Storm Sentinel catch basin inserts are the ideal products for preventing harmful pollutants from washing into storm drains. This frameless model is simple in design but powerful in protection. The weight of the grate holds the unit in place, allowing extra fabric to be cut away for a custom fit. The geotextile fabric prevents contaminated sediment from washing into the drain, protecting you from fines and fees.

• Fits drains up to 60"x60"
• Multiple sizes, models, and custom sizes available
• No special tools required for installation
