Nds 75 4 Inch Green Atrium Grate Flat Top Drain Cover

Product Description

The NDS 75 is a 4-inch flat-top atrium grate designed for surface drainage applications in residential and light commercial settings. Molded from structural foam polyolefin with UV inhibitors, this grate resists degradation from sunlight and outdoor exposure. It provides an open surface area of 14.50 square inches and handles a flow rate of 19.00 GPM, making it suitable for yard drains, planter beds, and landscaped areas. Licensed plumbers and drainage contractors install this type of fitting as part of subsurface and surface stormwater management systems. The green color blends with turf and groundcover in outdoor installations.

This grate is suited for outdoor drain installations where a low-profile, flat-top design is required. It fits into standard 4-inch drain body assemblies and is appropriate for residential yard drainage, garden beds, and similar landscaped or hardscaped areas. The UV-inhibited polyolefin construction makes it a practical choice for exposed installations subject to prolonged sunlight and weather cycles.

Installation Notes

Installation is typically performed by a licensed plumber or drainage contractor. Before servicing or replacing a drain grate, confirm the surrounding drain body is clear of debris and that the pipe connection is sound. Follow applicable plumbing codes, including IPC guidelines, for surface drainage fittings. Do not force the grate into an undersized or damaged drain body, as this can compromise the seal and structural fit.
