I am working on electrical, and pulled my wires through the front firewall. It needs a grommet. The manual says to install the grommet. I measured the hole at 1 7/8”.

I can’t find that grommet. It isn’t listed on the packing list (at least that I can find). Ace Hardware, my local electrical supply, Home Depot and Autozone all couldn’t sell me one.

Is that grommet hidden in plain sight? I can’t find it!
