The UltraTech 1466 Grate Topper is a high-flow stormwater inlet protection device designed to cover flat grate catch basins and reduce sediment, silt, and debris entry into drainage systems. It is built from durable, high-flow geotextile material with a reinforced support structure to maintain stability under traffic and stormwater load conditions. The 30" x 30" configuration provides a standardized fit for common square grate applications in construction and municipal drainage control environments.
- 30" x 30" Standard Grate Coverage – Designed to fit common square catch basin grates, providing full surface coverage for sediment and debris control in high-flow environments
- High-Flow Geotextile Filtration Media – Engineered filter fabric allows stormwater to pass through while capturing sediment, silt, and construction site runoff particles
- Reinforced Retention System – Secures over existing grate structures using a weighted or frame-supported design to prevent displacement during storm events or traffic exposure
- Reusable Construction Design – Built for repeated use with cleaning and redeployment capability across multiple job sites, reducing replacement frequency
- NPDES Compliance Support – Helps support stormwater pollution prevention requirements under standard construction site best management practices (BMPs)
