Hi all - my contractor installed an approximately 48-50" rod in my entryway closet. I think it's chrome, but not entirely sure. Anyway, after about a year, I've noticed that the rod is slightly bowed in the center. It doesn't seem to be a concerning amount, but would appreciate views on the photo and whether this looks concerning / should I add a center bracket to avoid future headaches. If I need to add a center support - any suggestions? Thanks for any thoughts!
