Cooker Hood Stud

Hi all

In process of installing a cooker hood and there is a vertical stud right in the centre line.

I have around 100mm either side of the stud which is not enough for the 125mm hole I was going to make for ducting.

Apart from drilling through stud (which is not ideal as this is what hood is attached to), only thing I can think of is to get an adapter to convert to rectangular ducting and pivot 90 degrees.

Thanks

A way around it may involve a bit of wall butchering. Cut a hole to reveal the stud and chop out a section for the duct pipe. Then add thicker shaped timber on either side of the stud to reinforce it and to allow the ducting through the opening formed. Make good with a plasterboard patch. You would need a multitool to plunge cut the stud.

Use 100mm vent

Thanks for the replies.

It's quite a large (90cm oven) cooker hood, so was worried 100mm would be too small. It recommends 150mm, although comes with an adapter down to 125mm.
It would be minimal ducting though (<1m), so I guess 100mm with rigid ducting and one 90 degree might be better than using flexible ducting to try and get around the stud.

I'm not too keen on the idea of cutting through the stud - there's various layers of insulation/chipboard which wouldn't be fun to cut back.

not sure i fully understand but look at " flat channel ducting " random example here

Yeah, one of the options was to use flat channel ducting - but it would have to go through the wall vertically to get through the gap, which would mean quite a bend in the ducting
