The NDS 2 is a 4-inch square drain grate made from black plastic, designed to cap surface drains connected to 3-inch pipe. It provides a finished, debris-filtering cover at the drain opening, allowing water to pass through while keeping larger debris out of the drainage line. This grate is a standard component in residential and light commercial surface drainage systems. Plumbers, landscapers, and drainage contractors typically install this part when completing yard drains, patio drains, or area drain assemblies.
This grate is suited for outdoor surface drainage applications where a 3-inch pipe connects to a square catch basin or area drain body. Common install scenarios include lawn and garden drainage, driveway edges, patio perimeters, and other locations where standing water needs a controlled outlet. Its square profile fits flush with standard 4-inch square drain bodies in typical NDS-style drainage systems.
Designed as an OEM-style replacement or standard component for 4-inch square area drain bodies accepting 3-inch pipe connections in residential and light commercial surface drainage systems.
Installation is typically performed by plumbers or drainage contractors as part of a surface drain assembly. Before servicing or replacing an existing grate, clear the area of standing water and debris. The grate should seat flush and securely onto the drain body without the need for adhesives in standard installations. Follow local plumbing and stormwater codes for drain placement and pipe sizing requirements.
