So this is how to install an overhead bin. First, you are going to want to look at the how to install a shelf tutorial and that will get you to this point. You’ll see these end bells are slightly higher, slightly longer with screws up at the top as well. You are going to want to take these screws out a little bit so that the bin top has somewhere to set. You are going to take this top like this, there’s two grooves on that side (on both sides), you’re going to set the back in first and then the front just sets right here. You then take your screwdriver, secure these screws and you have your overhead bin.
