The UltraTech 1465 Grate Topper is a high-flow stormwater inlet protection unit designed to fit over rectangular catch basin grates and reduce sediment, silt, and debris entry into drainage systems. Constructed from reinforced geotextile filtration media, it allows stormwater to pass through while capturing particulate runoff in construction and roadway environments. The 28" x 36" configuration is intended for larger rectangular grate applications requiring broad surface coverage and reliable flow-through performance.
- 28" x 36" High-Flow Coverage – Designed to cover larger rectangular catch basin grates, providing full surface protection for sediment and debris control
- Reinforced Geotextile Filtration Media – Heavy-duty fabric allows stormwater flow-through while capturing sediment, silt, and construction runoff particles
- Secure Retention Design – Installed over existing grate structures and held in place by weight and/or fastening system depending on site configuration
- Reusable Construction Grade Build – Designed for repeated use with cleaning and redeployment across multiple job sites, reducing replacement frequency
- NPDES Stormwater Compliance Support – Assists in meeting standard construction site erosion and sediment control best management practices (BMPs)
