This is the Norwesco Applicator Tank - 200 Gallon (38 Inch Diameter). Whether you're looking for a new or replacement tank, you'll find it in the Norwesco line. All Norwesco applicator tanks feature a lid which threads directly into the fill-opening of the tank to prevent the sloshing or leaking of tank contents during transport or application. Applicator tanks are most often used when complete drainage is required. They may be used for transporting water, chemicals, fertilizers and other liquids. Our Norwesco Applicator Tanks are constructed with a UV stabilized resin and a specific gravity rating of 1.5 (12.5 lbs per gallon).
