Hi,I currently have a panel blind system above my patio door. I'm attempting my first DIY project to install curtains and have found the correct sized rod and end brackets but as the door length is 65inches, I think I need to install a supporting bracket in the middle. I have less than 2.5 inches clearance between window frame and ceiling for the middle bracket and the Ikea betydlig won't fit. Any advice on how to ensure the rod is supported would be much appreciated!Thanks!
