Hello, I just moved places and wanted to hang my new curtians. But when I hanged them, the rails was already bending a ton. How can I stiffen/strengthen the rail without drilling in the roof?I tried drilling in to it but I only could come about 3 á 5 mm deep....How can I make the rail(??) Stiffer? https://ift.tt/2JNozes via /r/DIY https://ift.tt/2uZAT5S
