The Chem-Tainer 50 Gallon PE Rectangular Open Top Tank is a compact, open top polyethylene container built for batching, washdown, parts soaking, and point-of-use water handling where you need full access from the top. At 50 gallons in a rectangular open top footprint, it sets cleanly against a wall or onto a bench, and the open top lets you dip, scoop, mix, or drop a transfer pump straight in without fighting a small fill port.
Will this open top tank work for my job?
This is a 50 gallon rectangular open top tank molded from polyethylene by Chem-Tainer. Filled to capacity with water, it carries roughly 417 lb, so plan your support accordingly: set it on a flat, fully supported, level surface that can hold the loaded weight, not on a stand that only touches the corners or a shelf rated below that figure. The rectangular shape uses floor space efficiently, and the open top gives you unobstructed access for manual filling, stirring, or running a transfer pump over the rim. If you are unsure whether 50 gallons matches your draw-down or storage need, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you buy. For the exact molded dimensions, footprint, wall detail, and any cast-in features, see the technical drawing on this page.
What ships with it, and what to watch for
This is an open top tank, so it is supplied as the rectangular vessel itself. There are no pre-installed fittings called out for this model, so if you need a side or bottom drain, plan a bulkhead fitting with a service-appropriate gasket as a separate add-on, plus an overflow fitting if you want a high-level path, rather than assuming a bottom port is included. The most common mistake on an open top tank is treating it as a closed, pressure-capable vessel: it is not. Keep it vented and open as designed, support the full base under the loaded 417 lb water weight, and remember that an open top invites debris, evaporation, and splash, so cover or locate it accordingly. If your real job is solids handling or a clean drain heel rather than an open rectangle, a cone-bottom tank may serve you better; our Chem-Tainer cone-bottom 30 vs 45 degree drainage comparison walks through that tradeoff.
