I use the holder with a Benq TH681.
For this Mounting screws were included.
However, there are 3 points that could be better in the set.
- The anchor which the set for ceiling mounting in are simply REFUSE. This I would trust only the weight of the holder in any way. Let alone the additional weight of the projector, including cable.
- Cable management is useful for when the cables come really as already mentioned in the ceiling paneling etc. If you are in an apartment or house depends like most the projector on a concrete floor and the cables with a cable duct to the projector performs useless.
- The last but not exactly terse error is the bracket which is hooked. Here there seems to be manufacturing tolerance. Taking these as can be seen with me in the images so mounts and tightening does not surprise me that is broken at one or the other of aluminum castings. Because then you have to 5mm on voltage put what in the long run can not really be good.
Solution are 2 washers. Unit price about 9 cents.
