The Norwesco 300 Gallon Pest Control Operator Tank is a polyethylene specialty tank built for mobile and stationary spray rigs, sized for crews running 300-gallon batches without stepping up to a full-trailer load. It measures 37 in. high by 36 in. wide by 69 in. long, giving you a low, stable 36 x 69 in. footprint that sits well on a skid, flatbed, or service-body deck. The long axis is the one to check first: you need 69 in. of clear length on your deck, not just the 36 in. width. The tank carries a 1.5 specific gravity rating, so the shell is engineered to hold contents heavier than water at full volume.
Will this tank work for your application?
Filled with water, this 300-gallon Norwesco holds roughly 2,502 lb. of contents (300 gal x 8.34 lb/gal). Because the shell is rated to 1.5 specific gravity, it is approved to carry up to about 3,753 lb. of contents (2,502 x 1.5) - and that higher number is the one to plan around when you fill with anything denser than water. You can recompute for your own mix the same way: a 1.2-SG batch, for example, runs about 3,002 lb. (2,502 x 1.2). Use the rated weight, not the water weight, when you spec your mounting frame, skid, or vehicle payload. The low-profile 37 in. height keeps the center of gravity down for transport and makes top access easy from the ground. If you are deciding between this and another size, run your batch volume through the Tank Sizing Calculator and the Tank Sizing Guide so your fill weight stays inside your rig's rated capacity.

The mistake to avoid
The single most common error on a tank like this is spec'ing the mount around the water weight. This shell is built to a 1.5 specific gravity, meaning it can carry contents up to 50% heavier than water - around 3,753 lb. instead of 2,502 lb. Build your skid, trailer tongue, and tie-downs to the higher number so nothing is overloaded when the tank is full of a heavier mix. One more check: this listing does not publish outlet, bulkhead, or lid sizes, so confirm fitting and lid placement against the technical drawing on this page, or call 866-418-1777, before you plumb the rig - and verify your loaded weight stays under your vehicle's payload rating.
