CURT 57240 7-Way RV Blade Vehicle-Side to 🔌 4-Way Flat Trailer Wiring Adapter: Versatile Trailer Connection Solution Review

Everything worked and was pretty easy to install. Very strong hold. Love the fact that the hitch can be fitted for both low and high trailers and comes with a couple of balls. Installed in my car without any modifications.

Why pay more? This adapter is well made, works great and is made by well-known manufacturer Curt. I have purchased a variety of Curt clutches and cable sets over the years and have never had any issues with fit, functionality or quality.

Loved this adapter, went through 4 other red adapters that plug in from the inside rendering the adapter useless. This one doesn't light up when plugged in, but you know it works every time you plug it in. Great adapter, highly recommend.

I was a bit nervous about the low price but I use it for a small trailer and so far it's been fine. No moving parts so I shouldn't be surprised. For the price we paid it was more than worth it. It fits well with the plug installed on our vehicle and provides a secure connection. Very happy with this simple adapter.

I had to hitch up my UTV for service but my GMC Sierra 2500 has a 7 blade linkage built into my horse trailer. Locally available 4-way flat adapters are $17-$20 so I checked out the Revain and found it for under $4 and it was delivered next day which was an added bonus. Based on the reviews I was wondering how well it would fit so I was delighted when it fitted perfectly.

My kids left my other one in the grass and my garden tractor broke it into small pieces so I had to buy another one. My last one was red plastic and caught fire when used. Neat and useless, but no real benefit from this feature. It's a hard rubber and quite durable. The finger grip makes it easy to disconnect from the stacker. If my kids keep this one and it gets destroyed too, I'll buy another one.

I bought this to make my Silverado's 7 pin connector compatible with the 4 pin connector of a trailer I bought. It fits but wobbles, and even with tape wrapped around it, there's still enough movement to cause occasional connectivity issues and the bulbs flicker. I know the connection point on the truck isn't a problem because the person who sold me the trailer had another similar adapter that fitted just right.

The price was good but unfortunately the quality is not as good as it could be. There is usually only one set screw holding the end cap to the chassis. This is usually enough to keep it in place. But on this device, the plastic housing is a bit looser, so when I unplug this device from my pickup truck, the end of the connector is still plugged into the truck's receiver, while the body of the connector slides over the cable. Correct this deficiency and this plug will be perfect.
