The Unico recommended here is interesting.

They have sloped outlets, 15 and 25 degrees for sloped ceilings and
walls.

Who has sloped walls?

Probably more than you think. I know of one house that has the second floor
rear wall sloped. Tutankhamun had the walls of his place sloped. I've seen
attic walls sloped. You have to get out more!
