About This Product
This Polylok 20-inch diameter riser is a solid choice for bringing your septic tank access up to ground level.
Made from high-density polyethylene, it won't shatter like cheaper polypropylene risers, and it's built to handle the elements.
It's watertight and airtight, so no odors escape and no groundwater seeps in.
This works with other Polylok 20-inch products—riser extensions, covers, safety screens, and adapter rings—so you can stack them to get the height you need.
Riser gasket is sold separately (part number 3009-HR).
Proudly made in the USA.
Durable, reliable, and easy to work with for any septic system maintenance.
