Review on 🔌 Morris 22396 Plastic Knockout 10 Pack: Reliable and Durable Electrical Conduit Punch-outs by Mark Bennett

I bought these to fit the half inch hole on the inside of the tailgate of my new truck. I've read that this hole is used when using a bed extension, but I didn't have to drop small screws and debris into the tailgate. This allows me to keep it private but still access it if I ever use the specified extender. For those reviewers who want to complain that this isn't a "trade size" 1/2. You actually read the description, it doesn't say it is. This is for a 1/2 inch hole. If you want to buy a 1/2" plug, use 7/8".
