I need the ceiling mount for ACER H6510BD. Watching You - although just how it is. You have to push back the retaining fingers completely to fit for inclusion in the projector housing nuts. Here I would have had a corresponding additional description expected, since the holder is yes advertised specifically for this projector. In the solution of the riddle, as for now the holding fingers must be positioned, I had of course a few times the fingers move back and forth. In this case, a large slab of the coating is flaked off at one point.
Otherwise, the bracket is very stable, fixing material is attending. I've needed in the shortest version, so I can not comment on the extension rod. The accompanying description is, however, sufficient for the assembly of the holder.
1 star deduction for the coating defect and the missing note for mounting on the projector
