The FERNCO INC PDSC-43 is a downspout adapter designed to transition from a rectangular downspout outlet to a round pipe connection for below-grade or surface drainage. It bridges the gap between typical residential and light commercial gutter systems and the underground drainage lines that carry stormwater away from the structure. The adapter measures 3 inches by 2 inches by 4 inches, making it a compact, direct-fit solution for standard gutter downspout terminations. Plumbers, drainage contractors, and experienced DIYers install this fitting where downspouts meet drain tile, corrugated pipe, or other storm drainage runs.
This adapter is used in residential and light commercial gutter drainage applications where a rectangular downspout outlet must connect to a round underground or surface drain pipe. It is commonly installed at grade level or just below it at the base of a building exterior wall, directing roof runoff into a dedicated stormwater or foundation drainage system. Each unit is sold individually, with a package quantity of 20 units available for trade volume purchases.
Designed as an OEM-style replacement and new-installation fitting for standard rectangular downspout outlets connecting to round storm drain or foundation drainage pipe systems.
Installation is typically performed by a licensed plumber or drainage contractor following applicable local plumbing and stormwater codes. Ensure the downstream drain line is clear and properly sloped before connecting the adapter. Secure the fitting according to the pipe manufacturer's recommendations, and verify that all joints are watertight before backfilling any below-grade connections.
