The 6 Best sealing Septic Tank risers (2023 reviews)

This lid will fit a Polylok riser only, with a 24 inside diameter. It is designed to fit polylok 24" risers, polylok 24" adapter rings, and polylok 24" d-boxes. The plastic expands considerably when heated, and to mesh with the ground component their temperatures have to be somewhat equal or close to each other. The lid is measured by the diameter. This lid will work with a concrete tank if there are existing 24" polylok risers or a polylok adapter ring already in place.

The lid itself does not have a specific space for a padlock, however it does utilize several screws to connect to the riser. This lid will fit directly on to the adapter base (Polylok 3009-AR), if your situation doesn't require a riser.
