Video Transcript for Fulton Straight Tongue Trailer Coupler - Standard Coupler - F222000301 Review

Today, we're going to do a review on part number F222000301, the Fulton Fas-Lok Trailer Coupler design to fit a 2" hitch ball, fits on a 2" channel. This coupler is a trigger latch style. It has a Z-Max 600 finish. It offers superior corrosion resistance. It does fit a hitch ball size of 2". The channel, we'll measure that it fits on is 2" wide.

And other measurement we will need is the diameter. The distance between the side mounting holes, we'll measure center-to-center would be 3". This coupler has a weight capacity of 3,500 pounds. And that should do it for a review of part number F222000301.

The popular and efficient, trigger-style latch on this corrosion-resistant, straight-tongue coupler helps to make hookup quick, easy and secure.


Very happy with this purchase and others. I bought several products from etrailer when rebuilding a trailer I got from my Son in Law. I found the various videos describing the products I purchased were extremely informative and removed doubt about whether I was getting the correct Item. I now have a rebuilt trailer that is reliable and just what I needed to haul my four wheeler. Thanks for your help!


Here are some photos of my installation with the Fulton Fas-Lok Coupler, 2" Ball, 2" Channel - 3,500 lbs and the Tow Ready Interchangeable Hitch Ball Set with 1-7/8" and 2" Hitch Balls:


Just what I wanted. Just what I received.
Thanks etrailer.


I replaced the smaller hitch coupler on my log splitter with this 2" one so that all our trailers are consistent and I don't have to swith balls. New hitch coupler works fine. I'm using it in a very lightweight application so not much of a challenge for it but I'm happy with it and would purchase again.


I bought a axle, springs wheels, hubs etc. to build a utility trailer, I inadvertently had ordered incompatible hubs for the selected axle the person filling the order noticed this and contacted customer service to alert them of the issue who then called me to correct the problem. This saved me the time and expense of returning the part and delaying the project. great service, attentive, knowledgeable employees and great products.
Thanks E trailer.

Kirby L - 11/13/2017


Product was delivered as advertised and on time. I was trying to modify an older trailer with a tongue that was too long. I was able to shorten the tongue and easily mount this hitch.


Standard bolt holes, does what it needs to.


I upgraded my 8" trailer tires to 12". The boat rides alot smoother on the trailer. The tires came on-time and were as described. I tow this trailer to various sailing regattas in our area, usually within 25 miles. The coupler is well built, although I did not get to install it yet. I replaced the T-One vehicle wiring harness, as the Honda harness failed after 9 years.


Great product. Installed nice and easy on my older, "home brew" kayak trailer. Hardest part was drilling the four 1/2" holes in the tough. I clamped the coupler to the toungh, and used the coupler's holes as guides.

3"x1/2" Grade 8 bolts were used to have enough length for split ring lock washers.

Latch mechanism is nice and smooth.


I ordered multiple items from etrailer and the experience was perfect. The products arrived exactly as described with super fast shipping (standard option). The communication was frequent and thorough. This company knows good customer service. I didn't have any issues, but don't have any worries with this company if any come up.


etrailer was very helpful in providing other dimensions since I needed a replacement for an old Fulton and did not want to drill new holes and weaken the tongue. They found one that had the proper bolt spacing and locations for my existing holes. Still had to cut ~ 1/8" off the end of the tongue for all to fit. Nice coupler, great service!


product is made well and think should last. The only problem would like to see the bolts inculed to connect coupler to frame of trailer. My old one spring broke in release latch and this one came just in time before having to use trailer moving household. Thanks again!!!!!!!!!!( will use etrailer again)


Ordered the 2" Ball, 2"Channel Fulton Fast Lok to replace the old
1 7/8 on my utility trailer. Hard to find 2x2, not as common, but had in stock and delivered fast. Thanks guys.


Easy installation, works like it's supposed to. Replaced a coupler which was a couple yearts old and never worked properly.
Arrived quicker than promised.
All good.

I have towed Vintage race boat several times from Florida to Canada and places in between trouble free.

2 inch coupler is of good quality, will weld it on tommorrow.

Its been a year now and coupler shows no sign of wear and tear and I use it almost daily.
Glen W - 06/10/2016


I just wanted to say how pleased I am about my latest order! I ordered 4 items Tues. evening & received them 2 days later! I have ordered from you several times & have been pleased every time! Thank you so much!!!


Work perfect for my boat trailer excellent product

Still working great
Ralph - 12/07/2018


great service & fast shipping . i am a repeat customer, and will be again!!! hard to find a 2" channel with a 2 " ball . they had it in stock & was shipped the same day i ordered it . great quality .


No, all stamped steel ball couplers aren't the same! I've used cheaper ones, and they are a crapshoot. They have poor tolerances and therefore can be stiff and hard to handle. The Fas-Lok works every time, all the time, and it looks as good after a year or two as the day I first installed it.


Solidly built & smooth lever operation. Perfect fit on my ancient 2"x3" box section boat trailer.


Wish i had replaced this earlier on our small utility trailer. It is so much easier to use.


Simple, strong bolt-on solution for the small camping trailer I'm building.


First of all the packaging was stellar. May not sound like much but says alot about the culture of the company. Have not installed the product yet so can’t attest to the functionality however the quality is top knotch. Will definitely make future purchases.


Good coupler for the price but shipping was very poor and box broke open on deliver as packed very bad in a poor weak box


Fit perfectly! Shipping took two days cant beat etrailer

  • Replacement 2 inch Fulton Coupler for Trailer With Damaged Latch
    I really wish we had a coupler repair kit that would fit what you sent in a picture of. But the best option we have would be to replace the coupler. It looks like you had a coupler similar to the # F222000301. This is a 3,500 lb rated coupler that is designed for a 2 inch hitch ball like what you currently have.

  • Is there a Difference Between Fulton Couplers # 222000101 and # 222000301
    There actually is no difference between the two part numbers you referenced. Both of them are the Fulton Coupler # F222000301. The difference in part number is in how they are packaged when we receive them. I attached a review video for this coupler for you to check out as well.

    A repair kit is not available for your Fulton Fas-Lock Coupler but I do have a solution for you. If your coupler is welded on the trailer tongue you can purchase a coupler like part # F222000301 and remove the parts you need to repair the coupler you have on your trailer.

  • Availability of Trailer Coupler With Mounting Hole Spacing of 2-1/8 Inches For 1983 Viscount Caravan
    Anytime you modify a part, it can compromise the safety and integrity of that product. I can not recommend to modify the Fulton Trailer Coupler, part # F222000301. I do not have any bolt-on couplers with a mounting hole spacing of 2-1/8 inches. The mounting holes are all at the industry standard of 3 inches.

  • Bolts to Install Fulton Fas-Lok Coupler Part # F222000301
    To bolt the Fulton Fas-Lok Coupler in place, I would recommend using two 1/2 inch by 2-1/2 or 2-3/4 inch grade 8 bolts. We do not offer the bolts, but they should be readily available at your local hardware store.

  • Replacement Coupler for a Store Brand Utility Trailer
    If your utility trailer has a 2 inch wide by 3 inch tall square tube pole tongue and the capacity of the trailer is 3,500 lbs or less, the Fulton Fas-Lok Coupler, # F222000301, will work great for you. You can measure the distance between the mounting bolts on your original coupler to see if new holes will need to be drilled for installation of this coupler. If your coupler mounting holes are right at 3 inches then this coupler will bolt on just fine, see video. I added a link to all...

  • Recommended Coupler For Magic Trailer With 2 Inch Wide Channel
    We have a few standard couplers that are designed to fit a trailer tongue that is 2 inches wide. I have attached a link to our product page for the couplers we offer you can check out. You would need to select the coupler that matches the hitch ball size and weight capacity you need for your trailer. If you need a coupler that has a 3,500 lb capacity and fits a 2 inch hitch ball I recommend the Fulton Fas-Lok Coupler, part # F222000301. This coupler can be bolted or welded on and features...

  • Coupler Solution Recommendation for 2 inch Channel Trailer for 2 inch Ball
    You could have the Fulton Coupler part # F222000301 welded to your trailer frame since the bolt holes don't match up perfectly. This would be the most ideal solution actually.

  • Where Can VIN Number Be Found on Boat Trailer?
    VIN numbers are sometimes difficult to find on trailers as there is not a specific required position but they are usually imprinted somewhere in the metal. They can be posted anywhere along the frame rails, but most often are found near the coupler. If no VIN number can be found, you can contact the State Highway Patrol to have them issue you one for your trailer so you can properly register it.

  • Recommended Mounting Hardware for Fulton F222000301 Fas-Lok Trailer Coupler
    I'd be happy to assist with that. You'll need two 1/2 inch by 2-1/2 inch long grade 8 bolts with the appropriate nuts and washers. You should be able to find those at your favorite hardware store. If you click the provided link, you can see a product description video featuring the coupler you'd looked at.

  • Is Mounting Hole Spacing the Same Between 1-7/8 and 2 Couplers for 2 Inch Tongues
    All of the 2 inch ball couplers that fit a 2 inch channel such as # F222000301 have a hole spacing of approximately 3 inches on center (front to back). The 1-7/8 inch coupler # DL23870 has a hole spacing of 2-1/2 inches. If you go to a 2 inch ball coupler you will have to drill at least 1 new hole through the tongue.

  • Is Fulton Coupler Needed to Use Thule T2 Bike Rack on Volvo XC90
    The link you sent didn't work, but as long as the hitch ball you have is 2 inches in diameter the part # F222000301 would attach to it. You should note that this installs on a trailer tongue that is 2 inches wide. It would not be used in conjunction with a bike rack at all. If you wanted to use a Thule T2 part # TH83JV you would need to have a trailer hitch installed on your vehicle that has an opening that measures 2 inches by 2 inches. The coupler you mentioned would not be able to be...

  • Dimensions of Channel Tongue Trailer Couplers for 2 Inch Frame
    Between the bolt holes of coupler # CT-3001-Z I measured the same 3-1/16 inch. They're also 1/2 inch holes like yours. From the top to the center of the holes I measured about 1-5/16 to maybe even 1-3/8 inches. With that being said measuring from inside the coupler's channel from the top to the center of the bolt hole makes more sense. If the metal of the new one is thicker than the old one it'll still fit exactly the same even with the outside measurement being different. So I measured...

  • Trailer Coupler Recommendation for a Round 2 Inch Diameter Straight Tongue
    You will want to use a coupler made to fit on a round tube rather than a square one. We have several options such as # BD028242 or # BD028383. However, these couplers do not have an exact 2 inch measurement so you may need to have some fabrication done and weld the couplers on. This work should be done by a qualified professional welder. Coupler # BD028242 has an outer diameter of 2-1/4 inches and a 1-3/4 inch inner diameter. Coupler # BD028383, which would fit around a pipe, has a 3-1/2...

  • How to Determine Correct Hitch Ball Size for a Fulton Coupler
    The Fulton Fas-Lok Coupler # F222000301 does have the same 22 200 SAE Class 2 numbers that you referenced but that has to do with the testing as opposed to the hitch ball size. If you check out the picture that I attached you can see that the handle itself has 2" Ball engrave on it. Your coupler should have this on the handle or on top of the coupler part that sits directly on top of the hitch ball. If you still can't find it then you should be able to go to your local home improvement...

  • Replacement Straight Tongue Coupler for 2" Hitch Ball
    If you are looking for a straight tongue trailer coupler with a 2" coupler you can use the Trailer Coupler # DL13847 if you have a 2-1/2" tongue or the Fulton Fas-Lok Coupler # F222000301 if you have a 2" tongue. If the tongue of your trailer is a different size and you let me know what you have then I can make an alternate recommendation for your tongue size. If you are looking for an entire replacement tongue we do not have them except for a specific replacement like for the Yakima Rack...

  • Looking for Trailer Coupler for 3 Inch Channel Tongue With 2-1/2 Inch Mounting Hole Spacing
    The typical center to center hole distance is around 3 inches, much like the hole spacing of the # F222000301 Fulton coupler you'd looked at. If you're speaking of the distance between the inner edges of the holes, and not the center to center spacing, the holes have a gap of about 2-1/2 inches between them. If you don't mind going with a 2 inch ball, this might be a good choice for you. If you'd prefer to stay with a 1-7/8 inch ball, you could use the etrailer brand # CT-2003-Z, but...

  • Will Mounting Holes for 1-7/8 Inch Hitch Ball Coupler Match With 2 Inch Hitch Ball Coupler
    Your standard coupler for a 1-7/8" hitch ball, like the Fulton # E112000340, has bolt holes measuring 2-1/4" apart on center while your standard coupler for a 2" hitch ball, like the Fulton # F222000301, has bolt holes measuring 3" apart on center for your standard coupler. There isn't any issue with using a 2" coupler for your application (you just have to drill new holes) so I say go ahead and upgrade it to the more standard hitch ball size. We do have some couplers that have some adjustability...
