These rods are larger than my patio door rods that I bought at Wayfair.  Thought they could carry weight of 3 panels together.  But rods are oddly not as strong as the other rod.  The brackets are farther away from window as well which defeats the purpose of black out drapes as sun comes through, in the only way we could install the rod with one midpoint bracket to split sides of drapes to windows set.  Usually like red barrel but not so much for this rod.  Should have reordered the other drape I had. My faultmistake.
