I bought a set of 2" grommets and after drilling the recommended 2" holes in my desk the grommets fit really snugly. I would recommend a 1-15/16" or even 1-7/8" hole for a tight fit. The grommets are basically useless to my business now, I bought them to keep your cables smooth and now I have cheap grommets that don't stay as flush as they should. If the seller had mentioned the need for a smaller hole I would have been much happier with my purchase.
