I have a DCS CT365 5 burner drop in cooktop, bought ~2008 or so.  The rubber bumpers on the bottom of the grates finally broke and DCS told me that since it is a discontinued product, I would have to purchase brand new cast iron grates!  Ridiculous!  So I took the chance and ordered these, figuring if the stem was too big to fit in the hole in the grate, I could shave/cut off to make it fit.  Luckily they drop in perfectly--a little bit of high-temp silicone and my grates are good to go back on (unfortunately the cooktop got scratched up beforehand...)
