Turns out it wasn't easy to find a replacement clothes rail. I emailed Ikea & they don't sell a replacement rail because it doesn't have an item number. So we searched online & found something similar but it was $20 & maybe wouldn't even work. We looked at local hardware stores & couldn't really find anything that would do. Of course we could have just drilled new holes & hung any regular old clothes rail but since there are no doors on our wardrobe, I didn't want 14 different holes visible.
Last week we went to Ikea again & while we were there thought we'd check out their wardrobes. We wrote down the item numbers of a couple different wardrobes that used similar clothes rails & crossed our fingers that they would be available for purchase separately. Luckily for us, one of the wardrobes had almost the exact rail that we needed sold separately for $10. It was a little bit long so we trimmed it with the saw.
& this week, finally got it mounted in our wardrobe...
