Advanced Drainage Systems 364 Aa Downspout Adapter Hdpe

Product Description

The ADVANCED DRAINAGE SYSTEMS 364 AA is a single-wall corrugated HDPE downspout adapter designed to connect residential and commercial downspouts to corrugated drainage pipe. It bridges the transition point between a building's gutter outlet and the underground or surface drainage system, directing roof runoff away from foundations and structures. The adapter measures 2 x 3 x 3 inches and is constructed from high-density polyethylene (HDPE), a material known for resistance to corrosion, soil chemicals, and UV degradation. Plumbers, drainage contractors, and experienced DIYers install this fitting as part of stormwater management systems.

This adapter is suited for residential and light commercial downspout-to-drain connections where single-wall corrugated pipe is used. It is commonly installed at grade level or buried in shallow trench applications to route water from gutter downspouts into yard drains, French drains, or perimeter drainage systems. The compact 2 x 3 x 3 inch form factor makes it appropriate for standard residential gutter configurations.
