3/4" hole?

Ach. I read this through three times and still didn't visualize it accurately.

I wasn't criticizing your post -you went on to explain further that probes aren't the same thing. I just wanted to make sure no one snipped off their probe too hastily without reading in full.

Yup! Not chopping off any probe ends.

Similar to the equipment your planning on they make other grommets which slide and rotate so the opening is adjusted down to just the size of your cable
Example:

You might try something like this if you want to go the grommet route.
