Fasten in single drywall

[M@ZE]

I am going to mount a central vacuum cleaner on an exterior wall as it is the only place to attach it. There are varying opinions on what is best, Molly bolts, drive anchors, rawlplugs, etc. It weighs 10.5kg. What do you recommend for attaching to single-layer drywall, with 2 attachment points 7cm apart width-wise and 2 more about 13cm below with the same width apart (like a rectangle)?

What would you use?

A larger board screwed into the studs.

I wouldn't attach it to just plaster!

Locate a stud in the wall and attach two of the screws to it, the other two with drywall anchors.

What I have read on different forums and so on suggests that plasterboard expanders, etc., can handle quite a few kilos, and if I had a stud, I would attach to it, so unfortunately:

10kg with 4 expander plugs should, according to what you read, hold, if it really matches how much weight an expander should handle.

 

[JoakimJohansson]

Yes, it should hold! But there aren't any vibrations or anything like that from it, right? Thinking about if it shakes the plaster apart

 

[M@ZE]

No, I don't think so, there will probably be a little vibration but ...

Becomes a lot of weight on a small area. Personally, I would cut away an area that is smaller than what you are going to put up, insert kortlingar, screw the drywall back, and then fill in the "damages" with spackling. Then you can distribute the weight over a much larger area and you won't have to worry about it collapsing.
