The frame assembly ( 16 ) includes an extruded aluminum top rail ( 22 ), an extruded aluminum bottom rail ( 24 ), and a pair of extruded aluminum side rails ( 26 ) connecting the top and bottom rails ( 22, 24 ). The top, bottom, and side rails ( 22, 24, 26 ) are joined to define the rectangular shape.
