Excellent upgrade for collapsing the tongue of a trailer. I used this on a galvanized boat trailer and the install is pretty straight forward. I used a sawzall with a metal blade to make the cut (make sure all wires or brake lines are clear before cutting) and it worked perfectly. Just take your time and make the cut straight. I have towed the boat several times since this addition and there’s no issues. No play in the junction so no annoying rattling. I was very happy to finally complete this project. Makes so much more room in my shop not walking around a long boat trailer tongue and allows me to fit other items in front of the trailer if needed inside the shop.



by:

Watched a good video before I started-make sure you have good drills (16 holes)
I used a 1/4-3/8 then the 1/2 I think that helped alot. One thing I would receommend of the manufacturer that they mark the "trailer" portion of the swimg away and the "tongue" portion I was a little confused on that.
I am very happy with the results was able to get my old boat into a shed it previously was too long for I was able to shorten the tongue approx 32".
The etrailer folks were top notch with their service and ability to answer any questions I had. I only have one pic of the folded up tongue attached

Works great just like you would expect



by:

Very nicely made unit. It was slightly larger than my trailer rail but I just shimmed it with some aluminum. Just remember that you will probably have to add some extra safety chains and have a good supply of sharp drill bits to make holes in your trailer.

Awesome product to update trailer for hinged tounge easy bolt on instructions done in less than an hour

Wonderful product easy install high quality

We ordered this product for our boat trailer. My husband us extremely happy with it and recommends it to anyone with storage space issues. We are now able to park our boat in our driveway instead of storing it off site and paying winter storage fees.

Its great! Storage of boat is so much easier now, shouldnt have waited so long to buy this. Money well spent! Dont hesitate!



by:

Very well made and beats cutting a hole in the garage door ??



by:

Pretty easy to install if you have the right tools. Boat now fits in garage without needing to be at an angle and in the perfect spot. Picture is before I got the new safety chains and wiring installed. Make sure to get loom to protect the wire at the joint and possibly upgrade wire quality. I went with Wesbar 787268 and a braided wrap.



by:

Trailers great, no issues and now I have more room in the barn to close doors.



by:

I purchase items on the internet frequently. I would say that etrailer should be rated one of the highest rated websites. The product purchased was high quality, clear instructions that made the installation easy, on time delivery and, of course, the product was exactly as described on etrailer website. The trailer now fit in my garage.

The product has worked out great. Several friends commented and may have ordered one for themselves.



by:

My son purchased this product which I installed on my EZ Loader trailer. Took a few hours but I like a project. Its been great, allowing me to easily park my boat in the garage with room to spare. Just wish I had installed it earlier. When I installed, I also replaced my brakes (the entire brake plate, etc), bled the brake line and installed the flex line needed for the swing. Got all the accessories from etrailer. Great service and just recently ordered some lights as well.



by:

What a great product! And it's made in the U.S.A. Excellent quality, just as you would expect from an American made product. Fit & finish are very good, and the instructions were well detailed and easy to follow. Kit was complete with special tools needed for installation, and was not missing any parts. Took a little under 4 hours, and that included time to relocate trailer tongue jack to a new location. Looks like it was factory installed, and was considerably cheaper than adding 3" to the back of my barn. Now I can just fold the tongue (shortens trailer by 27 inches) and close both the front and rear barn doors. As the photos show, all that's left is to add the new, longer safety chains. Thanks for a great solution to my problem.



by:

Haven't put it on yet, maybe this week. I purchased a new boat April 1st of last year, knowing that I would need the coupler hinge kit to garage store it. The boat is in the garage, but I had to cut the tongue off to be able to shut the overhead door. Now I can install the coupler just in time for boating season. I knew the problem wasn't etrailer's making.

Your product was a tremendous package. The trailer I installed it on carries a 1976 Cobalt 19DV that I have owned since new. The trailer is a Calkins single axle 4000lbGW. I have paid over 15K in storage fees for the over 37 years I have owned this boat. I wasn't aware of a product like this until I happened to see a trailer at a Bass Pro Shop in Branson MO while on a vacation trip. The trailer had a swing tongue not your product but it got me thinking and after returning home I found your product on the internet. Can't believe how great the application fit and the ease of installation(after drilling holes of course). I have on single car garage that I tried to store the boat in but the tongue was to long to be able to close the door. After this installation the trailer fits perfect. Great product would recommend to anyone.



by:

Great product. Easy to install. Enabled me to store boat on trailer in garage in deed restricted community



by:

Excellent products,service and fair pri cing.

I have added the Fulton Fold-Away to two of my boat trailers and would highly recommend this product who is need of shortening their trailer tongue length. Installation was not difficult at all.



by:

It arrived missing the pin!
Called customer
service and Kim who was awesome,
Helped me out right away, package came open during delivery and pin fell out, post office did not put the part back in and taped box shut.
Within minutes of calling customer service, Kim had a new one on the way!



by:

This Fold-Away Coupler was a life saver for our new boat and trailer. We bought more boat and trailer than our barn could hold! We now have the room required to store and move about in the off season. Would recommend this valuable piece of equipment.



by:

This thing is a tank! Way more robust than I expected. Transfer punch that came with the kit was a nice touch for installation. I will always recommend etrailer to my friends for anything they need.



by:

Now able to garage boat.



by:

Bought this to fit my new-to-me boat in my garage. Installed very easily and it helps to have a second set of hands. As others have mentioned, it does have a little play up and down, but it's nothing noticeable when towing. The coupler pin sits pretty snug and there isn't any play in mine.



by:

Excellent product. They were extremely helpful in getting this ordered --'real' friendly people. All hardware, plus a centering punch and torx bit to hold the fasteners were provided. Thank you much.



by:

Works great. Would recommend product to anybody.



by:

When I'm able to get my boat out I'll come in and write a review,right now we still have 2 feet of snow on the ground.

  • Can Male & Female Castings be Reversed on Fulton 3 x 4 Trailer Tongue
    I can't see any reason at all why there would be an issue reversing the male and female castings of the Fulton Fold-Away Coupler Hinge Kit for 3" x 4" Tongue # FHDPB340301.

  • Determining If The Fulton Fold-Away Coupler Hinge Will Work With Your Boat Trailer
    The closer to the coupler you are with the Fulton Fold-Away Coupler Hinge # FHDPB340301 better it can handle the tongue weight of the trailer, but you'll get less clearance with the tongue/coupler in your garage. There are a few other things to check before starting the installation. You'll need to measure the tongue and ensure that it's 3" wide by 4" tall and that the wall thickness is between 0.188" and 0.120" thick. Once you've confirmed this you can then choose the placement of the...

  • What is the Largest Fold-Away Coupler Hinge Kit Available?
    The Fulton Fold-Away Coupler Hinge Kit # FHDPB340301 for a 3" wide by 4" tall frame is the largest we carry. This kit is rated for trailers up to 7,500lbs. You may be able to reduce the size of your tongue to still use this hinge kit if your trailer does not exceed the 7,500lbs

  • Can Fulton FHDPB340301 Fold Away Coupler Hinge Kit Be Welded Instead of Bolted
    I checked with my contact in the Tech services department at Fulton, who tells me that it is indeed acceptable to install the # FHDPB340301 fold-away coupler hinge by welding instead of bolting. If your trailer tongue is galvanized, be sure to install it in a well ventilated area as welding on galvanized metal can give off toxic fumes. I've linked you to a product description video for the # FHDPB340301 fold-away hinge.

  • How Much Up and Down Play Is Normal With Fulton Fold-Away Coupler Hinge Kit FHDPB340301?
    With the Fulton Fold-Away Coupler Hinge Kit for 3" x 4" Tongue - Bolt On - Up to 7,000 lbs # FHDPB340301 installed you will get some up and down movement. Typically this should not exceed about 5 degrees, or 1-1/2" with tongue at the longest length of 48". The shorter the tongue the less play you will notice. There is play due clearances needed to allow the hinge to be able to open and close without getting stuck. I included a video of the # FHDPB340301 for you to take a look at.

  • Can Fulton Fold-Away Coupler Hinge Kit be Used on Pontoon Trailer and Capacity When Cut to 36 inch
    As long as your trailer has a 3x4 inch trailer tongue the hinge kit part # FHDPB340301 will fit and work well. When using the hinge at the 36 inch length the capacity would be 6,000 lb total trailer weigh and 600 lb tongue weight.

  • Fold-Away Coupler Hinge Option For A 2 x 4 Trailer Tongue
    I agree with your thoughts on using a 3" x 4" Coupler Hinge # FHDPB340301 instead as well. You could just get some half inch steel plates and increase the width of the tongue enough to accommodate the coupler hinge. If you run a bolt through the middle on both sides of the coupler hinge as well then you can lock the steel plates into place without having to weld. You'd just have to snake your brake line (if you have surge brakes) around the bolts.

  • Replacement Mounting Hardware For Fulton Fold-Away Trailer Coupler Hinge

  • Availability of Coupler Hinge Kit that Could Fit 2003 EZ Loader Trailer
    We do have coupler hinge kits available but what your 2003 EZ Loader trailer would need depends on the dimensions of your trailer's tongue. The part # FHDPB330301 is for 3 inch by 3 inch tongues, the part # FHDPB350101 is for 3 inch by 5 inch tongues, and part # FHDPB340301 is for 3 inch by 4 inch. So you'd have to measure your tongue to see which option would work best for you.

  • Can a Fold-Away Coupler Hinge Kit Be Used To Extend A Trailer Tongue?
    Yes, you will be able to add the Fulton Fold-Away Coupler Hinge Kit to your boat trailer to gain some additional length out of the trailer. We have the hinge kit in different sizes to match your trailer tongue. It appears you will need the 3"X5" # FHDPB350101. We also have a 3"X4" # FHDPB340301 and 3"X3" # FHDPB330301. You will need to source the additional trailer tongue material from a local supplier in the length you are needing.

  • Swing-Away Tongue For Aluminum Trailer With Galvanized Steel Tongue
    For your aluminum trailer with a galvanized steel tongue (swing-away tongues cannot be used on aluminum tongues), you'll need a die-cast steel tongue with a zinc finish from Fulton. The correct fit is going to depend on the size of your trailer tongue, as well as the thickness of the material of your current tongue, which must have a thickness between 0.188" and 0.120". If your trailer tongue's material thickness meets that requirement you can choose from the following, based on your...

  • Will Fulton Fold-Away Coupler Hinge Kit Work on Aluminum Frame Trailer
    I do have an option for you but the fold-away trailer tongue adapters we offer cannot be used on trailers with an aluminum tongue. The adapter is steel so mating this to an aluminum tongue could cause galvanic corrosion and there is also concerns with strength. That said, many aluminum frame trailers have a steel tongue so if this is what you have or you can convert the trailer to this you'll be able to use one of the Fulton Fold-Away Coupler Hinge Kit listed below. - 2" x 3" Trailer...

  • Inside Dimensions of Fulton FHDPW330300 Fold-Away Trailer Coupler Hinge
    The Fulton # FHDPW330300 fold away coupler hinge is designed to slide over a 3 x 3 inch trailer tongue, so the inside dimension is just slightly larger than 3 x 3. To install, you'd cut the trailer tongue at the point where you'd like it to fold, slide the hinge over the tube and weld it into place. The hinges aren't intended for use on aluminum trailer frames.
