Hi
If you haven,t got a tube for the rod,go into your nearest carpet/floor supplier and ask them have they any empty trims tube and ask for the most wide 1 they have,these are normally 8 feet so you can cut them to size and please recycle the rest as it is cardboard,they might even have the stoppers for the ends of the tubes,ask for these too,for the top and bottom of your parcel,tape well each end... write the name,addy and write fragile a few times on it (if nothing else this looks well

)
Pop into your local post office and send recorded delivery..
Away goes your rod,securely..!! hopefully..
Hope this helps

PS,carpet grippers and wooden floor edging,s come in the "trims tubes"
