NDS 9P10 PVC Offset Downspout Adapter — 4" x 6" x 6"

Reliable PVC adapter for routing roof runoff into sewer-and-drain systems. The NDS 9P10 is an offset downspout adapter that aligns a 4" x 6" rectangular downspout to a 6" sewer-and-drain (S&D) hub, allowing the downspout to sit close to a building wall while connecting to standard round drainage pipe.

• Material: Durable polyvinyl chloride (PVC) formulated for outdoor drainage use and UV resistance.
• Connection sizes: Accepts a 4" x 6" downspout inlet and connects to a 6" S&D hub for round sewer-and-drain pipe.
• Compatibility: Designed for SDR-35, SDR-26, Triple Wall and ASTM D-2729 pipe; not compatible with DWV Schedule 40 (ASTM D2665).
• Performance: Intended for non-pressurized drainage systems; maximum working pressure is 5 PSI. Meets applicable ASTM standards for sewer-and-drain fittings.
• Installation: Solvent-weld connection provides a secure, permanent joint for below-grade or wall-exit installations.

Made to NDS standards for reliable stormwater routing, the 9P10 offset adapter provides a compact, standards-compliant transition from rectangular downspouts to round S&D piping. Use this adapter when you need a low-profile solution that keeps the downspout flush to the wall while maintaining clear flow into the drainage system.
