I have a bathroom cabinet which weighs in at 14.5kg (empty).
The cabinet says that the screws should be "into material, not plaster board".
The problem is that the horizontal spacing between the screw holes in the cabinet is around 55cm, which is never going to match the space between the two uprights in a plasterboard wall.
I have considered using things like this which would easily take the weight (as they are rated for 100+kgs, and there will be four of them). Will I get away with this, or is there some bigger reason I'm missing why the cabinet says "not into plaster board"?
I have looked on all the information I can find on their website, and tried their Q&A, but no luck so far.
UPDATE: I have heard back from the company which makes the cabinet, and they usefully say (paraphrased) "We say don't mount on plasterboard because it's weak. But it'll probably be fine, all our publicity photographs are done on plasterboard".
