The NDS 40 is a 6-inch round drain grate molded from structural foam polyolefin with built-in UV inhibitors. It is designed for surface drainage applications where a durable, weather-resistant cover is required over a basin or drain pipe outlet. The open surface area measures 9.11 square inches, supporting a flow rate of 11.92 GPM. Licensed plumbers, irrigation contractors, and drainage installers typically fit this grate as part of a complete catch basin or pipe termination assembly. The black finish blends with standard installations and holds up under prolonged sun exposure without significant color fade or material degradation.
This grate is rated for pedestrian, bicycle, and wheelchair traffic, making it appropriate for walkways, parking areas, ADA-compliant pathways, and light commercial paved surfaces. It fits NDS Speed Basin units, 6-inch sewer drain pipe fittings, and 6-inch corrugated pipe. This makes it a practical choice for residential yard drainage, parking lot inlets, and similar outdoor drainage systems where foot and light wheel traffic is expected.
Fits NDS Speed Basin units, 6-inch sewer drain pipe fittings, and 6-inch corrugated pipe. Recommended for pedestrian, bicycle, and wheelchair traffic applications.
Installation is typically performed by plumbers, drainage contractors, or irrigation professionals. Confirm basin or pipe outlet diameter is 6 inches before fitting the grate. Ensure the basin or pipe assembly is fully seated and stable before placing the grate to avoid misalignment under traffic load. Follow applicable local plumbing and site drainage codes during installation.
