The Norwesco 20 Inch Lid & 12 Inch Diameter x 25 Inch High Riser Combination is a black polyethylene access assembly that pairs a 20-inch lid with a 12-inch diameter, 25-inch tall riser. At roughly 12 pounds, this is molded polyethylene hardware, not a storage vessel.
What it is and how it fits
The riser is a 12-inch diameter collar standing 25 inches tall, topped by a matched 20-inch lid. Because the lid and riser are sold together as a combination, the two are sized to seat as one unit rather than mixed with other-size covers. The 20-inch lid provides the working access opening once the riser is set. If your access point sits below grade, the 25-inch riser height can be trimmed down to your burial depth before the lid is fitted.
Material notes
Polyethylene construction resists corrosion and outdoor exposure without painting or coating. Confirm the 12-inch riser diameter matches your existing access opening before install, since the collar is not adjustable in width.
