The NDS 6" Atrium Grate (SKU 80) is a dome-style landscape drain cover engineered to keep leaves, mulch and debris out of your drainage system while allowing efficient surface drainage. Molded from UV-stabilized HDPE, this green atrium grate pairs with 6" Spee-D® catch basins, 6" sewer and drain pipe, and 6" single-wall corrugated pipe for a secure, soil-tight fit.

  • Material: High-density polyethylene (HDPE) treated with UV inhibitors for long outdoor life and color stability.
  • Compatibility: Designed to connect directly to 6" Spee-D® catch basin, 6" drain pipe and fittings, and 6" corrugated pipe.
  • Performance: Open surface area 28.4 sq. in. with a tested flow capacity of approximately 87 GPM for moderate stormwater flows.
  • Dimensions: Overall height 5-3/4"; top diameter 3-7/8"; grate openings approximately 1/4" wide to block large debris.
  • Design benefits: Raised dome traps debris at the base while maintaining drainage through the dome, reducing clogs and maintenance frequency.
  • Maintenance: Removable grate allows easy access to sump and pipe for cleaning and inspection.

Ideal for mulched landscape beds, planter areas, window wells and other locations prone to leaf or mulch buildup, the NDS 6" Atrium Grate offers a durable, easy-to-install solution for directing excess water into pipe networks.
