Catch Basin Kit with Atrium Grate 12″ x 12″


12″ x 12″ Atrium grate catch basin w/choice of outlets and outlet size.



The NDS 12″ x 12″ Atrium Catch Basin Kit is a complete residential catch basin system for drainage in flowerbeds and around your hardscape. Slots in the atrium grate catch leaves and chunks of mulch while the dome shape assures drainage will continue even as the bottom of the grate begins to plug.  Choose 2 outlets if the catch basin will be inserted into a run of pipe.


The NDS catch basins, grates and adapters we offer are commercial grade – not the budget ones you find at your local big box hardware store.

The atrium grate is available in black or green.
Suitable for:

  • Downspout Drainage
  • Hardscape Drainage
  • Flowerbed Drainage

The 12” catch basin kit stops leaves and silt from clogging your pipes by holding the debris in a reservoir. Let our catch basin drain your leaf litter worries! Don’t forget to add on a Catch Basin Filter.

The catch basin assembly includes:

  • 1 catch basin w/2 openings (12″ x 12”)
  • Choice of one or two outlets
  • Choice of outlet size(s) – 3″/4″ pipe adapter or 6″ pipe adaptor
  • 1 polyolefin domed atrium grate of preferred color
  • 2 stainless steel fasteners for grate
  • Installation instructions

Each catch basin kit is designed for maximum durability and drainage. UV inhibitors in the grates and component parts prevent fading and cracking from the sun, ensuring a lasting product. All of our polyolefin grates are chemically resistant, rustproof, and maintenance-free.
