The UltraTech 9854 Grate Guard is a sediment-only, high-flow stormwater inlet protection insert designed for 24" x 36" flat storm drain grates. It slides onto the storm drain’s grate and uses heavy-duty hook-and-loop fasteners to secure a high-flow woven filter that captures sediment, silt, and debris while allowing runoff to pass through. Once installed, pollutants are removed from street level with a broom, flat shovel, or similar tools, reducing the need to lift or remove grates during routine maintenance.
- 24" x 36" Inlet Coverage – Sized to fit 24" x 36" (610 x 914 mm) flat storm drain grates, providing full coverage for sediment and debris control at catch basin inlets.
- Sediment-Only High-Flow Design – High-flow woven filtration media captures sediment, silt, and debris while maintaining drainage performance in a sediment-only, no-overflow configuration.
- Hook-and-Loop Grate Attachment – Slides onto the storm drain grate and uses heavy-duty hook-and-loop fasteners to keep the unit closed and secured in place during operation.
- Street-Level Maintenance – Sediment, dirt, and silt can be removed with a broom, flat shovel, or similar tool from street level, minimizing grate handling and simplifying routine maintenance.
- Durable, Reusable Construction – Manufactured from durable, hi-vis polypropylene with high-flow woven fabric and a 2 lb (0.9 kg) unit weight, designed for repeated cleaning and reuse in stormwater BMP programs.
