Interesting method of installation. For anyone who buys this, there is a brace clip on the backside of each piece that gets drilled into the wall which you place the hanger on after. Use a laser level when mounting the brace clip into the wall so your bracket(s) is/are level. I personally used more screws than the recommended 2 per unit, I used 4 for full stability. The kit comes with drywall anchor screws but ideally you should drill the brackets into studs, at least the top and bottom screws per bracket. The one bar I didn't have a stud on one side and it's not as solidly secure as the side that's in the stud. You place the hardware on the bracket and there is a little screw hidden in the bottom that you screw in to tighten the bar to the brace.

I do like the hardware, it's pretty. Took a star off because the corners / corner edges could have been softened just a smidge.
