1. CURT 25328 Channel-Mount Adjustable Trailer Coupler

Highlighted Features

  • Made of cast steel with black carbide powder coating
  • Mounts on a vertical channel bracket
  • Not suitable for channels over 2-5/16" diameter
  • Adjustable height
  • Latch system for easy locking

CURT 25328 Channel-Mount Adjustable Trailer CouplerCURT is a prestigious manufacturer of customized trailer hitch receivers,  cargo management systems, weight distribution hitches, trailer brake controllers, ball mounts, and so on. Their heavy-duty towing components turn your car into a much capable replacement of a truck that surprisingly gets the job done.

On top of that, you can easily adjust it upwards or downwards to level the towing. This feature makes balancing the weight between your ride and the trailer so easily. What we like about the product is its adaptability with a broad range of trailers. Trailer balls with a 2-5/16-inch diameter are compatible with the 25328 coupler. 

It is compatible with #48610 and #48650 CURT channels. But truth be told, its height adjustment option was a highly sought-after feature among professional tow truck operators. However, you might need to buy lock washers and ⅝”×5″ bolts because the package doesn’t include these mounting tools.

The latch flaunts an easy-lock mechanism, which helps the coupler to ensure a tight fit. After all, a coupler hanging loosely from the trailer ball not only is risky but also blows an overall balance out of proportion.

Up next, we have its material quality to discuss. The trailer coupler is made of sturdy cast steel. On top of that, it is finished with a premium black carbide powder coating. It makes carrying a total of 15,000 pounds of trailer weight and 2,250 pounds of tongue-weight much easier. Moreover, the corrosion-resistant materials withstand the elements- grime, rain, snow, dirt, and more!

CURT’s very own A-frame 25227 coupler will fit all standard 2-5/16-inch diameter trailer balls and mount an A-frame tongue. It is a no-brainer and an incredibly safe choice for a trailer coupler.

The key aspect to consider when loading your trailer is undoubtedly weight distribution. Higher weight at the trailer’s rear part might make it fishtail. On the other hand, too much load at the front might cause your car to sag. It can end up in reduced braking capacity and handling power. The good news you, the Curt 25227 is an excellent A-frame coupler ready to take your towing game to the next level! 

For example, this coupler is much stronger than a straight-tongue coupler. No wonder why the experienced of the lot prefer an A-frame coupler for towing their RV trailer to places.

It has a solid neck and a sleeve-locked latch for securely attaching the trailer to your ride. This firmly built coupler makes any trailer go long distances without compromising the truck’s brake system and maneuverability. A tongue capacity of 1875 pounds is pretty impressive, and we think it’s enough to keep accidental trailer sways at bay.

It also supports a gross trailer weight of 12500 pounds. Although it’s half the capacity of a regular gooseneck or a fifth wheel hitch, the 25227 coupler is the best a frame trailer coupler for towing mid-range hiker trailers.

Moreover, its protective carbide powder coating goes the extra mile to prevent any possible damage from the elements. And the steel construction at the core does a terrific job at delivering the CURT promise. The latch can be locked so that you can have peace of mind.

Buying Guide For Trailer Coupler

Before hopping in the market for a suitable trailer coupler, you might first need to know the prerequisites of a decent coupler. Worry not, we’ll provide you with that guide as well!


Let’s be honest with this- trailer couplers aren’t something you would want to buy on a regular basis. You would expect to buy one of these and use it up until eternity, no? This is why you need a durable, long-lasting coupler. One that doesn’t wear off easily, one that doesn’t get loose over time.


This is one of the key issues with people who order trailer couplers online. It is crucial that the couple fits with the trailer tongue, and if it doesn't, then it is of no use. So you need to be extra careful with the measurements. The best way to do it is to buy the product on the spot; that way, you can directly check the fitting and everything.

Even if you cannot do, make sure the specifications of your trailer and the coupler you’re ordering match properly. That should do for you.


Couplers are supposed to withstand heavy force and show a good lot of endurance, so the build has to be sturdy enough. The metal that is used in such a coupler needs to be thick. Look for a Zinc finish to ensure longevity. Some of the quality products come with die-cut steel and certified corrosion resistance- be sure to check if your one has it or not!


If the installation provides you a lot of concern, then why go for that product? Towing something with your trailer is no easy job, and one small mistake in setting the coupler could result in massive disasters.

Go for one that has an easy usage and installation process. The lock-latching system needs to be simple. The coupler lock should be strong but easily accessible by you. Last but not least- if the coupler latches itself, you’re in for a bargain buy!

FAQs About Trailer Coupler

1. How can I attach the coupler to a trailer frame?

Ans: There are two ways that you can attach your coupler to a trailer frame. Bolting it into the trailer frame is an option, while the other is to weld the coupler. Generally, such couplers fit well on the end side of the trailer, but there are differences. You need to make sure that since there are a lot of trailer shapes and sizes- your coupler fits into the right shape.

2. Is bolting a weld-on coupler an option?

Ans: No. You can’t. Never. Weld-on couplers are ready-made ones that do not require any sort of bolting or anything. They are easy setup tools, and all you have to do is set them up properly. That's all. Bolting over a weld-on coupler might seriously damage the tool.

3. Can I weld a bolt-on coupler?

Ans: Yes, you can. Instead of bolting the bolt-on coupler as normal people do, you sure can weld it. But keep one thing in mind- they won’t add to the durability or weight capacity. Moreover, it might stain the tool, so even if you choose to do it, make sure you paint it again once you’re done.

4. What exactly is a hitch-ball?

A trailer coupler helps a trailer to connect or two other vehicles. So there need to be two sides that hold on to the two vehicles. One can be the coupler- the other can be a hitch-ball. It's a simple tool that can enhance the latching abilities of a coupler. Be it a trigger or a handle; it will connect with the coupler and initially tie the two vehicles together. 


As it appears, choosing the right coupler from a number of good options isn’t an easy job. So it all comes down to you and your preference. All of these products from our list do a fantastic job; your job now is to select one that suits your work the most. 

We hope our list helped you choose the best trailer coupler. Best of luck!
