Designed for catch basin filtration – captures sediment, debris, and pollutants before they enter stormwater systems

High-capacity vertical design – cone-shaped “witches hat” provides increased sediment storage for heavy flow conditions

Installs below the grate – hangs inside the catch basin to filter runoff at the point of entry

Durable geotextile construction – built to withstand high-flow storm events and demanding job site conditions

Allows water flow while filtering contaminants – maintains drainage while reducing sediment and pollutant discharge

Helps prevent clogged drainage systems – reduces sediment buildup in stormwater pipes and infrastructure

Supports environmental compliance – helps meet stormwater management regulations

Ideal for construction and roadside applications – suitable for roadwork, urban development, parking lots, and industrial sites

Easy to install and maintain – Lift grate and place fabric of product entirely over the opening. Gently place the grate back over the drain, ensuring that the grate is "pinching" the fabric in order to keep it in place.
