I have the Rock's grommets too and they are a little tight. The silicone sleeves on the probes just fit through, a little lube or moisture can help.
The other brand referenced above might be easier to install, but unless it is significantly thinner brass tube material, it may not change the problem by too much. Also, to change it back you have to drill it out vs Rock's which you just unscrew.
Rob, does the guru grommet have a bigger ID than Rock's?
FWIW, for Rock's grommets you pop a screw out where you need the sensor to pass. Slip the brass tube into the hole, slide the collar over the tube and hold it together. Tighten the set screw in the collar to hold the pieces together. Don't overtighten or you will crush the sleeve making things harder to pass through.
The limit seems to really be that the hole in the WSM is only so big. If you want the grommet to still hold the inside parts together, you have to have a tube of some kind. Thus the dilemma.
I have one pit probe and two meat probes. It didn't occur to me when ordering that the two grommets I bought were one less than I really needed.
However, I'm not ordering any more of them since that would mean that the three sensor wires would all come out of separate holes. This can get rather tangled up due to short sensor cables.
I'm considering drilling a separate new hole and putting in some sort of gasketed bulkhead fitting to accept multiple wires. My first thought is a bulkhead pipe fitting with a silicone plug in it with a few holes. This would handle the temps and neaten things up a bit.
Hope that helps, I've been thinking about this topic for a while and your question just triggered a brain dump. </div></BLOCKQUOTE>
Thanks Pete. I think I understand how the Rock's grommet works now. Just to recap, though, the collar goes on the INSIDE of the barrel, right? And does the washer go on the inside or outside of the barrel? I ordered those Guru grommets last night, so we'll see how they work. I'm thinking about pulling the trigger on a 22.5" WSM, so I suspect I'll have a use for all of my grommets.
