The Enz USA 3/4-inch drainage channel nozzle is suited for cleaning stormwater drains that use channels, for example along roadways, pedestrian zones and parking lots. The spray pattern of the water jets prevents any water from splashing up directly. Afterward, cleanup around work areas is virtually eliminated. This nozzle is ideal for flushing out debris, gravel, leaves and grass. 877-362-8721; www.enzusainc.com.
