Well The install of the box is poor and so is the Seal tight connector not threaded in all the way.
Randy's right about the little ears that come in the package of the box. The ear get screwed into the box from the outside and then those ears get screwed to the mounting surface. I don't like the ears because I thinks they're flimsy. I drill 2 small holes and use a #12 screw through the box with silicone. I silicone the threaded KO fillers too.
