The Norwesco 6 Inch Manhole Extension is a molded polyethylene riser that adds height above a tank's manhole opening. It stands 8 inches tall, weighs about 10 pounds, and carries a 24 x 24 inch footprint.
What it does and how it fits
This extension stacks onto an existing manhole to raise the access point, keeping the lid reachable and clear of whatever sits above the tank shell. Because it is a Norwesco riser component, match it to your tank's existing manway opening rather than mixing brands or sizes. It trims to the height you need for your setup.
Material
The polyethylene construction handles the same outdoor and ground-contact conditions as the tank it sits on, with no painting or coating required.
