In this 1995 image, a young child who was seated in a wheelchair was operating a manual hand crank on a casement window. Because the crank was located on the window sill, which was no more then thirty-six inches above floor level, it not only facilitated ease of use for wheelchair-seated individuals, but very short people as well. Single or double hung windows, by comparison, require two hands, considerable force, and a long, high reach-range.
