I am not sure about the model 4400. Is it of the double leg construction like the 4800 or is it of single leg construction? I found one of their heavier single leg tripods with the double extension geared center shaft and the geared head that supposedly weighs 12.4 lbs. So I would guess somewhere around that weight. Most Majestics are rock solid and heavy.
That is what they call their double leg design and it would probably be heavier then the one that I mentioned. I would imagine with head that this will top 15 lbs., maybe a couple above that. It will hold most anything that you want to set on it.
