Product DescriptionThe NDS 4 is a 6-inch square drain grate made from black plastic, designed to cover surface drainage inlets in residential and light commercial applications. It fits standard 3-inch and 4-inch drain pipes, making it a common choice for landscape drainage systems, catch basins, and surface drain bodies. The grate allows water to pass through while blocking debris from entering the drain line. Plumbers, irrigation contractors, and landscape drainage installers work with this type of grate as a standard finishing component on surface drain installations.This grate is suited for use in yard drainage, driveway edge drainage, patio drainage, and similar outdoor surface water management applications. It is typically installed at grade level on a drain body or catch basin that connects to 3-inch or 4-inch drain pipe. The black finish blends into asphalt, gravel, or dark hardscape surfaces. It is sized at 6 inches square to provide adequate inlet area for typical residential drainage flow rates.Key Features6-inch square footprint fits standard surface drain bodies and catch basinsCompatible with 3-inch and 4-inch drain pipe connectionsBlack plastic construction resists corrosion and UV degradation in outdoor environmentsLightweight at 0.35 pounds for easy handling and installationDebris-blocking grate pattern helps protect the downstream drain lineCompatibilityFits drain bodies and catch basins accepting 3-inch or 4-inch pipe connections.
