Has anyone fitted an induction hob into a quartz worktop. I've bought a bosch induction hob and cant figure out how it is fixed to the worktop. The hob comes with rails that are screwed into the side of the appature that is cut in the worktop and then the hob clicks into the rail. I dont think you can screw into quartz and the instruction states not to stick the hob down? It's a bosch PXY875KW1E if that helps.
