It's Great but, the instructions say to use a 9/16" bit but, you can't buy a 9/16"Masonry bit, they only have 1/2" and the next size it 5/8" then 3/4". I had to use the 1/2" masonry bit and wallow it out, to make it work.
So maybe you use a 1/2" type mounting bolt, it would still be plenty big enough.
