Included are several bolt sizes with 4 screws for various projectors and 4 arms where the holder is attached to the projector. In my Benq W1070 I needed only 3 arms and 3 screws. The mounting on the ceiling was made with the self tapping screws provided, the dowel I do not need, because I have a false ceiling made of wood. At first I thought that it would perhaps not hold true since my wood panels are not very thick (like laminate). But that was no problem, the mount holds bombproof.
The support I have put on the table and aligned with a spirit level, then the screw screwed tightly. So you have the projector immediately aligned properly and it will be easier because the alignment overhead is too sluggish.
When Benq W1070 I reached the mount and lens shift a distance from ceiling to top of image 40 cm in a Entferung of 280 cm. That is the maximum lens shift downwards.
Positives:
- Quick assembly / assembly
- Many screws here for different projector
- Robust
- Many settings
- Good workmanship
Negatives:
- Nothing
