The adjustment is set----they put the 2 barre heights to accommodate different heights and depth of work. It does not have sliding adjustment. There's a VF thread on barre comparisons that has input on this barre from other VFers. HTH
I have it and no, it's not adjustable. But it's constructed with two horizontal bars so one will probably be fine for you.
