Brushed Nickel Curtain Rods Where Can I Get Extra Long Curtain Rods?

Where can I get extra long curtain rods? - brushed nickel curtain rods

I am looking for extra long (up to 212 inches) of curtain rods, brushed nickel, preferably in color or something similar. I have tried to Primark, Sears, Bed Bath & Beyond, Restoration Hardware and Pottery Barn, but no luck. The longest they have is 144 cm with a bar extension of 40 inches for a total of 184 cm. Someone knows where I can have the longest bar?
