I just went through the same thing. I got so annoyed at the full metal bracket. I ended up going to Home Depot and bought two metal shelf brackets that on side is 8 inches and the other 10 inches. I mounted the 8 inch side to the wall and the 150 sits perfectly on the 10 inch side. Not sure of your room decor but mine has dark walls, etc. so the black brackets blend right in. They have white and silver also. The best part is that they were a little over a dollar each.
