This is the official product video for the Norwesco 20 Inch Underground Tank Lid. Full specifications, dimensions, and live pricing are on the product page.
From the earth... a close, quiet guardian. The Norwesco 20 Inch Underground Tank Lid is the low-profile access cover for 20-inch riser openings on underground and septic-style systems. It measures 20 inches across, stands 4 inches tall, and weighs about 4 pounds. Molded from black polypropylene to withstand UV and weather exposure at grade level, it is an LP lid with integral gasket... the gasket seats against the flat sealing face to form the seal. This is a replacement or spare access lid, not a tank; lid families are not cross-interchangeable between diameters. Precision fit. Silence secured.
