NDS 1280 12" Square Atrium Grate in green is a lightweight, UV-stabilized HDPE drain grate designed to fit NDS 12" square catch basins. It intercepts debris while directing surface water into the drainage system, making it ideal for planter beds, mulched landscapes, window wells, patios, and other areas prone to leaf and mulch accumulation.

  • Material: UV-stabilized high-density polyethylene (HDPE) for chemical resistance and long-term outdoor use.
  • Dimensions: 11.75" x 11.75" x 6" — fits NDS 12" square catch basins and low-profile adapters.
  • Performance: 50.6 sq. in. open surface area, ~155 GPM flow capacity, 3/8" grate openings for effective debris screening.
  • Benefits: Rustproof, maintenance-free, lightweight, and easy to install; UV inhibitors minimize fading and cracking.
  • Compatibility: Designed to work with NDS 12" catch basin series, risers, and low-profile adapters.

Install the grate into the matching 12" catch basin or low-profile adapter to provide reliable surface drainage for landscapes and light pedestrian areas. Constructed from durable HDPE/polyolefin with UV protection, the NDS 1280 maintains strength and color over time with minimal upkeep. Includes one 12" square Atrium grate; consult NDS technical documentation for installation details and load-class guidance.
