The Wall King system is adjustable down to 6 feet when mounted at it's optimal height.
The Roof King can be set to it's lowest position (although it's not adjustable). The lowest position is dictated by the roof height.
If there is a gutter, the lowest height you can get the rim to is 7 inches above the top of the gutter.
If you do not have a gutter you can lower it below the roof line ... rim height = 1 foot below the roof line. For example, if you have an 7 foot roofline without gutter you can set the rim to as low as 6 foot. After your player graduates to a 10 foot rim you can raise it one time.
