Fan tops are offered in a 3-1/2" tapered louver that freely rotates 360 degrees. Fan tops must be a perfect radius with the height being equal to the radius plus the width of the bottom rail. (i.e., if the width is 50" then the height would be 26-1/2" which is the radius of 25" plus the standard bottom rail width of 1-1/2".)

See chart below for rail sizes. Bottom louvers will spoke into bottom rail and will be fixed open or closed .
