NDS 1215 12" Galvanized Steel Square Catch Basin Drain Grate is ideal for draining heavy flows from driveways, parking lots, and landscaped areas. It is compatible with catch basins, risers, and low-profile adapters. The drain grate, also known as a drain cover, protects the drainage system by blocking harmful debris from entering and potentially clogging drain pipes. The 12x12 metal catch basin drain grate resists rust and corrosion, and is built to stand up to the elements. Hassle-free limited lifetime warranty guarantees the NDS product is free from defects, or we’ll replace it.
