Advanced Drainage Systems 0364AA Downspout Adapter 2x3x3 in

Product Description

The ADVANCED DRAINAGE SYSTEMS 0364AA is a poly downspout adapter designed to transition between a 2 x 3 inch rectangular downspout opening and a 3-inch round drain tube outlet. Made from durable polyethylene, this adapter connects residential and light commercial gutter downspouts to underground drainage systems or surface drain piping. Plumbers, drain installers, and skilled general contractors use this fitting to route roof runoff away from foundations. The unit weighs 2.38 pounds and is sold individually, with a package quantity of 24 units per case for job-site stocking.

This adapter is suited for residential and light commercial drainage installations where a rectangular gutter downspout must connect to a round poly drain tube. It is commonly installed at grade level or just below, bridging the gutter downspout outlet to a buried French drain, a pop-up emitter line, or a surface drainage channel. Its polyethylene construction resists moisture, soil contact, and the UV exposure typical of exterior drainage work.

Key Features

• Transitions a 2 x 3 inch rectangular downspout to a 3-inch round poly drain tube
• Polyethylene construction provides moisture and UV resistance for exterior use
• Lightweight at 2.38 pounds for easy handling during installation
• Sold as an individual unit with a 24-unit case pack for volume stocking

Compatibility

Designed as an OEM-style replacement fitting for standard 2 x 3 inch rectangular residential downspout outlets connecting to 3-inch round poly drain tubing systems.

Installation Notes

Installation is typically performed by plumbers or drainage contractors following local storm drainage codes. Shut off any upstream water sources and ensure the downspout is secured before fitting the adapter. Use appropriate solvent cement or mechanical fasteners as required by the drain tube system being connected. Confirm the outlet pitch meets local grading requirements to ensure positive drainage flow away from the structure.
