Great replacement plug with great instructions. Cheap hardware.

This plug is a solid replacement, although I would have appreciated a 90-degree version. The instructions provided were really helpful. It easily accommodated my 50A cable with 6 AWG wires and an 8 AWG ground wire. Just a heads-up: the screws for clamping the wires require a lot of torque and are made of a softer metal, so they can strip easily, even with a perfect Phillips screwdriver. Using a flat-head screwdriver can be even more problematic. So, just be cautious and make sure to use the right size screwdriver.

Great camper plug

The plug I got was exactly what I ordered and it works well. I only had to make a minor adjustment by enlarging the hole to fit my 50 amp power cord, but once that was done, it worked perfectly.

Great value for the money.

This is a great cost-effective solution for converting a 30 amp to a 50 amp adapter for your RV. I used it to replace the end of my 50 amp RV cord, and it worked perfectly.

Cover slips with installation guide

One thing to watch out for with this unit is that the yellow cover can twist the internal plug when you're turning it to lock it into the socket.

As advertised, it's a great option versus purchasing a new cord.

You have to make the hole bigger for 50 amp cord

This is a heavy-duty, well-made item. I gave it four stars only because you need to enlarge the hole to fit a 50-amp cord through the yellow part.

Assembly was a bit challenging, but it works

I found one of the screws to be stripped from the plastic housing, likely due to assembly, but despite that, the product seems to be of nice quality and it works just fine.

Works, but yellow part doesn't fit over 50 amp cord

The plug does its job effectively, but I encountered a snag with the yellow seal component. It simply wouldn't accommodate my 50 amp cord, requiring some improvisation on my part to ensure a secure connection.

Workers Fine

I used this to create a 50 to 30 amp adapter for my generator's 30 amp plug to use with our RV. It's heavy duty and features a locking ring that secures it to the RV receptacle. It also worked great on my 5th wheel trailer after the original cord got damaged.

Great value and excellent quality

This replacement part is a fantastic find, great quality and functions just like the original equipment. It was easy to install on the power cord, and the color coding makes it foolproof. If I need another one in the future, I'll stick with this brand and part. It fits my trailer's 50-amp twist-lock plug perfectly, just like the OEM version.
