The Norwesco N-64448 is an 18 inch threaded lid with a vent, molded in black polypropylene. It threads onto an 18 inch access opening, and the built-in vent lets air move in and out as the level rises and falls, so the opening is not sealed shut during normal filling and draw-down. At about 18 inches across and 4 inches tall, it seats over the 18 inch opening it is sized for.
What it fits and how it seats
This is an 18 inch threaded lid. Because access openings are sized and threaded to a specific fitting, measure your existing opening and confirm it is an 18 inch thread before ordering, so the lid engages fully and the vent sits clear of the rim. Model-matched lids like this are not interchangeable across different opening sizes.
Material and handling
The lid is polypropylene throughout. At roughly 5 pounds it is light enough to install and remove by hand.
