The STORM DRAIN DEFENDER traps pollutants, reducing and controlling the entrance of contaminants into our water systems.
 
The STORM DRAIN DEFENDER  is a simple sheet of geotextile fabric supported by a wire frame. The standard round models adjust to fit round drains size 27" - 29" in diameter. The entire unit is under the grate, no excess fabric extends above the grate, creating a safer environment for pedestrians. No trimming required.
