StormDrain FSD-3009 6in Riser for 20in Catch Basin

The StormDrain FSD-3009 6-inch Riser is engineered to bring your 20-inch catch basin to grade seamlessly. Constructed from heavy-duty polyethylene, this riser combines the durability of concrete with the flexibility and resilience of high-quality plastic. Unlike polypropylene alternatives, it resists shattering and maintains structural integrity in demanding conditions.

Key features include internal structural ribs to prevent frost adhesion in cold climates, ensuring reliable performance year-round. The riser is stackable and designed for straightforward screw-together assembly, delivering a watertight and airtight seal. Note that the lid, grate, and basin must be purchased separately. Proudly made in the USA for lasting reliability in stormwater management.
