Polylok 123008HD 12 Inch Heavy Cover Septic Riser Lid

Product Description

The POLYLOK 123008HD is a 12-inch heavy-duty septic riser cover designed to provide a secure, durable lid for septic system access risers. Built to handle demanding load conditions, this cover is engineered for installations where a standard-weight lid is not sufficient. It is sold as a single unit and carries the model designation 3008-HD. Septic system installers and service technicians typically specify heavy covers for applications subject to vehicular or equipment traffic, or where local code requires a higher load-rated closure on an access riser.

This cover is intended for use with 12-inch diameter septic system risers in residential and light commercial wastewater applications. It fits installations where a 12-inch riser tube brings the tank access point to or near grade. The heavy-duty construction makes it appropriate for sites where the cover may be subject to surface loads beyond typical foot traffic. Plumbers, septic system installers, and licensed wastewater contractors are the primary installers of this component.

Installation Notes

Installation should be performed by a licensed septic system installer or plumber in accordance with local and state wastewater regulations. Always pump down or confirm the tank is safe to access before removing or replacing any riser cover. Ensure the riser pipe seating surface is clean and undamaged before seating the new cover. Verify local code requirements for load rating and cover securing methods prior to installation.
