Which Way Does The Double Shower Curtain Hang Need A Pivot Shower/curtain Rod That Can Be Hung From Ceiling. Where Can I Find One?

Need a pivot shower/curtain rod that can be hung from ceiling. Where can I find one? - which way does the double shower curtain hang

I have a double cab, or 93 "wide. I do not want to drill holes in the ceiling to hang a bar - I have a pivot bar to hang from the ceiling, and each panel shower 45-50" wide. I hang the pivot rod to the ceiling. Any help?
