Common materials for downspout accessories include rubber, polyethylene, polypropylene, and aluminum.

Some extenders include a clear or mesh debris screen at the inlet to block leaves and make inspection or cleaning easier.

Adapters and inlet ports are described to fit common sizes such as 2×3 inches, 3×3 inches, and 3×4 inches. Some outlets are also shown connecting to 4‑inch PVC or corrugated pipes.

Flexible extenders are listed to extend from about 22 inches up to about 63 inches.

Several items list a 1 Year Limited Warranty in their product details.
