Reliable universal locking outlet for NDS catch basins, engineered to connect 3" and 4" drainage pipe types. Durable, low-profile design simplifies installation and provides a secure, soil‑tight connection for surface and subsurface drainage systems.

  • Fits 3" and 4" corrugated pipe, sewer & drain pipe, SCH 40, and triple wall pipe.
  • Material: high-impact styrene (HIPS) with UV stabilizers for outdoor durability.
  • Locks into keyed basin opening using flex tabs—creates a soil‑tight connection without tape or glue.
  • Compatible with NDS catch basin series: 9", 12", 18" and 24" and adapters #930, #1230, #1830, and #2410 (24" also requires #2410).
  • Compact dimensions: approximately 2-1/4" overall height for a low-profile fit.

Installation tip: press the outlet into the keyed basin opening until the flex tabs lock; confirm pipe alignment and test with water flow to ensure a tight seal. No solvent cement is required for the locking connection on compatible pipes.

Ideal for residential and light-commercial drainage projects, the NDS 1243 outlet makes it easy to adapt multiple pipe types to standard NDS basins. Inspect fittings regularly and replace if damaged to maintain reliable drainage performance.
