This worked really well...no worries about crimped probe wires, easy access for multiple probes all in 1 eyelet and it seals snugly.
I bought a 1/2 inch conduit nipple, 1/2 conduit nut, and a sealing cork 3/4 x 37/64.
This will work on any smoker except ceramic cookers, i know WSM folks had concern on running probes in with out crimping the wires. I drilled a 3/4 hole with a step bit and just widened it out a tad...the nipple fit right in. Total cost- $3
Run your probe wires through
.. sealed up
corked sealed up the hole
