Review on 🔌 7Trees Electrical Grommet Firewall Set by Maxwell Thomas

I used these to replace some of the rubber bushings that protect the wiring on my jeep. I found out they were plugs and had to cut the middle out of some of them and I was able to adjust them to what I needed. If you're just using them to poke some random holes in sheet metal, they should work great. Not very thick but they will do the job and you will get them in many different sizes.
