Mount coat rack in three layers of drywall

[p1r]

Hello.
I have a hat rack (standard model) that I want to attach to the wall in the hallway with four screws.

The problem is that the wall consists of three (four) layers of drywall, about 48 mm thick, then air.

In other words, Mollys are not entirely easy to use.

Has anyone encountered this and how do you solve it?

Best regards,
Petter

Are you sure it is plaster? It's not a plastered wooden wall or something similar? When was the house built?

There is Molly for triple gypsum, that should work or what do you mean?

Yes, quite sure.
Drilled holes and checked.
The house was built this year.

Well, I've searched. But can't find any molly with a grip range of 48 mm....

48mm? :x

Then it's not plasterboard, is it? Plasterboards are 13mm, right? -> 39mm

It may be that there is an extreme fire rating on the wall, which is why three layers of 15 gypsum have been used. For example, if it is an apartment-separating wall in gypsum, which is otherwise quite unusual in new construction. However, if this is a single-family house, it is very strange.

Should be enough with a proper plugg.

48mm? :x

Then it's probably not gypsum? Gypsum boards are probably 13mm? -> 39mm

ok, my mistake. Maybe not three boards, but 46-48 mm gypsum anyway. a bit hard to measure to the millimeter.

It might be that the wall has an extreme fire rating, which is why they've used 3 sheets of 15 gypsum. For example, if it's a partition wall in gypsum which is otherwise quite unusual in new constructions. If this is a single-family house, it is however very strange.

Ah, it is actually the wall towards the neighbor, it's about townhouses. Then it sounds quite likely that it's as you say regarding fire rating...

Ah, it's actually the wall toward the neighbor, it's about terraced houses.
Then it sounds quite likely that it's as you say regarding the fire class...

Yes, that's probably it. Depending on how much weight you're putting on the shelf, it should work with a slightly heavier duty plug.

Fischer does have up to 50mm, the question is who sells them,

Snap toggle should work excellently.
