If you need a rod that falls into one of these ranges, you will buy two identical rods and combine them to create a continuous drape rod with a single seam in the middle.
Again, you need to buy two identical rods. Use the two thicker outer parts and one thin part from one of the rods and a single thick outer part from the other.
You will need one 240″ long rod and one 144″ long rod. You will use the all of the outer thicker parts to combine into one extra long and continuous drape rod.
