Protect landscape and hardscape areas from surface water with the NDS 12-inch square catch basin grate. Made to fit the NDS 12" x 12" catch basin series, this green structural foam polyolefin grate combines generous open area and UV-resistant construction for long-term outdoor performance.

  • Size & fit: Designed for 12 x 12 in catch basin openings; nominal face dimensions fit standard 12" catch basin risers and low-profile adapters.
  • Durable material: Structural foam polyolefin (HDPE/foam polyolefin family) treated with UV inhibitors for chemical resistance, rustproof performance, and fade resistance.
  • Performance: Large open surface area (approx. 50.76 sq‑in) for efficient drainage and an estimated flow capacity near 155 gpm under typical conditions.
  • Load rating: Rated NDS Class B for medium-duty pneumatic tire traffic (recommended for light auto traffic and similar applications when properly installed).
  • Low profile & lightweight: Approximately 1‑1/8 in height and roughly 2–3 lb weight make handling and installation easy while allowing use in yards, patios, driveways, and landscape areas.

Ideal for residential and light commercial drainage, the NDS 1212 grate filters larger debris while letting runoff pass into the catch basin below. It installs quickly onto compatible 12" x 12" catch basin tops, risers, and low-profile adapters and can be secured with the appropriate fasteners. For heavy-duty vehicular applications or specialized installations, consult local codes and the NDS product literature to confirm compatibility and load requirements.
