NDS 9" x 9" Deep-Housing Spigot Adapter for 4" Corrugated Pipe

The NDS 9" x 9" Deep-Housing Spigot Adapter provides a durable, low-profile housing that captures surface water and directs it into 4" drainage pipe. Made for landscape, yard, and hardscape drainage, it pairs with 9" square grates to block debris while allowing high flow rates. Its flared design holds more surface area than a simple pipe opening and, unlike a full catch basin, has no sump area, making it ideal where sediment accumulation is minimal.

• Compatible pipes: Connects to 4" single-wall and dual-wall corrugated drain pipe; use NDS #933 adapter bushing to connect to 4" sewer & drain pipe.
• Materials: High-impact polystyrene (HIPS) treated with UV inhibitors for outdoor durability.
• Dimensions: 8" overall height; top opening measures 10-7/8" square; accepts 9" x 9" square grates (grates sold separately).
• Applications: Ideal for lawns, landscaped areas, under downspouts, patios, and walkways where surface runoff must be captured and routed to pipes.
• Installation notes: Requires a universal outlet for each opening (for example, NDS #1206, #1243, #1245, or #1266) and a compatible 9" grate.

Color: black. Grate and outlet components sold separately. Refer to NDS drainage literature for detailed installation guidance and part compatibility.
