Hi - the rods are actually called 'Portieres'.... very old fashioned, but still just as effective!!
I've just ordered one for our back door this year - I got ours from here

I checked ebay & the usual places, but no joy - like I said, very old fashioned, but I'm sure we'll be using ours for a long time to come!
