Gas hob cut out width.

[David Foster]

Hi, I need to order a new gas hob in a granite worktop. The width of the granite cut out is 557mm and the bump on the underside of the old Belling hob is 550mm. Almost all of the new hobs state a cut out of 560mm wide.
What is the size of the underside bump in these hobs asking for a 560mm hole please? I'm hoping they are still 550mm and the cut out has a 10mm tolerance.

Would this work if you’re struggling? https://www.johnlewis.com/miele-km2...paGX5-u6bYtdhY0As4BoCeEsQAvD_BwE&gclsrc=aw.ds

I reckon you'll be OK: there is usually a bit of tolerance.

If you buy from e.g. Screwfix (or indeed, probably John Lewis!) you can return the item hassle-free if neatly repackaged should it prove necessary.

Yes, I must have browsed every single one and the manufacturers sites as well. I have found a couple of 550mm ones but we are talking wife wanting a black glass one

One of the reasons RGIs wont swap hobs, the cut outs are all different, I personally wont do them anymore , they can turn into a total nightmare

I have to order installation with the order, they say guarantee etc it fits, this could be a nightmare. They only ask that the zones are okay and the top width.

Ordered a Rangemaster, see how it goes, thanks.
