Storm Sentinel catch basin inserts are the ideal products for preventing harmful pollutants from washing into storm drains.
The weighted Drain Dam filter bags install easily and help funnel water into the drain while absorbing a small amount of hydrocarbons. When used in conjunction with a curb inlet insert (4346), it is the perfect stormwater management solution for curb inlets without a drop inlet. No special tools required for installation as the 4 lbs bags are equipped with hook strap (velcro) for securing to the Curb Inlet Filter.
