The Chem-Tainer 50 Gallon PE Rectangular Open Top Tank is a compact open top tank built for batching, washdown, parts soaking, and general water handling where you need clear top access and a small footprint. Made from rugged polyethylene, this 50 gallon rectangular open top tank holds 50 gallons and earns its place when an enclosed tank just gets in the way of the work. It ships LTL from West Babylon, NY, with freight quoted live to your ZIP.
Will this 50 gallon tank work for your job?
You load, mix, and dip from the top of this open tank with nothing blocking access, which is why a rectangular open top tank handles rinse stations, holding, and small-volume transfer well. When you fill it with water, plan around a full water weight of about 417 lb, so the stand, bench, or pad underneath has to carry that load with margin. Polyethylene shrugs off rust and most outdoor exposure. If you are not sure 50 gallons matches your throughput, run the numbers with our Tank Sizing Calculator or read the Tank Sizing Guide before you commit.
Specs and setup
Capacity is 50 gallons in a rectangular open-top format. See the technical drawing on this page for the dimensional footprint and wall detail so you can confirm the tank clears your work area and fits the support you have planned. Because it is open at the top, set it on a flat, fully supported surface — a level concrete pad or a properly sized stand keeps the loaded tank stable. For above-ground pad work, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the framework for getting the base right. Note that this tank ships bare: if you need a drain or side outlet, plan to add a bulkhead fitting and gasket sized to your plumbing.
The mistake to avoid
The common miss on an open top tank is treating that full water weight as an afterthought. At roughly 417 lb full, a 50 gallon tank parked on an undersized table or an unlevel surface can rack, tip, or overload its support. Size the stand or pad for the loaded weight, not the empty tank, and keep it level. If you are aggregating water from more than one source — rainwater, condensate, or grey water — our write-up on industrial water reuse tank topology covers how to band and sequence storage so a small open tank fits cleanly into the larger system.
