ABSTRACT:
A rotating window mounted directly to one side of a stationary, viewing window or panel without the need to cut a hole in the stationary window. The rotating window faces toward the working or weather-exposed area and slings off any water or other debris that contacts the rotating window to maintain clear visibility through the stationary window. The rotating window further comprises a means for drawing air through the area in between the rotating window and the viewing window so that moisture does not collect on and fog up either window.
