I think you are really asking for the minimum and maximum mounting heights for equipment to be accessed by someone in a wheelchair. These dimension depend on if the person can approach the device from the front or from the side while in the chair. From the guidelines: in a chair with front approach: 15" minimum, 48" maximum; in a chair with side approach: 9" minimum, 54" maximum. But please check these out. You can access the info at:
