A wall panel of a moveable and demountable wall panel system that is secured between a floor of a room and a ceiling rail secured to a ceiling of the room, the wall panel comprising:

• a frameless panel having a top, a bottom, a left side, a right side, a front, and a back, the frameless panel defining a top portion toward the top and a bottom portion toward the bottom of the frameless panel;
• an upper clamp assembly secured to the front and the back of the frameless panel at the top portion of the frameless panel;
• a ceiling track extending in a lengthwise direction between the right and left sides of the frameless panel along the top of the frameless panel, the ceiling track being secured to the upper clamp assembly and configured to be removably inserted into the ceiling rail, the ceiling track defining a pair of longitudinal grooves for slidably receiving a corresponding pair of projecting elements of the ceiling rail;
• a lower clamp assembly secured to the front and the back of the frameless panel at the bottom portion of the frameless panel such that the clamp assembly is configured to support the weight of the frameless panel;
• and
• a first adjustment mechanism secured to the lower clamp assembly and configured to expand or contract in height to selectively raise or lower the frameless panel upon actuation of the first adjustment mechanism.
