A movable transparent panel for reconfigurable office partitions and the like is adapted for floor-to-ceiling applications which include a floor track shaped to be supported on a floor surface, and a ceiling track shaped to be supported on a ceiling surface. A panel frame is supported in a normally vertical orientation between the floor track and the ceiling track. The panel frame has vertically spaced-apart upper and lower horizontal members with a pair of vertical side members interconnecting the upper and lower horizontal members and extending therebetween to define a generally quadrilateral opening. The upper horizontal member is operably connected to the ceiling track, and the lower horizontal member is operably connected with the floor track. A substantially transparent sheet is removably connected to the frame and extends across at least the portion of the opening. A vertically adjustable support retains the frame at a selected height above the floor track to permit height adjustment and leveling of the frame to account for variations in the floor surface.
