Mount fits Benq W1070 perfect. The scope of supply is neat, there are a lot of screws in different lengths there. Only this metal dowel screws, well, sometimes it's me own fault ... I could curse ... :-) eventually I took normal dowel and drilled new holes in the bracket and it's all perfect. What is still a bit unfortunate (but was also mentioned in the description) that you can not extend the bracket. So the distance to the ceiling. Would be nice if you could buy as an extra extension tubes.
