NDS 9-inch Downspout Defender Grate Low Profile Kit Model 900DSGKIT

Installing catch basins under downspouts is a best practice for managing stormwater and protecting property. Downspout drainage systems move water away from structures where it can do damage. The Downspout Defender makes a drainage system even more effective by capturing more water and deflecting debris to keep the system running clean.
