I do not understand well with the photograph, but the screw hole is too big to use at all. It seems to be usable if fixed with all screws or anchors, but can not be fixed with ordinary screws. It was trial buying, but 4 pieces are probably useless. I think that there are not many people using such a band. If it is small, you can make it big, but if it is too big you can fix it if washer is used, but I do not have such a big thing. I was disappointed.
