Rubber Grommet for 1-1/4 Hole - P/N 2035-3 Pack

I built a solar power plant. I submitted plans and pulled a permit to build and I needed it to pass inspection. Of course, when you build something to NEC code there's always those little details you can't overlook because the inspector will nail you on it. In my case, I was joining two components together where their 1.25 inch knockouts lined up together. That's what you want but in such cases, you have to put in a grommet to prevent the wires passing through the knockouts from chafing over time. It's a very small detail but the grommet is required. These P/N 2035 grommets were the perfect solution. It comes in a three pack but I only need one. The price of a re-inspection here if my power plant had failed over such a small detail is $90. The money was well spent on this product.
