Hopkins 47605 Flat 4-Wire Knockout Adapter Review

My husband installed this in the back of our RV because our new dog was constantly chewing on the hanging wire. That works great.

Not used yet. It looks like it should do what it's designed to do, but you'll need a mounting plate with a 1 1/4" hole or drill it yourself somewhere.

I used it to flush mount a trailer plug into a Smittybuilt bumper. The thickness of the metal made fitting a real pain, but for most traditional bumpers this wouldn't be a problem.

I used this to go through the bumper hole I made for my Jeep. So far it has withstood mud and snow well. It also withstands subsequent pressure washing. This was exactly the part I needed.

This product made unhitching my trailer very easy. Now I don't have to fiddle with a tiny flat fork anymore. I didn't have to worry about the wiring either as it just plugged into the factory spade connector. great product

I have ordered and used this product before and am very happy with it. That's why I didn't hesitate to order it again when I realized I needed another one. This is a great product that will give your trailer wiring harness a professional look rather than wires dangling from your vehicle. I actually used this on a Polaris RZR, not a car, so there are other uses, not just cars. Extremely easy to install. I couldn't be happier.
