No more struggling in the rain or cold; just squeeze both levers to easily open the ball socket. It's built with robust, solid steel construction to provide durability and reliability for your towing needs.

Sturdy Construction for Peace of Mind: Heavy-Duty Steel Build

When you're towing heavy loads, the last thing you need to worry about is your coupler failing. Built with solid steel, this coupler can reliably handle up to 15,000 lbs GTW, ensuring a safe and sturdy connection to your trailer. The black powder coat finish resists corrosion, making it a robust choice for all weather conditions.

Weld-On Simplicity: Ready for Your Custom Setup

If you're looking for a permanent, secure connection, this A-Frame Trailer Coupler offers a weld-on solution. It's ideal for sudden replacements or customizing trailers. Many users have reported the solid build and perfect fit, contributing to peace of mind and reliable performance on the road.

Perfect Fit for Your Trailer: Standard Coupler Design

Designed with universally recognized specs, this coupler fits a 2-5/16" hitch ball and has a built-in jack attachment point with a standard 2-1/4" diameter jack hole. It ensures a seamless fit and provides a reliable connection point, meeting SAE J684 standards. The fitment is so accurate, users often mention the precision as a standout feature.

Tailgate Convenience: Extended Length Design

With its thoughtfully designed extended length, accessing your truck's tailgate even when hitched is hassle-free. Road trips or loading and unloading become less cumbersome, enhancing your towing setup with everyday convenience. It's these small design details that make life just a little bit easier for trailer owners.

High Capacity Meets Flexibility: 2,250 lbs Tongue Weight

For those who need to haul heavy loads, the coupler can handle up to 2,250 lbs of tongue weight. This characteristic ensures that even with significant weight loads, your coupler can provide the stability and reliability needed for a smooth towing experience.

Fits Your Angle: Standard 50-Degree A-Frame Trailer Angle

Whether restoring a classic vintage trailer or setting up a new one, the coupler fits the standard 50-degree A-frame angle. This assures you that it will conveniently slot into most A-frame trailers without additional hassle, simplifying your setup process.

Super nice quality! great hitch! Love the locking device!

I received my order today, I am very pleased with how quickly it shipped. When I opened the box I was also very pleased with the care taken to use packing papers to protect the contents. I bought a trailer coupler, and I couldn't be happier with the quality of the craftsmanship used and materials used to make it "HEAVY DUTY " . I would highly recommend this product. CA-5280-QB.



by:

It does exactly what I hoped. It moved the trailer back a few inches so I can open my tailgate to access my generator without un-hitching.but keep in mind that if you have a weight distribution set up that means the chain lifts will have to move forward as well. This interfered with my propane tanks so I built a riser for the tanks to secure to. I'm happy with it. Mig welded on real easy.

The swap over looks great, Tim! Being able to open your tailgate I bet is a game changer. Even though you had to make a few mods to get all the other equipment adjusted. I think this was a win in the end.



by:

This is a very nice piece. It works great and is well built. The only drawback is where the tongue jack mounts. My old one was threaded. This one just has holes for the bolts. The front bolt is very difficult to get a nut onto the bolts I had to put the nut in a socket attached to an extension then duct tape a washer to it and put it through the small opening at the bottom to get it started. Other than that it’s a very nice coupler.



by:

These trailer tongues are awesome super easy to use and very durable



by:

Quality product and timely shipping. E-trailer rarely misses a beat.



by:

Heavy duty and was delivered fast and f ree!



by:

Just what we needed



by:

nice product and great delivery



by:

I love the way it couples and the longe distance in front of the jack. Makes it a lot easier to get tailgate down on the truck. Also how I can just go up in the suspension and it locks without me having to get out of the truck.



by:

This product was everything that was shown. The shipping time was right on time as I was told it would be delivered.

Works great



by:

Great product, everything I was looking for



by:

etrailer reached out to me with a a alternate product which was readily available and expedited its shipment to me. I received the product many days quicker than the original product I ordered. Thanks Robert S of trailer.



by:

I had absolutely no problem with it. The welder had no issues getting it welded to my trailer frame. Thank you.



by:

Exactly what I was looking for. Weld on replacement trailer tongue.

  • Looking For Coupler Repair Kit For Atwood 88007 Coupler
    Hello Mark, thanks for reaching out. That Atwood 88007 coupler has been discontinued for a while now, so there are no replacement parts or repair kits available. The best option will be a whole new coupler, such as the A-Frame Trailer Coupler w/ Round Jack Hole # CA-5280-RB which is rated for 15,000 lbs. What kind of trailer is this going on?

  • Replacement 15,000LB Coupler For a 18' A-Frame Trailer
    I recommend installing the A-Frame Trailer Coupler # CA-5280-RB on your trailer. This has a cutout with bolt holes for a tongue jack. It places the opening where it is structurally stronger so it is less likely to bend like your current coupler.

  • Dimensions of the A-Frame Trailer Coupler # CA-5280-RB
    I went out to the warehouse and measured the A-Frame Trailer Coupler # CA-5280-RB and found that from the widest point to the smallest point it measured 10-9/16" and 2-5/8" respectively. This will give you the angle. The overall height of the piece that fits over the frame was about 3-7/8" while the inner height (where it site on the frame) measured about 3-1/4". I have attached a picture and a review video for you to check out.

  • Can I Rebuild my RAM A-Frame Trailer Coupler CA-5400-B
    The A-Frame Trailer Coupler part # CA-5400-B is a full replacement and the only way I know to repair it when it is broken. The Repair Kit for etrailer and Ram A-Frame Couplers part # CA-5100-RK is designed for original trigger latch couplers different than yours. The A-Frame Trailer Coupler w/ Round Jack Hole part # CA-5280-RB is a nice upgrade that can be made which is a 15K coupler that is easier to use and service. Repairs can be made if you're confident it will work and hold but by...

  • Replacement A-Frame Trailer Coupler For 1978 Airstream With 50 Degree A-Frame
    It would appear that that your 1978 Airstream had the standard 50 degree a-frame style coupler. You can verify this to ensure that the etrailer A-Frame Trailer Coupler # CA-5280-RB will fit correctly on your Airstream. I personally prefer the auto latching style couplers like the Demco 50-Degree A-Frame Trailer Coupler # 12660-97SP. This coupler for me is cleaner and works simpler with the latching system. The connection for the jack has nuts welded on to the bottom of the plate making...

  • Can etrailer.com A-Frame Trailer Coupler Be Adjusted
    The etrailer.com A-Frame Trailer Coupler # CA-5280-RB that you referenced does have a nice and convenient squeeze latch that allows for quick and safe coupling, but there aren't any adjustment points on the underside to tighten up a connection. Those bolts that you mentioned are just to hold the jaw in place. We do not have a standard A-frame coupler that has the ability to adjust like this.

  • A-Frame Coupler Recommendation for 14k Trailer
    Ram couplers are solid couplers that as long as you stay under the capacity of them they will work great. I would not recommend a 12.5k coupler on a 14k trailer though. Instead you'd want to go with a coupler with a 15k capacity like the part # CA-5280-RB instead. I attached a review video for this coupler for you to check out as well.
