Amerimax Home Products 85010 Flex Poly Downspout Extension

Product Description

The AMERIMAX HOME PRODUCTS 85010 is a flexible polyethylene downspout extension designed to direct roof runoff away from a structure's foundation. It connects to standard downspout outlets and stretches from a compact 24 inches up to 55 inches in length, allowing the installer to position the discharge point as needed without cutting or fabricating custom runs. The extension fits both 2-inch by 3-inch and 3-inch by 4-inch downspout profiles, covering the two most common residential gutter sizes. Roofers, gutter installers, and general contractors typically supply and install this component as part of a complete drainage system.

This extension is suited for residential applications where flexible routing is needed to clear landscaping, walkways, or grading obstacles. Because it collapses when not in use and extends on demand, it works well in freeze-thaw climates where a rigid splash block extension may shift or crack. It is commonly installed at grade level on the discharge end of a standard K-style or round downspout system. The white finish is a common match for painted aluminum and vinyl gutter systems on residential structures.

Key Features

• Fits 2 inches by 3 inches and 3 inches by 4 inches downspout openings

Compatibility

Designed as a direct-fit extension for residential downspouts measuring 2 inches by 3 inches or 3 inches by 4 inches, covering the most common K-style gutter downspout outlet sizes.

Installation Notes

Installation is typically performed by gutter installers or general contractors and requires no specialized tools. The extension should be seated firmly onto the downspout outlet and angled to direct water at least 4 to 6 feet from the foundation per common drainage best practices. Ensure the discharge end terminates on stable ground or a splash block to prevent soil erosion. No fasteners are required in most applications, though a sheet-metal screw or gutter-clip may be used to secure the collar if wind lift is a concern.
