Video Transcript for Buyers Products Flat Plate Cast Trailer Coupler Review

Hey everybody. Adam here, with etrailer. Today, we're gonna be taking a look at the buyers products flat plate trailer coupler. This thing's gonna be made of cast steel. So it's gonna be extra, extra strong and this is gonna have a 2-5/16 inch ball. You wanna make sure that the coupler is gonna match the ball on your trailer.

'Cause if it doesn't, it's not gonna work. So just make sure to do that. If you don't have some, we got some for you here at etrailer. One thing I think is real neat about this is it comes with a pin so you don't have to buy one separate, you go like this. But another thing about it, it's connected.

So I lose things all the time. When there's a cable connecting it, I'm not gonna lose it. So when you take this out, you don't have to lift this up. It's gonna be an auto latch feature, which is also pretty neat. There are some other auto latching feature or couplers that we have the easy latch, but that's just, it's just a little plastic piece.

I don't know. This is made of Cast steel. It's a lot more rugged and heavy duty than the other one. But as you lower it down, it's gonna push up and then we're good to go. I like that because it's just gonna give us one less step to hook up and then once we're done, obviously we connect our pin, but I really like that.

One thing, of course, you're gonna need with the coupler is the ball. So you wanna make sure to grab one that's gonna be just as VP as this if you plan on maxing this out, 'cause it does have a capacity of 18,000 pounds. So make sure that the ball nut that you're using and the ball is the right size and is rated the same or at least more. You just don't wanna limit your setup from the get go. In my opinion, this is definitely an upgrade from some of the easy latch couplers that you can have just because it's just more beefy. I love beef. I like when it's nice and heavy duty, especially on a big trailer like this, you wanna get the right stuff. And I think this is gonna be better than the other options that we have over on our website if you're looking for the quick easy latch couplers. When mounting this up, we are gonna have to source our own hardware and one measurement I want you guys to take before you order this is just on the flat plate of your trailer, just make sure it's gonna line up. So it's four and a half by four and a half. So just make sure it's gonna be the right size for you. It's pretty standard, but the diameter of the holes that we're gonna have to grab our own hardware for is 5/8 of an inch. So just make sure and grab the right size hardware that goes all the way through, but whatever you do plan on using what you want to do is you want to have a lock washer on the back and then a nut, just add that on. But we're not gonna really tighten these down all the way. I just like to get it going and then we can do the rest of our bolts. And that just about does it for our look at the buyer's products cast flat plate trailer coupler..

We use this coupler on all of our camper builds. The 4 bolt mounting plate allows customers to replace the hitch many years down the road but they likely won't need to because the simplicity and superior quality of this design. There are many great hitches at etrailer but this is our go to. etrailer has amazing customer service and they are always helpful.

See what our Experts say about this Buyers Products Flat Mount Trailer Coupler

  • Plate mount hitch
    That's a tough one. I have attached the couplers that I have that are designed to be plate mounted but they are all 4.5" center to center like part # 3370091558. They all offer the 2 5/16" ball but I can't find anything close to 3" x 7" mounting patterns. Is it possible that it is an older style that isn't produces any more? I don't know the exact application but if you can't fins anything to match can you drill mounting holes for one like these or is there interference?

  • Torque Spec to Mount Buyers Products Cast Trailer Coupler part # 3370091558
    I spoke with my contact at Buyers Products and they informed me that the the bolts that mount the Buyers Products Cast Trailer Coupler part # 3370091558 should be torqued to 225 ft lbs. The hardware should also be Grade 8. You may already have a torque wrench but if not our part # PT79FR is rated for up to 250 ft lbs and would work great to install this coupler.
