I would like to mount a wall shelf above a closet door in a small bedroom.
I was thinking about using the Ikea Ekby shelf, which is 59" long (exactly the length of the sliding doors of the closet). I don't know anything about how the wall is made and how to properly reinforce the shelf. (Ideally, even to hide the brackets completely.)
What is the best way to find out how these closets are made behind the drywall?
I have a magnetic studs detector and I know for sure that there are vertical metal studs on both sides of the closet. It looks like there's also a (wooden?) horizontal beam right above it.
What's the best way to properly fix the shelf?
