24" X 12" Riser (Wall Flats)

The 24" x 12" risers from Polylok can be conveniently stacked and attached to other Polylok items, including adapter rings, distribution boxes, and catch basins, using their screw holes. Constructed with high density Polyethylene, these risers offer excellent water and air sealing, as well as the strongest UV-Ray protection available. They are suitable for vacuum or water testing and provide ground-level access to septic systems. Furthermore, they are built to withstand frost with the inclusion of a tear-off riser ring.
