The NDS 1206 is a 6-inch universal plug adapter designed to seal or transition outlet ports in NDS catch basin drainage systems. It provides a secure, flush fit within the basin wall opening, blocking unused outlets or preparing a port for future pipe connection. Licensed plumbers and drainage contractors typically specify this fitting during new installation or when modifying an existing storm drainage layout. The adapter is sold in a package quantity of 20 units, making it practical for larger residential or commercial site drainage projects.
This adapter is engineered for use with the NDS 9-inch, 12-inch, 18-inch, and 24-inch catch basin series. It is commonly installed in surface drainage systems where multiple outlet ports are cast into the basin body and only select ports are active. Unused ports are plugged during rough-in to prevent debris infiltration and maintain system integrity across parking lots, driveways, athletic fields, and landscaped areas.
Compatible with NDS 9-inch, 12-inch, 18-inch, and 24-inch catch basin series as stated by the manufacturer.
Installation is typically performed by licensed plumbers or drainage contractors following applicable local plumbing and site drainage codes. Before servicing or modifying an existing catch basin system, ensure all upstream flow is stopped and the work area is clear of standing water. The adapter should be seated fully and evenly into the basin outlet port; consult the NDS catch basin installation guide for seating and sealing requirements specific to each basin size. Do not force-fit an adapter into a mismatched port size.
