A mullion assembly that is removably positioned within an opening. The invention includes a tube having telescoping members that fit together and are adjustable between a variety of lengths. The ends of the tube mount to first and second edges of the opening. A biasing mechanism positioned within the tube provides for adjusting the overall length of the tube. In one embodiment, a locking mechanism is located within the tube to prevent the telescoping members from moving relative to each other thus preventing the tube from being reduced in length and removed from first and second mounting assemblies and removed from the opening.
