I think you probably want a right-draw traverse rod. Try continentalwindowfashions.com. for them. They have both the traditional white metal ones and decorative ones that look like the wood or metal pole rods.

Yes, you will need at least one support for that span. Traverse rods allow for that because of the way the carriers function. Your drapery will have to have pins in the top to hook into the carriers, but I am guessing if you are doing sheers you will easily find them with pleated tops, into which the drapery pins go very easily.

That's exactly what I was looking for! I love the wooden ones. I'm going to get the 2' Smooth Mohogany poles with the pass-through brackets.

Thank you les917!

If you're using light fabric and at least a 1 1/2" diameter rod, you can go without the center support. I have such a setup on my 72" slider with and it extends 12" on each end.

It has been 4 years now and still no sagging.
