I have a projector that with it's mount, weighs about 3KG. There is only one place I can put it because of the way the wall is in my place and yup, there is no joist where I want to put it.
On the part of the mount you screw to the ceiling, there is a screw hole at each corner and one in between
The drywall is 20mm thick so I'm wondering, would this be enough to hold the lot in place and not have to worry about it caving through or what are my options? It's rented accomm so I can't go crazy. Maybe extend a flat piece of wood from one joist to another covering this area?
Any feedback appreciated
