Video Transcript for Fulton A-Frame Trailer Coupler - Standard Coupler - FE443050303 Review

Today we're going to be taking a look at part number FE443050303. This is the Fulton A frame coupler. The A frame coupler is sturdy and very simple to use. It's going to provide your attachment point for your two and five sixteenth inch hitch ball. It's going to be made from a steel construction. It's going to have a black primed finish on it and this is a weld on design.

Right here, you're going to have your low profile latch. It's very easy to use, offers a nice, sleek appearance. In order to open up the mechanism here in the socket to receive your hitch ball, flip the latch up and then pull it back. Then, it's going to remain open, that way you can make your connection. See how that opens up the mechanism right there Then, to close it, simply lift it up and push it forward and it's going to drop back down and then that closes the mechanism around the hitch ball. It's going to have a small pin hole located in the latch, that way you can install a coupler lock system or a coupler pin.

That is going to be sold separately. The diameter of that hole's going to measure about five sixteenths of an inch and then when choosing a coupler pin or a coupler lock, you need to make sure that it has a span or usable pin length of about seven eighths of an inch. That's about the width of that latch right there. We're also going to have the built in jack attachment area. This is going to provide a convenient location for mounting your A frame utility jack. The large hole is going to give us a diameter, looks to be about two and five sixteenths of an inch, so that's going to be perfect for jacks that have a diameter on the outer tube of two and one quarter of an inch.

These mount holes are going to be separated on center. This one's about three and three sixteenths of an inch. This one right here is going to be about two and fifteen sixteenths of an inch. It's going to be the same for that measurement there. Now, a lot of those holes on your standard A frame jacks are going to have elongated holes, so this hole separation is designed to fit your standard three inch mount pattern for A frame jacks. Again, this unit's going to feature a nice steel construction.

You also got the lip that goes around the socket right here so potentially some of those socket locks that are out there on the market to help protect your unattended trailer, some of those would fit on this unit. You just have to check out those and see if they would fit on this particular coupler. Again, it is a weld on design. This is designed to fit the industry standard fifty degree A frame trailer frames. Your ball size on this unit's going to be two and five sixteenths of an inch and the capacity of this coupler is going to be ten thousand pounds. If we take a look at the overall length, measuring from the very front to the very back, we can see there that it's going to give us a measurement that looks to be about twelve and three quarters of an inch. That's going to do it for our review of part number FE443050303.

Still working like new


Will do the job as long as you don't use a wheel on the tongue jack. Used one and the center of the couple started bending and warping out of shape.

This does not sound like anything I have heard before. Can you please send me a photo and tell me what model jack and wheel you have?


i am pleased with the part that arrived and the handling of the original one being out of stock - id really like if they update their order system however, as it's very annoying to receive an email that suddenly the part is out of stock, and be hit with the fact that the only other ones are more money... bit of a bait and switch, i did however get offered a discount and they were more than helpful in making sure to find me another part that was correct and would meet my needs



It’s, well it did what I needed it to do - which was be part the important part of a custom tow bar I had made to get our broken down RV from Las Vegas to Modesto behind a UHaul truck I had to pair it with you 2in to 2 14? Inch adapter that was supposed to be used with one of your weight safe hitches, it worked fine but I really haven’t needed to use it again In the last year - we don’t move the rv any more so it’s just hanging out on the front of the rv laying kind of on the ground - for what it’s worth though, there is not a hint of rust on it and every so often when I play with the latch for kicks it still works freely I keep the ball adapter stored in there and let’s go and latches back up fine, sorry I can’t say a whole heck of a lot more


Went on great no issues. Welds really n ice


I received it yesterday and it will be installed tomorrow morning. Looks like it should work.



It’s working great had it welded on and it is going strong


I needed to upgrade the hitch coupler on a homemade car hauler and this one worked just fine for my needs.


I appreciate working with and the excellent customer support. Highly recommend!


good quality, fits the ball nicely, the new jack I used fit good, I did reinforce around the jack.


Perfect coupler for my Hi-Lo camper. As for etrailer's delivery, it was very fast and their customer service as nd sales team are awesome!

  • Recommended Coupler Replacement for Custom A-Frame Trailer
    The A-frame couplers are a standard 50 degrees angle from outside of frame rail to outside of frame rail where they come together to meet the coupler. The Fulton coupler # FE443050303 you mentioned will be a good replacement for most trailers as long as they fit within the 10,000 lb weight capacity. This coupler will give you a standard hole for a trailer jack as well as fits the standard 3 inch on center mounting holes of most jacks. Couplers like this are not rated for a rise or...

  • Will Fulton Weld-on A-Frame Trailer Coupler Fit a 2002 Haulmark Grizzly Cub Trailer
    Fulton A-frame coupler # FE443050303 is built to the industry standard 50 degree angle that nearly all A-frames are so it should fit your 2002 Haulmark trailer just fine. The latch is a typical latch that will hold itself open until you close it.

  • Weight Capacity of Fulton 50-Degree A-Frame Coupler # FE443050303
    The capacity of the Fulton 50-Degree A-Frame Coupler # FE443050303 that you referenced is 10,000 lb total trailer weight and 1,000 lb tongue weight. I attached a review video for this coupler for more info for you to check out as well.

  • Weld On Coupler Recommendation for a Car Hauler
    For your A-frame trailer the Fulton A-Frame Coupler part # FE443050303 would be an excellent choice. This has more than enough capacity at 10k total trailer weight and uses 2-5/16 inch hitch ball which is a more popular size ball for higher capacity towing setups like yours. This coupler would need to be welded on. I attached a link to a page that has all of our 2-5/16 inch hitch balls as well. You will need to select the diameter shank you need from the filters. You would need to measure...

  • A-Frame Coupler Replacement for 1988 Argosy Airstream
    Yes the Fulton A-Frame Coupler # FE443050303 that you referenced will work great to replace the coupler you have on your trailer. Trailer manufacturers all made the angles of the front of their trailer the same (50 degrees) which allows replacement couplers to be easily found like this Fulton.

  • Replacement Coupler for Atwood AT88007 with Damaged Pin
    I wish we could help but the coupler and it's repair kit that you need were both discontinued three years ago so we can't get either. Best option would be a new coupler like the Fulton part # FE443050303 which has the same trigger design, same 10k capacity, and also fits the 2-5/16 inch ball design as well.

  • Recommended Replacement Coupler For Wells Cargo Trailer That Has Coupler Missing Parts
    I have a complete replacement option for you, but unfortunately we do not have any confirmed replacement parts for the coupler of your Wells Cargo Trailer. Instead I recommend going ahead and replacing the entire coupler with the Fulton 50-Degree A-Frame Coupler, 2-5/16" Ball, Low-Profile Latch, Primed Finish - 10,000 lbs # FE443050303 which has the same 10,000lb rating as your trailer. This coupler fits standard 50 degree A-frames which your trailer more than likely has, but I recommend...

  • Troubleshooting Fulton A-Frame Coupler That Is Not Latching Correctly On Hitch Ball
    One of the biggest culprits that will not allow the latch to go down as far as it originally did is because there is dirt or debris in the mechanism. Also if it is really dry that can effect the latch. I first recommend checking for any signs of excess dirt or anything that would inhibit the latch. Then use a good lithium grease like part # L11354 and make sure all of the parts are well lubricated and working properly. Put some of the grease on the ball as well and try hooking and unhooking...

  • Replacement Trailer Coupler Recommendation for a 1995 Airstream Excella
    I recommend checking out the eZ-Latch Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole # 12660-97SP which is rated for 21K, fits a 2-5/16" hitch ball, and has the standard 50-degree bracket size. You'll want to double check what you have though to make sure this is a proper replacement. Without knowing the specifics of your current trailer coupler this is just an educated guess in all honesty.

  • Recommended Coupler Lock for Low-Profile Trigger
    For your A-frame coupler similar to the Fulton # FE443050303, I recommend the Trailer Coupler Lock - Deadbolt Style for Surge Brake with 2-1/2" Span # e98887. This lock will allow the ends of the lock to be on either side of the coupler giving you the compatibility with low profile trigger. Another option is the Master Lock Adjustable Trailer Coupler Lock - Stainless Steel # 2847DAT which will allow more of a custom fit.

  • Mounting Bracket for DL22530 A-Frame Trailer Jack
    The jack already has a mounting bracket welded to it, as shown in the provided photo. If your trailer does't have a mounting plate, the easiest way to provide a plate would be to replace your coupler with something like # PSE338050303 for a 2 inch coupler, which has an integrated mounting plate for the trailer jack.

  • Converting a 2004 Tomahawk 10K Car Trailer to Electric Over Hydraulic Brakes
    It sounds like you want to convert the surge brakes on your trailer to be used with an electric over hydraulic actuator. If that is the case then you will need an electric over hydraulic actuator, trailer wiring, breakaway, compatible brake controller, and new trailer coupler. The best electric over hydraulic actuator we offer is the HydraStar Marine Electric Over Hydraulic Actuator. The reason for this is because they tend to last longer and have a quicker response time then their competitors....
