Our standard traditional half round dormer is available in 24", 36" and 48" widths, in roof pitches of 3 to 18".
It features a half circle shape, making it's height, half of it's width.

All parts are soldered when possible. When not, they are riveted and sealed (for materials such as aluminum and steel).
The louver portion features a stainless steel bug screen on its back side.
