The UltraTech 9859 Grate Guard, Sediment Model is a high-flow curb-style stormwater inlet protection device designed for 18" x 36" flat grate catch basins. It slides onto the storm drain grate and uses heavy-duty hook-and-loop fasteners to secure a high-flow woven sediment filter, allowing maintenance and cleanout at street level without removing the grate. Configured as a sediment-only, curb-style unit with no overflow ports, it provides controlled sediment capture while maintaining stormwater flow at curb inlets.
- 18" x 36" Grate Coverage – Sized to fit 18" x 36" (457 x 914 mm) storm drain grates, providing curb-style coverage for sediment and debris control at flat grate catch basins.
- Curb-Style with 44" Deflector – Curbside configuration with a curb deflector (44" per product title) to intercept runoff along the curb line and direct it into the filter area for improved capture efficiency.
- High-Flow Sediment-Only Design – High-flow woven filtration media allows stormwater to pass while capturing sediment, silt, and debris, with no oil-absorbent media and no overflow ports.
- Hook-and-Loop Grate Attachment – Slides over the storm drain grate and secures with heavy-duty hook-and-loop fasteners, enabling cleaning at street level using a broom or shovel without grate removal.
- Durable, Reusable Construction – Manufactured from durable, high-visibility polypropylene, high-flow woven fabric with a large containment area, designed for repeated cleaning and reuse in stormwater BMP programs.
