The Storm Drain Grate Guard is a simple, effective solution for capturing sediment, silt, debris, and oil before they enter storm drains and local waterways. Designed for use with flat grate catch basins, this grate guard installs quickly by sliding directly over the drain grate and securing in place with heavy-duty hook-and-loop fasteners. It allows stormwater runoff to flow freely while filtering out pollutants at the source.

Available in standard and custom sizes, the grate guard helps facilities manage stormwater runoff and support compliance with NPDES, 40 CFR 122.26, and TMDL requirements. Ideal for industrial sites, parking lots, construction areas, and municipal applications, this reusable solution reduces environmental impact while maintaining proper drainage.
