Nds 980 Square Drain Grate 9x9 Inches Black

Product Description

The NDS 980 is a 9-inch by 9-inch square replacement grate designed for surface drainage applications in residential and light commercial settings. Molded from structural foam polyolefin with UV inhibitors, the grate resists degradation from prolonged sun exposure and outdoor moisture. It provides an open surface area of 39.50 square inches and supports a flow rate of 51.75 gallons per minute (GPM). Rated Class B load, it is engineered to handle medium-duty pneumatic tire traffic including automobiles and light trucks traveling at speeds under 20 MPH. Licensed plumbers, drainage contractors, and experienced installers typically handle this type of surface drainage component.

This grate is designed for use with the NDS 9-inch by 9-inch catch basin series, making it a direct-fit cover for those basin units. It is suited for driveways, parking areas, landscaping, and paved surfaces where controlled surface water collection is required. The Class B load rating makes it appropriate for low-speed vehicular zones such as residential driveways and light commercial lots. Its black finish blends with asphalt and dark paving surfaces commonly found in these environments.

Installation is typically performed by drainage contractors or licensed plumbers working on surface water management systems. Ensure the catch basin frame is clean and free of debris before seating the grate.
