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.


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


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!


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


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.


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.

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


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.


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.


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.


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.


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.


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!


Now able to garage boat.


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.


Works great. Would recommend product to anybody.


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.


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.


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.



This works great very easy to use and built strong.


Amazing, easy install great Purchase. Very heavy duty, have trailered my boat all over with it and no issues.


I ordered this product, the delivery was 6 months late. The shipping box was damaged, obviously not the fault of the manufacturer, but better shipping containers are necessary. Bolts were missing from the package, because of the damage. The product is a good product, just need to use better shipping containers.


Package showed up 2 days later and was double boxed to protect the contents. Great service!
Thank you.


Great product but not an easy instalation but necessary
