The UltraTech 9863 Grate Guard, Sediment Model is a high-flow curb-style stormwater inlet protection device designed to slide directly onto a 28" x 42" grate and control sediment, silt, and debris at street level. Its integrated 50" curb deflector manages flow at curb inlets while the high-flow woven fabric allows runoff to pass through without lifting the grate for cleaning. The unit is configured as a sediment-only model with no overflow ports and is supplied in a green, high-visibility finish for field identification.
- 28" x 42" Grate Coverage – Sized to fit 28" x 42" (711 x 1,068 mm) storm drain grates, providing full curb-style coverage for sediment and debris control at curb inlets.
- Curb Deflector, 50" Length – Integrated 50" (1,270 mm) curb deflector extends along the curb line to direct runoff into the unit and improve capture efficiency.
- High-Flow Sediment-Only Design – High-flow woven filtration media allows stormwater to pass through while capturing sediment, silt, and debris, with no oil-absorbent media and no overflow ports.
- Hook-and-Loop Closure Attachment – Slides over the grate and uses heavy-duty hook-and-loop fasteners to secure the unit in place, allowing cleaning at street level without grate removal.
- Reusable, High-Visibility Construction – Manufactured from durable, high-flow woven material in a green color for visibility, designed for repeated cleaning and reuse in stormwater maintenance programs.
