I'm trying to hang curtains from near the ceiling. I have 5 brackets. 4 of them have successfully been screwed into wood, at least with the top screw (the bottom screw was as a wall anchor into drywall, because the wood runs near the top of the wall). However, in one location (2nd from the left-most), there is metal instead of wood covering the part I want to screw into. It is very likely the metal is from our air shaft for air conditioning so I probably shouldn't mess with it. In the end I opted just to use two very short screws which only reach into the drywall. Of course an anchor is also impossible because the metal is just beyond the drywall. So on the 2nd-left bracket the only thing supporting it are screws into drywall. I was hoping maybe the 1st and 3rd brackets will cover for it. But I'm not so sure about this, because the curtains will be really heavy (14 feet across, with heavy end finials and 4 curtains total). The distance between 1st and 3rd brackets is about 7 feet and spans two curtains total.
Will it help to drip superglue onto the 2nd bracket?
How about a hackneyed improvised apparatus where I find a super long metal strip that extends to either side wood studs, and screw that in, in such a way that it presses the top of the bracket into the wall?
Is there such thing as a "shallow wall anchor" that is only 3/8-inch long and doesn't have to poke beyond the dry-wall? Because immediately beyond the dry-wall is metal.
Do I even need this 2nd bracket? (There's 7 feet and two curtains between brackets 1 and 3)
