Designed for reliable drainage connections, the NDS 1245 Offset Universal Locking Outlet provides a secure, adjustable connection for 3" and 4" drainage piping. Its offset spigot and locking tabs allow installers to fine-tune inlet height while maintaining a watertight path from the catch basin to the drain pipe.

  • Compatibility: Fits 3" and 4" corrugated pipe, 3" and 4" sewer & drain pipe, 4" SCH 40 pipe, and 4" triple-wall pipe.
  • Catch Basin Integration: Works with NDS 9", 12", 18" and 24" catch basin series; using with a 24" catch basin requires the #2410 adapter. Common adapters include #930, #1230, #1830 and #2410.
  • Materials & Durability: Molded from high-impact polystyrene (HIPS) treated with UV inhibitors for long outdoor life; lightweight and made in the USA.
  • Adjustable Inlet Height: Offset design permits vertical adjustment to align pipe runs and final grade without additional excavation.
  • Easy Installation: Snap-fit locking outlet attaches to most 3"–4" corrugated pipe; for a tighter seal, apply a bead of waterproof silicone before assembly.
  • Color & Packaging: Black finish; packaged weight approximately 0.5 lb (per NDS specification).

Ideal for residential and light-commercial stormwater and yard drainage systems, the 1245 outlet simplifies connections between catch basins and a variety of pipe types. Its universal fit reduces the number of adapters needed on site and speeds installation for contractors, landscapers, and DIY installers.
