What's this?

[88v8]

I'm changing the chimney pot for an older one. The top diameter is bigger, so I need one of these with a bigger diameter 'skirt'. As you can see, it's stainless and fits inside the 6" flue pipe.
Can't find one for sale, but it might help if I knew what it's called.

On top of it there's a separate clamp-on terminal.

What do the chimney serve? Open fire? Gas fire?

Is the 6" flue goes all the way down ?

You could ask metalwork shop to make circular stainless steel big enough to cover chimney pot with a hole for existing cowl to go back in.

Woodburner installed by a HETAS installer. Yes, the flue goes all the way down. The top 2ft or so inside the chimney is solid, the rest of it is twinwall stainless flexible.

Yes, I suppose I could get a larger diameter stainless skirt made to sit under the existing skirt, but it's another joint for the wind to blow water through. Was hoping just to find a larger diameter skirt fitting, if that's what it's called.

Thankyou. Now I know what I'm looking for.
Oddly enough though, 15 mins Googling and I'm not seeing any attached to a flue insert. Only separate versions, like the sort of collar that's put on a dog to stop it scratching itself.
Any idea who might sell them?

They can weld it together. Weld around the joint to make it one piece and watertight.
