Gutterant 16.5ft Extendable Downspout Extension — 4-inch Diameter, Flexible Black

Overview

The gutterant 16.5ft extendable downspout extension is designed to move rainwater away from your home’s foundation and toward safe drainage areas. Its sleek black finish conceals neatly against most gutters while delivering practical performance during heavy rains or light showers. A thoughtfully routed downspout extension helps minimize splashback near doors and walkways, protecting landscaping and walkable surfaces without making bold guarantees.

Flexible, Extendable Design
