Marcus on abuse. This kit redirects water away from the foundation when the primary downspout is blocked. It is designed specifically for 5-inch corner gutters.
When a heavy storm hits and your primary downspout is clogged with debris, water pools at the foundation. This 5-inch downspout diverter kit provides a secondary path to keep that water moving away from your home's base.
Look at the product photo to verify the 5-inch diameter fit and the corner configuration. Check the visual weight and material finish to ensure it can handle the volume without rusting or failing under pressure.
