The movable barrier drive case can be configured and arranged to attach securely and non-temporarily to a movable barrier drive assembly. By these teachings, this movable barrier drive case can further comprise an installation safety latch (402) that is configured and arranged to securely and only temporarily maintain a selected disposition of the movable barrier drive case with respect to the mounting channel during installation of the movable barrier drive case. So configured, the installation safety latch can serve to maintain the movable barrier drive case in an installer's selected position with respect to the mounting channel during installation prior to using the clamp to non-temporarily attach the movable barrier drive case to the mounting channel.
