Product review (5 stars): Perfect fit!
These are perfect. They replaced old cartridges that we had which were an older style that were mounted in such a way that there was an elevated rim all the way around the edge. We basically could not use our larger pots and pans on the old style cartridges because the cookware would rest upon the rim instead of making contact with the heating surface! These newer cartridges are completely flush mount, so we are finally able to use all our pots and pans without having to replace the whole range!
