A 10 gallon batch of solution has a lot of surface area relative to its volume, so an uncovered tank sitting between uses is quietly evaporating money - and drifting in concentration while it does. The 10COVER, the molded PE lid for Ronco's 10 gallon open top tank, is the two-pound answer.
The fit is the point. This lid is molded to the rim of the matching Ronco tank, not a generic disc balanced on top, so it seats properly and stays put. On for storage, off for the batch; at 2 pounds there is zero friction to actually using it, which is what separates covers that protect solutions from covers that live on a shelf.
It comes from the same Tustin, California plant that has molded Ronco tanks since 1974, in the same polyethylene family - chemically compatible with whatever the tank body itself is rated to hold, so lid and tank age together instead of the cover failing first.
Order it alongside the matching open-top tank, or see everything the plant molds at the Ronco Plastics hub. Shipping is priced in seconds at the freight estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
