Thanks. The installation instructions only ask for an additional total 1/8" beyond the width of the cooktop, so I'm guessing this should be fine. I was also worried about the stress/pressure points on the granite from the two screws sticking out from the sides of the cooktop and constantly pressing against the stone causing a crack, but hopefully all should be ok.

Thank you!!

I don't like it wedged in, but I doubt any harm will come.

I see two granite fabrication solutions beyond doing nothing more:

(a) Have a competent granite fabricator cut out another quarter of an inch. This would require sealing off the kitchen, sealing every aperture, door edge, refrigerator cooling air path etc. against dust, and any exposed drawer sliders and door hinges below the cooktop taped off. Then a major kitchen cleaning to remove all dust.

(b) Remove the cooktop and use a set of diamond drills (not as expensive as they might be perceived to be) to relieve some of the granite where the screw heads are. Because this involves water, the dust might be contained, but the water flying about will have to be contained and the cabinet surfaces underneath protected.

Nether of these approaches is particularly appealing.

Depending on the function of the screws, a lower profile screw might be used to replace the ones that scrape on the granite.

Overall, however, the stress on the granite may be slight, given that the unit slid in relatively easily, and the susceptibility of the granite to cracking will greatly depend on whether the granite is already structurally fragile (Piracema white comes to mind) or very tightly bonded (NH granite typically used for curbing).

I enlarge granite and estone cutouts in homes regularly and never "seal off the kitchen...." I use a Festool rail saw with a diamond blade and vacuum, making several passes. The trick is on the second pass, you leave about 1/8" of stone to cut through on the last pass. Not cutting through all the way initially forces virtually all the dust into the vacuum. Cutting through an 1/8" of stone doesn't make much dust. Throw a cover over the cutout while cutting the last pass and virtually no dust escapes.

Good to learn of this capability. Thanks.
