NDS 1212 Diamond Drain Grate – 12″ Catch Basin

The NDS 1212 Diamond Drain Grate is a durable, high-performance solution for protecting your stormwater drainage system. Designed to fit 12-inch catch basins, risers, or low-profile adapters, this grate effectively blocks leaves, debris, and sediment while allowing heavy stormwater flows to pass through—ideal for lawns, landscaped areas, patios, and under downspouts.

Constructed from UV-treated high-density polyethylene (HDPE), this grate resists fading and cracking, ensuring long-lasting performance in outdoor environments. Its diamond-patterned design provides optimal drainage while meeting ADA compliance and supporting NDS Class B loads (up to 175 psi) for medium-duty traffic, including cars and light trucks traveling under 20 mph. Available in multiple colors and styles, this grate delivers both functionality and aesthetic versatility for residential and commercial applications.
