Can you make it up with a couple of 15° and 30° single socket bends instead of that adjustable 135? They’re not the best things in the world, especially when so close to the surface, as the knuckles are huge.

Existing run is at some fancy angle, adjustable would give freedom to match it.

But that made me think and I should go for round gully, then I can align is as I wish and even 1 fixed bend will do! Unless the top on square one spins?

The "top" is usually a separate item which you cut to length, and the trap / gulley sits where it needs to go.

id cut it per the photo then clay to plastic collar and whatever bend you need, there will be some give in the collar as well so easy enough to get it where you want. then haunch it in place with lean mix.
