A removable mullion comprising: a first tube; a second tube in telescoping arrangement with the first tube, the first tube and the second tube being adjustable between an extended position having a first length, and a retracted position having a second length less than the first length; a biasing member connected to each of the first tube and the second tube to bias the first tube outward from the second tube towards the extended position; a guide rod attached to the first tube and extending through an interior section of the first tube and the second tube; and a locking mechanism positioned within the second tube adjacent to the guide rod, the locking mechanism being adjustable between a locked orientation that extends into the interior section of the second tube to block movement of the guide rod and prevent movement from the extended position to the retracted position, and an unlocked orientation that is positioned away from interior section of the second tube to provide movement from the extended position to the retracted position.
