This adapter joins a 3 in. x 4 in. downspout to a 4 in. corrugated pipe. It is part of the FLEX-Drain system, a drainage solution that is compatible with virtually all traditional 3 in. and 4 in. corrugated pipe and 4 in. PVC.
FLEX-Drain is flexible, bendable and expandable. It bends around obstacles and holds its shape during installation. Its integrated soil-tight fittings lock with a simple snap and stay connected during back-filling. Taping joints is not necessary.
The system is made with no-break copolymers and exceeds all applicable ASTM crush standards.
