UltraTech 1462 Grate Topper, 24" x 24", High Flow, Green

The UltraTech 1462 Grate Topper is a specialized stormwater management component engineered to capture sediment, silt, and debris directly at street level. Fabricated from a durable high-flow woven geotextile material, this low-profile guard slides easily over standard catch basin grates and is secured using heavy-duty hook-and-loop fasteners. Keeping all trapped pollutants above the drain structure allows field personnel to clear accumulated contaminants quickly without lifting heavy, hazardous metal grates. This robust system is specifically optimized for municipal maintenance crews, construction site compliance coordinators, and industrial procurement managers seeking dependable run-off control.

• High-Flow Woven Geotextile - Constructed with specialized fabric that delivers a high permittivity and flow rate of 250 gallons per minute per square foot to prevent localized street flooding.
• Street-Level Maintenance - Eliminates the need to pull heavy iron grates by keeping all filtered silt, sand, and dirt accessible for fast cleanout with a standard broom or flat shovel.
• Heavy-Duty Fastening System - Integrates industrial-grade hook-and-loop closures to wrap around the frame structure, ensuring the topper remains anchored during severe storm surges.
• Regulatory Compliance Support - Assists facilities in fulfilling strict National Pollutant Discharge Elimination System requirements, helping meet EPA 40 CFR 122.26 and TMDL stormwater regulations.
• Built-In Overflow Ports - Features integrated overflow ports that allow excessive bypass volume to pass safely during extreme downpours while preventing catastrophic street pooling.
