Hello!
I am going to mount a bracket for a projector on a ceiling. The total weight will be about 20kg. The screw should be at least M12.
The picture shows what the ceiling looks like, I am quite sure that there is gypsum (drilled a small hole) after the "plate" 2-3cm in.
What is the best way to attach it securely and durably? What type of screw/plug, etc.?
Thanks in advance for the help. I hope I'm not completely off track.
Best regards
