Hero Shot of 9 in. Square Deep-Housing Adapter (NDS 931) which fits 4 in. Corrugated Drain Pipes

The NDS 9 in. Square Deep-Housing Adapter (NDS 931) with a 9 in. green catch basin grate (NDS 990) installed

Capture stormwater and direct it straight to drain pipe with the 9 in. Square Deep-Housing Adapter. The flared-out design covers more surface area than just the pipe diameter alone, and holds more volume than the low-profile adapter. Unlike the catch basin, it has no sump area. The 9 in. Square Deep-Housing Adapter drains heavy flows from lawns, landscaped areas, under downspouts, patios, and walkways, and works with a 9 in. square catch basin drain grate to block debris from entering the pipeline. Connects to 4 in. single-wall and dual-wall corrugated drain pipes; also connects to 4 in. sewer and drain pipe using adapter bushing (sold separately). Made of high-impact polystyrene (HIPS) treated with UV inhibitors.
