I'm in the process of trying to install this product, which is ruined by completely inadequate instructions.
For example, it begins by stating "mark and drill holes". What size? While it give the positions for the holes it give no indication of what size. 1/8"? 1/2"? Just so you know, I tried 1/8 and it split the screw holder, as I tried to "gently" pound it in, and ruined it. Since there aren't extra holders, the whole thing goes into the trash.
Back to the hardware store for a different brand. I'm sorry I bought this one.
By the way, the directions assume every screw goes into drywall. If you hit a stud, you're on your own since the provided screws won't work. It also gives no indication if this is removable without ruining the wall
