Fitting extractor grill from inside

[timhoward]

This isn't very electrical, but never mind!
I'm adding an extractor fan to a bathroom in a 4th floor flat.
The builder has helpfully cored a hole for me (110mm)
In the past I've used the Manrose Internal fit wall kit which works brilliantly IF you know in advance and core a 117mm hole.

In this case there's already an 110mm hole. Ever the optimist I tried one anyway and there is no way on earth it's going through.

Getting to the point, has anyone tried the Xpelair version as it looks to use a normal 4 inch duct pipe plus a folding vent and it would seem to have a much greater chance of working in this situation?

Are there any other products worth knowing about for this situation?
TIA

Do you mean like the one in #1

Poor Mike, everyone is asking him that!
He’s right, and talking about a further option/design that wasn’t originally mentioned.

If you care to read the whole thread, you’ll spot that has already been pointed out.
eg #15 !!

If anyone cares to read post #10 the one Mike referred to is not the same as the one in post #1.

I've found it helpful that this thread has highlighted several products for this situation, some of which I didn't know about.
Thanks to everyone for your help.

I think it's time to stop getting bogged down with the order it all unfolded now. Let's stop!
