Bath board for bathtub - Price reduced

I bought this to install in my home bathtub, but I forgot about it after moving and put it in storage.
It is unused, but the box is slightly dirty.
That's why I've listed it as Used - Like New.
Photos 10 and 11 show the maximum and minimum adjustments.
It can be used as a stand for items like TVs or books in the bathroom.
