Only one I could find long enough to extend our whole window with out piecing together a few. Seems sturdy enough but could be a little thicker as it feels a little flimsy for so many curtians. I should add i have 4 of the black out curtians that are very heavy. And I do worry if kids or pets pull on the curtians is the bar going to bend. So far all good. 2 years in and still good. No bend.
