The NDS 1830 18 in. Square Low-Profile Catch Basin Adapter is a durable polystyrene adapter designed for yard and area drains. Its low-profile layout collects surface water while reducing the amount of debris that enters the drainage system. The adapter pairs with 18 in. square grates (sold separately) to create a low-visibility, clean installation that keeps finished surfaces level.

  • Universal outlet compatibility: Accepts NDS outlet adapters to connect 3 to 8 in. pipe (examples: #1243, #1245, #1266, #1888).
  • Includes reducer rings: Ships with NDS #1890 reducer rings for a secure bottom outlet connection.
  • Durable polystyrene construction: Weather-resistant black plastic built to withstand soil contact and normal outdoor exposure.
  • Compact dimensions: Top opening measures 17-7/8 in. square and adapter height is 3-5/8 in., fitting standard 18 in. catch basin grates.
  • Grate sold separately: Works with NDS 18 in. grates or compatible square grates; select a grate based on pedestrian or vehicular load requirements.

Installers should pair the 1830 adapter with the appropriate NDS universal outlet adapter and pipe to create a soil-tight connection. The low-profile design minimizes trip hazards and maintains a flush look with surrounding surfaces. Regular debris checks and routine maintenance will help prevent clogs and extend service life.
