Rod works great for curtains over our 12ft sliding door. We put two of the supporting pieces in the middle, and the one on either end of the rod (which might not be recommended per the hanging instructions but we needed to be able to open and close the curtains). The rod is actually a bunch of smaller rods that are screwed together - I actually think that this helps the rod be a bit sturdier, instead of one or two pieces that make the rod long. Overall very happy with the purchase.
