I was so pleased to find an adjustable rod for a Bay window and after reading all reviews, decided to order it.  This rod is so versatile in that it accommodates a range of measurements and angles. I read it was hard to figure out but I seriously did not look at the instructions. I laid the pieces out on the floor of the bay and could see how in went. I love the way the rod wraps into the wall and the angles are perfect. I highly recommend this rod for those odd angled and odd sized bays. It is substantial and solid. Be careful as there are a different sized actual rods. I got the thicker rod.
