Hmmmm... MINE's a 504 - I could be wrong but I think the column is the same (!) with the same configuration. I remember being able to separate the floor standing base from the table/column thereby allowing conversion to a wall mount unit. I THINK that 5108 is similar.... as long as you don't separate the column from the table - that's the crucial thing - as far as I know. But you may NEED to separate at least the base to get it through your door(s)!
