This jack adapter plate quickly bolts onto the Fulton XP10 or XP15 mount that is welded onto your trailer, so you can easily attach a Fulton F2 jack (sold separately). Simply remove your old jack from the XP mount and bolt on this adapter plate in its place with the included hardware.


Remove locknut from XP jack swivel assembly

To install the Fulton jack adapter kit, first you will need to use a 3/4" wrench to remove the locknut from your existing XP jack swivel assembly.

Install the adapter plate onto the jack mount

Install the adapter plate onto the jack mount so that the letters TOP are legible as shown. Then make sure the plate is seated in the welded mount and secure it using the included locknut. Tighten the locknut to 65 - 75 ft-lbs.

Attach your F2 jack to the adapter plate

Attach your F2 jack to the adapter plate with the 3/8" cap screws and lock washers as shown in the diagram above. Tighten these screws to 25 - 35 ft-lbs.

Sharkskin Coating for Corrosion Resistance

This plate is coated with Fulton's Sharkskin finish to resist corrosion, making it ideal for your boat or snowmobile trailer. Sharkskin products undergo a test in which they are sprayed with a 5-percent salt solution to determine corrosion resistance over time. These products are able to withstand 1,200 hours of constant exposure to the saltwater mist. This 1,200-hour salt spray rating indicates that a product is not only durable enough to last in freshwater environments, but it can also be used on trailers that come into contact with saltwater.

This Sharkskin finish is also self-healing. By minimizing the effects of any scratches that may occur, Sharkskin helps keep your adapter plate looking like new.

Install a Fulton F2 jack onto your trailer's existing Fulton XP10 or XP15 jack mount. Simply bolt this adapter plate onto your welded-on mount. Sharkskin finish resists corrosion. 1/2" Pull pin hole.


This adapter, coupled with this tongue jack part # F1413060334 were just what I needed to upgrade/replace my bent trailer jack. jay at was great to work with!


Very heavy duty plate. Since I had to return the jack didn't need the plate.


Does EXACTLY what it is advertised to do. It was delivered very quickly and I couldn't have asked for a better experience.

I upgraded to the Fulton F2 and had an old center lock Fulton jack on my trailer. After failing to install the F2 with the included hardware (I did not order from etrailer) I did a quick Internet search and luckily came across Found this adapter and my problem was solved.



Everything is as it was when I but the product. Works as if it were new.


Just what I needed to attach my new Fulton F2 trailer jack with single bolt center mount. Product is heavy duty - I am sure it will last longer than the jack or trailer!



So glad Fulton doesn’t use cheaper material for this part. Super happy with purchase.


Existing EZ Loader trailer did not have a center hole cut. Drilled hole added washer, lock washer nut then locking nut for center. Lined up perimeter holes w/ jack holes tightened down and has worked like a CHAMP!!



Great product!! Heavy Duty and sturdy! Buy with confidence!


The plate bolted right on to the existing plate that was welded to the trailer. The entire process took less than ten minutes to have a new F2 jack bolted on and ready to go.



it is great never had one problem with it F2 Jack or the plate.


This product worked beautifully for my application. I fit well and allowed me to upgrade the older and flimsier Fulton jack to an F2 jack. My big complaint is that the threads of the plate were not finished well on the face-side, and I was unable to start the studs on two of the 4 holes without risking crossthreading. Since I didn't have a threadcutting tool, I had to run the studs through from the backside and use the studs and socket wrench to force-cut the final thread in the plate. Fortunately I didn't break off a stud. Once I had done this, I was able to start the thread from the front and tighten the new jack into place. Poor quality control on that aspect, but otherwise fit very well and did the job.


Worked as described


The new trailerjack arrived in two days after placing the order and the mounting process could not have been easier. Everything fit perfectly and I could not be happier. Great job etrailer! The help that I received from the sales rep (Adam) was very helpful in insuring that I got the right parts. If needed, I will definitely use this company again.


Excellent product


This adapter plate is just what is needed for the F2 jack install. it even comes with hardware. The adapter is threaded so it doesn't need nuts. It's also half the price of all the other adapters out there. way to go Etrailer for offering a easier, less expensive option.


This adapter plate is a life saver. Totally worth the money vs paying to have the old mount cut off and a new one welded on. I was able to put the jack on and get it all adjusted in 20 minutes.


Adapter and F2 Jack worked as expected. A big improvement from factory trailer jack.


I took off an older, flimsy jack that had the single bolt install, and used this adapter kit for the F2 that I bought. Installed quickly and easily.


We are waiting for the Replacement Hardware Kit to arrive so we can get the new jack mount on the boat trailer.


Perfect fit for my Moomba LSV Boatmate trailer. Excellent customer service. Thanks again


Worked perfectly on my Mastercraft trailer to adapt the Fulton F2.


This adapter plate worked for my conversion. There is more slop in it than I would like to see, but it does the job.


Just what I needed and arrived quickly. This is the only and best way to replace a switch g up boat jack. No welding need just bolts right on.


Great Peoduct and easy install! Highly recommended! Worked perfectly!


Product was delivered on time and better then expected!


Good part, used u bolts that came with jack. Will use it later.


Shery was super helpful and the product bolted right on. So easy...!


Great service and delivery. Product was what I needed.

  • Hardware Required to Install Fulton F2 Marine Jack on Fulton Jack Adapter Kit # F500320
    The adapter plate you referenced, Fulton part # F500320, does include installation hardware. This adapter allows installation of a Fulton F2 Series jack on an XP10 or XP15 jack mount. The 1600-lb-rated F2 jack you referenced, part # F1413020134, is compatible with this adapter and is rated suitably as a replacement for the XP15. My contact at Fulton confirmed that you do not need additional hardware to mount the jack. The 4 bolts that come with the adapter plate attach it to the XP15 mount,...

    I reached out to my contact at Fulton and the Fulton F2 Swing-Up, Wide-Track Trailer Jack, 8" Single Wheel, Sidewind, Bolt-On - 1,600 lbs # F1413040134 is desinged be used with the Fulton Adapter Kit - Weld-On XP Jack Mount to F2 Swing-Up Trailer Jack for 3" x 4" Frames # F500320.

  • Weld-On Plate That Is Compatible With Fulton XLT Trailer Jacks
    I went ahead and checked out your Fulton XLT Bolt-Thru Swivel Trailer Jack # F26ZR, and the Fulton F2 Swing-Up Trailer Jack, and you actually won't be able to use this mounting bracket with your XLT jack due to the fact that the plate for the F2 jack is different, and will get welded to your trailer. The bolt on Fulton F2 jack attaches to your trailer the same way, with the use of a u-bolt. However, what you could do, is use the: -Jack Mounting Bracket for Fulton Marine Jack and weld...

  • Mounting Bracket for Fulton F2 Trailer Jack # F1413040134
    The mounting bracket for Fulton F2 jack # F1413040134 uses u-bolts and fits 3x3 or 3x4 inch frames. It bolts on to the side of your frame. If you do choose to weld-on that bracket, you would use part # F500320 and the welding should be performed by a professional welder. Take a look at the install video for your jack and see if that clears things up for you.

  • Mounting Bracket Bolt Pattern of the Fulton F2 Trailer Jack
    I spoke with my contact at Fulton and he informed me that the mounting flange of this Fulton F2 Swing-Up Trailer Jack # F1413040134 and all of the other F2 jacks has center to center bolt hole measurements of 3.44 inches by 4.44 inches. What that means is that you could install this jack on either trailer frame with either a 3 inch tall frame or a 4 inch tall frame if you were using U-bolts.

  • Recommended Mounting Bracket For Fulton F2 Jack
    If you measure the distance between the mounting holes on the bracket you have on your trailer, and they do not match the mounting holes on your F2 jack you may need to have the old bracket removed and use a mounting bracket like part # F500277 for the F2 swing-up jack with a 3 x 4 mounting system. We also have a replacement mounting bracket kit for Fulton F2 jacks. Part # F0928059-00 includes 3 inch and 4 inch U-bolts and also has lock washers and nuts. I have attached a photo that shows...

  • Bracket for Mounting Fulton Trailer Jack
    Fulton marine jacks mount to a bracket that has holes that are 3 inches apart on center, the Jack Mounting Bracket for Fulton Marine Jack - Weld-On # P9012-00. There isn't going to be a way to mount a Fulton jack to a bracket with different mounting holes. So the only suggestion I can offer is to have the new bracket welded on, and ensure your current jack will work with one that uses these same mounting holes.

  • Replacement Swivel Jack for 2005 EZ Loader Boat Trailer
    Hi Rob! The F2 series uses a different style plate that you have so you'll either have to replace your weld-on bracket or you can use the bolt-on option # F1413040134 OR you can use the adapter # F500320 to weld the F2 to your trailer.

  • Trailer Jack for Use in Off Road Conditions
    The Fulton F2 Swing-Up Trailer Jack with Dual Wheels # F1413060334 may get around better in the conditions you're camping it. It will be hard to find a jack that will move that great on soft surfaces though. The weld-on Fulton Adapter Kit # F500320 mounting holes measure 3-1/2 by 4-1/2 inches.

  • Adapter Kit for Older Fulton Bolt-Thru Jack to Fulton F2 Jack
    The Fulton Adapter Kit # F500320 will allow you to mount a Fulton F2 trailer jack to your current mounting bracket like part # P9012-00. The Wide Wheel # F1413040134 version of the F2 works on gravel. It will obviously be harder to move on gravel than on a flat surface, but we have customer reviews on both that either say or show that they have used it on gravel and it works well. The dual wheels should be easier to maneuver altogether so I recommend going that route.
