Question about Electrolux Window kit

My window is 2.40 metres high, and it works with appropriate WE35 extensions.
Theoretically you can do it as long as you want, there is no direct limit.
(Officially I am above the limit that Electrolux states)

However, I have to say that the weight of the extension is already so high that the lock often opens due to the weight. That's why I don't recommend going over the 2-metre mark, it's annoying sometimes. But you could also just glue the lock on a little or something. That's probably why the official limit.

But my window is so damn big, I can't get around it ^^

together with WE35 should fit.
