Hand Towel Ring mounting blocked by duct
I am near completion of a bathroom upgrade. I was about to hang a hand towel ring to the wall when my stud finder reported a very wide stud area. I looked through my construction pictures of my house and found that there is a oval duct going up through the wall right where we want to mount the towel ring. Can I use a drywall anchor with sheet metal screw to attach this still or am I just SOL??
