Polylok pdb-ds03 Downspout Adapter 2x3 to 4 in

Product DescriptionThe POLYLOK pdb-ds03 is a downspout adapter designed to connect a 2-inch by 3-inch offset downspout pipe to 4-inch drainage pipe. It is compatible with 4-inch corrugated, Schedule 40, and SDR 35 pipe types, making it a flexible fitting for residential and light commercial drainage work. Constructed from polypropylene, the adapter resists moisture, soil contact, and the expansion and contraction cycles common in exterior drainage installations. It ships in white finish. Landscapers, drainage contractors, and plumbers install this fitting when routing roof runoff from a gutter downspout into an underground or surface drainage line.This adapter is suited for residential exterior drainage systems where a rectangular offset downspout must transition into a round underground pipe. Typical applications include yard drainage tie-ins, french drain inlets, and foundation drainage routing. The adapter handles the geometry change from the rectangular 2-inch by 3-inch downspout profile to the round 4-inch pipe without the need for additional reducing fittings. It is commonly installed at grade level or just below where the downspout terminates.Key Features Connects 2-inch by 3-inch offset downspout to 4-inch round pipe Compatible with 4-inch corrugated, SCH 40, and SDR 35 pipe Polypropylene construction for moisture and UV resistance in exterior installations White finish suitable for above-grade visible installations Single-piece adapter eliminates the need for additional reducing couplings CompatibilityDesigned to connect 2-inch by 3-inch rectangular offset downspout pipe to 4-inch corrugated pipe, 4-inch Schedule 40 pipe, or 4-inch SDR 35 pipe.Installation NotesInstallation is typically performed by plumbers, drainage contractors, or experienced landscapers.
