20'' & 24" Riser & Covers
These risers combine all the best features of concrete and plastic to offer a superior product. We make risers that hold their shape, are stackable, screw together, and are watertight and airtight. Each riser and cover has a factory installed gasket to ensure a watertight seal. No other riser manufacturer can make that claim!
