This is the official product video for the Norwesco 20 Inch Lid & 12 InchD x 25 InchH Riser Combination. Full specifications, dimensions, and live pricing are on the product page.
Black polyethylene...heavy with purpose. A matched pair: a 20-inch lid and a 12-inch diameter, 25-inch tall riser...molded polyethylene hardware, not a storage vessel. At roughly 12 pounds, it is a single, seated unit—sized to lock together, not mixed with other covers. The 20-inch lid becomes the working access opening once the riser is set. If your access sits below grade, the 25-inch riser height can be trimmed down to your burial depth before the lid is fitted. Confirm the 12-inch riser diameter matches your existing access opening...because the collar is not adjustable in width. Norwesco 20 Inch Lid & 12 InchD x 25 InchH Riser Combination. Precision Access Fit. OneSource Plastics.
