Nds 16 3 Inch Round Green Drain Grate Polyolefin

Product Description

The NDS 16 is a 3-inch round drain grate molded from structural foam polyolefin with built-in UV inhibitors. It is designed to cover 3-inch drain pipe openings in outdoor and grade-level drainage applications. The open surface area measures 2.60 square inches, and the grate is flow-rated at 3.41 gallons per minute (GPM). The UV inhibitors protect the polyolefin body from sun degradation, making it suitable for exposed installations. Licensed plumbers and drainage contractors install this grate as the final surface cap on residential and light commercial drainage systems.

This grate fits 3-inch sewer drain pipe fittings, 3-inch corrugated pipe, and 3-inch triple wall pipe. It is rated for pedestrian traffic, bicycle traffic, and wheelchair traffic, making it appropriate for walkways, ramps, patios, and accessible pathways. The round profile and green color suit landscape and turf drainage installations where surface aesthetics and ADA-accessible surface load ratings are a consideration.

Installation Notes

Installation is performed by licensed plumbers or drainage contractors following applicable IPC and local plumbing code requirements. Confirm the drain body opening matches the 3-inch nominal pipe size before seating the grate. No adhesive is typically required for standard snap-fit or friction-fit drain grate installations, but verify the drain body manufacturer guidelines. Ensure the grate sits flush with the finished surface grade to maintain proper drainage flow and traffic load distribution.
