Plating lines, anodizing shops, and parts-washing stations run on rows of open-top tanks, and the uncovered ones are always the problem children: solutions drift, rinse water fouls, and the tank nearest the grinder grows a film. The 65COVER - Ronco's molded PE lid for its 65 gallon open top tank - is how one more tank in the row graduates from problem child to closed storage whenever it is not in active use.
At 5 pounds it is genuinely convenient, which is what determines whether a cover gets used or ignored. The molded fit seats on the 65 gallon tank's rim without fiddling, and the polyethylene is the same chemically resistant family as the tank itself - it will stand over acid rinses and cleaning chemistry as long as the tank stands under them.
Ronco molds both halves of the pair in Tustin, California, as it has since 1974. Buying the lid from the tank's own maker is the unglamorous secret to a fit that stays tight for years of daily on-and-off.
The open-top family and the rest of the line are laid out at the Ronco Plastics hub; the freight estimator handles the delivery math. OneSource Plastics is an authorized Ronco Plastics dealer.
