These rods were exactly what I was looking for.  I used them on a six foot patio door.  The curtains and then a valance on the front rod.  The rods are very sturdy and with the centre bracket it feels very strong. They snap in to the wall brackets quite easily and they do not feel flimsy.  I used room darkening curtains, so I could wrap the curtains around the end curve of the rod to the wall to block all light.  Great buy for the money.
