The Amerimax ADP53102 FLEX-Drain Downspout Adapter is a high-performance, flexible solution designed to connect rectangular downspouts to round drainage pipes with ease and reliability. Whether you're managing stormwater runoff or building a custom drainage system, this adapter offers the durability, versatility, and ease-of-use that professionals and DIYers alike demand.

Key Features:

• Universal Compatibility:
  This adapter connects a 3" x 4" rectangular downspout to 4" corrugated pipe or 4" PVC pipe, making it ideal for a wide range of residential and commercial drainage applications 

• Flexible, Space-Saving Design:
  The flexible copolymer construction allows the adapter to bend and conform to tight or awkward spaces, making installation easier in areas where rigid fittings would be difficult to use 

• Durable, No-Break Copolymer Construction:
  Built from high-strength, UV-resistant copolymer, this adapter resists cracking, corrosion, and environmental wear. It exceeds all applicable ASTM crush standards, ensuring long-term performance even under heavy loads

• Soil-Tight, Snap-Lock Fittings:
  Integrated soil-tight fittings lock securely into place without the need for tape or sealants, maintaining a strong, leak-resistant connection during backfilling and over time 

• Quick and Tool-Free Installation:
  Simply push-fit the adapter into place—no tools, glue, or clamps required. It’s a fast and efficient way to transition from downspout to underground drainage.
