I need the same size but larger hole in the knob.

Hello, Debbie. I'm sorry to say that we don't have an alternate version of our 39-115. That said, I'd be happy to look into it for you. Can you confirm the exact diameter of the hole? We will need that to research our options.

We were able to tighten the screws on mine ant hopefully it will hold up
