NDS Grate Square 9 in. x 9 in. Ductile Iron Black Ductile Iron

Built to stand up to the elements, the heavy-duty 9 in. Square Ductile Iron Catch Basin Drain Grate in ductile iron stands guard on top of the catch basin or low-profile adapter to block pipe-clogging leaves and debris from getting into the pipeline as it drains stormwater. Ideal for moderate flows on driveways, parking lots, and landscaped areas, the 9 in. ductile iron drain grate fits 9x9 catch basin storm drains, extension risers, and low-profile adapters. Ductile iron will rust over time, forming a protective iron-oxide patina that begins red-orange and ages to a deep, rich brown. NDS iron grates are lightly painted black to inhibit rust formation during shipping and storage.
