The Chem-Tainer 112 Gallon PE Rectangular Open Top Tank is a 112-gallon open-top polyethylene vessel built for water storage, batch mixing, and process staging where you need fast top access. The rectangular footprint uses floor space efficiently against a wall or in a row, and the open top lets you fill, dip, clean, and inspect without working through a small port. If you have searched for an open top tank, an open tank, or a rectangular open top tank, this is that tank in a shape that drops neatly onto a pad or platform.
Will it work for your job?
Filled with water, this tank carries roughly 934 pounds, so the surface under it has to be flat, level, and rated for that load before you fill. Plan for the full-water weight, not the empty shell, when you spec a stand, a mezzanine, or a concrete pad. The exact length, width, height, and the wall and base layout are on the technical drawing on this page; check those footprint dimensions against your available space and any overhead clearance before you order. To size the tank to your actual draw or holding volume, run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide so you are not guessing on capacity.
What it is, and what it is not
This is a bare open-top vessel. It ships with no pre-installed outlets, bulkhead fittings, drains, or gaskets, so any plumbed connection is a separate part you drill and install yourself in the flat sidewall or floor. As an open tank, it is not a pressure or sealed-transport vessel; use it for static storage and batching, not closed systems. It is rated for water and water-like fluids near 1.0 specific gravity. For heavier chemicals or higher specific gravity, you need a thicker-wall closed tank instead, not this open vessel, and a quick call to 866-418-1777 will get you pointed at the right one.
Setup and support notes
The open rim is the natural place to add a cover, splash control, or a lid you supply, and the flat sidewalls make bracketing and labeling straightforward. If you are setting it outdoors or on a new slab, the concrete pad sizing guide for above-ground polyethylene tanks walks through the ACI framework for supporting a tank of this weight, and the industrial water reuse topology guide covers where an open rectangular tank fits in grey-water, rainwater, and condensate staging trains.
Freight
This tank ships LTL freight from West Babylon, New York, with the carrier quoted live to your ZIP code, so the rate reflects your distance and delivery details rather than a flat number. Get your exact freight number with the Freight Cost Estimator, or call 866-418-1777 and we will quote it and answer setup questions before you buy. The most common mistake on an open-top tank is treating it like a sealed tank, planning the pad for the empty weight, or skipping the level check; size the support for the full 934-pound water load and confirm your footprint against the technical drawing first.
