Video Transcript for Fulton Channel Tongue Coupler with Hand Wheel Latch Repair Kit Review

Today, we'll be having a look at the Fulton Repair Kit for Fulton Channel Tongue Couplers with Hand Wheel Latch for 2" to 2-1/8" balls. Part number F520801. Here's what our repair kit comes with. We have our new hand wheel latch, our new roll pin to secure our latch to our threaded rod here. That way you can't take a latch all the way off. Your spring, your ball catch, and then your ratcheting mechanism to make sure that your hand wheel doesn't back off. The reason you want one of these kits is in case your coupler we're to become damaged.

This will save you time and money, so you can just repair the necessary parts. Over time, these threaded prices here can become damaged. Your hand crank could become difficult to move. Most times, those couplers are welded on, so you have to spend more time and effort. If you don't have a welder, it makes it a very difficult repair process.

This repair kit will work with Fulton 308 series Channel Tongue Hand Wheel Couplers with a 2" to 2-1/8" ball. We have a coupler here off of our trailer. We'll show you how to install replacement parts. Normally, we would have to remove our roll pin right here. We've already removed ours. We will skip that, and we'll show you how the rest of it goes.

We'll press up on our ball latch on the bottom, push down on the ratchet mechanism, spin off our hand wheel. We'll drop out everything from the bottom. We'll set that aside. We'll take our new ball latch, drop in our threaded rod, attach our spring. Once we have that set up, I always like to do this part here first.

It makes it easier. Take our ratchet mechanism, drop it on in. You can hold it in place, while we raise up our assembly. Take our hand wheel, thread it on. You can hear our ratchet mechanism work as we turn it. That's what tightens our coupler down onto our trailer ball. Tighten this down all the way, so it easily install a roll pin. You see our roll pin hole sticking out now. Take our pin, get it in position, and we'll tap it in with a hammer. We have it all the way through now. This roll pin, as you see, when you uncouple our trailer from our tow vehicle, that roll pin stops our hand crank, so you can't take it off all the way and lose your pieces. That completes our look at the Fulton Repair Kit for Fulton Channel Tongue Couplers with Hand Wheel Latches for 2" to 2-1/8" balls. Part number F520801. .

Little pricey, but was exactly what I n eeded.

Its working as well as it did after I installed it. I am still happy with my decision on purchasing it. The new owner of the trailer is quite pleased with it too.
Brian S - 11/13/2022


I had to modify the product because the hitch is not a fulton brand but same style. well....try and find this style coupler for a discontinued or bankrupt company. damn near impossible. after my mod, it works perfectly and saved me hundreds of dollars!!


Unable to use as it did not fit together. The bolt threads were not appropriate. They should provide a bolt with full length treads.

This latch repair kit is designed to be used with Fulton 308 series couplers. I recommend watching our review video below.
-- Etrailer Expert Jenny N - 10/31/2022


My questions received a quick response with the solution to my problem. The repair kit for my coupler arrived sooner than expected and was a perfect fit: my 60+ year old trailer hitch is fully operational again! Thanks for the great service.

I havent had to use it, as it is on a hitch on a Jeep that is only used in emergencies. It worked when I bought it, so I see no reason why it shouldnt operate just fine. It still looks good!
Dave C - 11/30/2017


Got this for a older trailer that has a Fulton ball hitch which the original's locking tab finally broke and the spring went missing. One feature I like about these types is the means of removing the "guts" of the hitch I did not use the rolled pin that came with it instead I use a clip style cotter key that I can remove and remove the "guts" to prevent theft.

Good works and fits well

Happy I found your company .I own an older 1974 U-HAUL Camper and the Coupler had just gotten weak over the years and broke .I spent hours on the phone with U-HAUL and they could not help me with a replacement .The quality of your product looks great , even stronger than the original. Thanks for getting me on the road ,I'll be a happy camper again .


Great service and excellent product. I ordered the wrong part and was able to send it back and get what I needed PDQ!!


These Fulton Coupler parts are hard to find. Good price, very reasonable shipping rates, fast service, worked great.


Bought a trailer, the coupler was missing parts. this kit should fix it!


Perfect replacement kit! Very pleased with purchase


worked perfectly


Shipping was great to Ga. The Kit That I needed was 61-0801. The only 1 listed was 52-0801. But I able to used parts out that kit to make the repair. Had to reuse the bottom ball coupler. The spring was hard to install on this type to get in. I compressed the spring with small cable ties to installed, then cut ties after installation.Works Great!! Thanks Again
PS. only reason I didnt give it 5 Stars. My tongue was Fulton 34-318


We ordered hard to get parts. They arrived 4 days earlier than expected! In December! Wow! Parts are already on the trailer and working beautifully. Couldn’t ask for better service!


First, I thought that these where no longer made since the trailer is from the early 40's and is home made. Even the axle is unique (cannot find information on it or about it) I am restoring this trailer to be my light utility trailer for beach and picnic gear and minor trips so I wanted to make sure the hitch devices are good and it fit greatly minor differences to the old one though may order another as a spare since I remove these parts from the hitch and put a lock (double anti theft protection) when leaving the trailer somewhere.


Had to wait for a good while on product because of manufacturer backorder. But as soon as it was in stock I received a call and they sent me a link to make it easy to order. Once ordered I had it within a week very satisfied with


Everytime I need something trailer related, motorcycle, RV, boat, etc, they've got what I need and get it to me quick. Thanks


I inherited an old 1969 boat and trailer. I planned to tow it to a shop for repairs when I discovered that a few of the parts on the old coupler were either rusted or missing. I was thrilled when I saw that I could replace the required parts at I located a coupler on the website which matched the coupler on the trailer. A few days, later I received the kit in the mail, and it even came with a picture of how to assemble the unit. It fit on the old trailer and worked great! Thanks for stocking the old stuff that we all need from time to time.


It took time for my order because of the manufacturer and etrailer kept me informed as the process went along. Thanks for your great customer service.

On year, working great. Thanks.

I purchased this to replace a broken one on a teardrop camper trailer. It arrived on time and after about 30 seconds had it installed on the hitch without any issues. Easy ordering process and prompt delivery with no issues at all.


I have an OLD trailer and the hitch assembly broke and needed to be replaced. is the ONLY place that I could find that carries this repair kit.
Needles to say this Saved me a ton money and time.
I Ordered the kit late wednesday evening and it was here Monday
The diagrams on the the instructions were very EZ to read and follow.


Exact fit replacement. Works perfectly.


I had misplaced the coupler for my old trailer and didn't really believe I would find a replacement. But was pleased when I found "etrailer" and they had exactly what I wanted.

This little gadget was even better than the old one.....nothing cheap or chintzy about it. Worked great!

Also, very pleased with the customer service provided when I ordered and exceptionally pleased with the speed of delivery of this item.

I heartily recommend this website and this business. Thank you!


The product is an exact replica for a hopelessly rusted part on a 64-year-old box trailer I built long ago. I was ecstatic to find it since otherwise I would have had to re-design the entire front end. The trailer is still being rebuilt but this product is scheduled for action soon. Thank you for having this in your stock. Richard A. Moore, Solana Beach, CA


This part was not easy to find. Thank you eTrailer for having it in stock! Easy to install works as expected.

As expected, no concerns.
Muss M - 08/21/2016


The product is fine. I am not unhappy about the order, shipping or the speed at which I received the item. I apparently am looking for a universal replacement handwheel latch for a 2" ball as this one will not fit my trailer tongue because it is not a Fulton tongue....
Back to the drawing board.

  • Repair Kit Recommendation for Channel Tongue Trailer Coupler
    The Repair Kit for Fulton Channel Tongue Coupler with Hand Wheel Latch, # F520801, fits the Fulton 308 series couplers. The Repair Kit for Husky Channel Tongue Trailer Couplers, HT87084 (discontinued), fits the Husky 6,000 pound straight-tongue coupler for 2 inch hitch balls. Since both of these parts were designed to fit different brands of couplers, I can not guaranty that these will interchange. In order to determine which repair kit will work for you, I would just need to know the...

  • What Size Bolt Does Handle Thread Onto for Repair Kit for Fulton Channel Tongue Couplers
    I went out to the warehouse and pulled Repair Kit for Fulton Channel Tongue Coupler # F520801 to measure the bolt used to thread the knob on. it is a 5/8 inch coarse threaded bolt. If this will not work, let me know the brand coupler you have, the capacity, and the ball size it is for and I can determine if we have something that will work.

  • Repair Kit for Fulton Channel Tongue Coupler with Hand Wheel Latch, # F520801, Accepts 2 Inch Ball
    I spoke with my contact at Fulton. He stated the Repair Kit for Fulton Channel Tongue Coupler with Hand Wheel Latch, # F520801, is for the 34318 series Fulton handwheel couplers that accept a 2 inch diameter ball.

  • Fulton Coupler Repair Kit is Too Large for Coupler on Homemade Trailer
    First, check the coupler you have for any model numbers or manufacturer information, and capacity. that will go a long way in determining if there is a kit that fits the coupler you have. Without knowing a make or model on the coupler I cannot guarantee that any of the repair kits we have will work. Also, it is unlikely that you would be able to switch latch styles given the fundamental differences between the two. Is the coupler welded on the trailer? If it is not welded on and we can't...

  • Repair Kit Recommendation for Sailboat Trailer with Hand Wheel Style Coupler
    From the picture you submitted I certainly looks like the latch on the part # F520801 would be the right part. Just looking at the picture you have submitted it would appear as if you have a Fulton coupler that this kit would be designed to fit. The latch for the ball is identical so this would work well for you.

  • Fulton Hand Wheel Coupler Repair Kit
    The Repair Kit for Fulton Channel Tongue Coupler with Hand Wheel Latch, 2" to 2-1/8" Ball # F520801 is the only kit available for that hand wheel repair. You will need to get the entire kit as the spring and latch are not available separately.

  • How Thick are the Walls on the Fulton Coupler with Hand Wheel Latch Part # F3080217
    I went out to our warehouse and measured the Fulton Coupler with Hand Wheel Latch part # F3080217 for you. The side walls are 3/16" thick. What I really like about this coupler is there there is a repair kit for the latch, part # F520801 which is a very nice feature for a weld-on coupler like this.

  • Why Would Trailer Coupler Latch Cut into Hitch Ball
    Sounds like the latch of your Fulton Fast-Lok Coupler # F346000301 is either adjusted too tight and/or is damaged. The nut you see on the bottom of the latch, try loosing it slightly to see if it end up putting less stress on the ball. You will want to test fit a 2 inch hitch ball in this coupler to make sure it is tight enough to be secure but not too tight.

  • Is the Repair Kit # F520801 Rated for the 5,000 lb Fulton Coupler with Hand Wheel Latch # F3080217
    The Repair Kit # F520801 is the correct kit for the Fulton Coupler with Hand Wheel Latch # F3080217 rated for 5,000 lbs like what you referenced. The repair kit itself wouldn't have a weight rating as it is designed to be used for the Fulton 308 series couplers. I tried looking up the other answer you mentioned but I wasn't able to find anything stating that the kit was only rated for a 2,000 lb coupler.

    I wish we had replacement parts that would work for your trailer, but the best solution we have would be to replace the coupler since we do not carry the repair kit you need. For a similar hand wheel style coupler we have the part # T2343400.

    It sounds like you need a repair kit for a trailer jack that uses bevel gears. We do have repair kits such as # F0933306S00 that works with a whole range of Fulton marine and recreational jacks. This and similar kits can be seen on the linked page.

  • Latch Repair Kit for a Fulton Trailer Coupler
    The Coupler Repair Kit part # C25194 is designed for Curt trailer couplers that use a 2" hitch ball. Since you have a Fulton trailer coupler I cannot recommend you use this kit. Instead, I recommend taking a look at part # F670801 which is for 44125W and 44150W series couplers or part # F520801 which is for 308 series couplers. If you do not have either of these then the only option I have for you would be to replace the coupler as the repair kits are not universal. I have attached a list...

  • Latch Repair Kit for a 1-7/8 Inch Trailer Coupler
    If you have a Fulton latch style coupler, I spoke with my contact at Fulton and they no longer supply the repair kits for 1-7/8 inch straight channel couplers. They told me that what most customers have been doing is purchasing the coupler the same coupler and removing the parts they need to do the repair. For a latch style coupler we have # E112000340. And for handwheel couplers we have # T2343400 and # T2343400183.

  • Replacement Coupler vs. Coupler Repair Kit
    Since you want to sell the trailer, and since the current coupler is a bolt-on type, I suggest you replace the coupler with a new one. You add an appealing "selling feature" to your trailer (the brand new coupler) and one like 2-inch # CT-3001-Z (for 2-inch wide channel) or # CT-3003-Z (for 3-inch wide channel) will cost you LESS than the repair kit.

    In order to find the right coupler or latch for your trailer you will need to know the size of your trailer tongue or the model of the coupler needing the parts.
