Also known as a waterspout or drain pipe, this vertical pipe carries rainwater from the gutter to the ground or drainage system.
-
Drop OutletItem Link
The fitting that connects the gutter to the downspout, allowing water to transition smoothly between the two.

Angled fitting that connects two gutter sections at a corner, creating a smooth directional transition.
-
Overflow DrainItem Link
A backup drainage system that handles excess water when standard downspouts are overwhelmed—common in heavy rain or clogs.

Parapet DrainItem Link
An opening through parapet walls on flat or low-slope roofs that directs water away from the structure via internal piping.

Rain ChainItem Link
A decorative and functional alternative to a traditional downspout that guides rainwater down in a cascading motion, reducing splashing.

The underside of a roof overhang connecting the fascia to the home’s exterior wall. It aids in attic ventilation and gives a finished appearance.

A sloped block placed beneath the downspout to channel water further away from the home’s foundation, preventing erosion.
Hidden Gutter Systems
