Fulton Fold-Away Coupler Hinge bolted on square and easily. Holds the weight of my boat very well and allows the boat to be stowed in my garage now. I did notice that the coupler flexes a bit, but does not interfere with the overall towing of the trailer.

I'm very happy with how this item mounted and it's performance. Good quality from Fulton.

After one year, this product is still great. Cutting down some of the tongue from my DB trailer made it wobble from side to side at speeds of over 65 mph, but once I re-mounted my spare tire and went to the recommended 10-12 of total weight at tongue weight, problem solved. Again, I only had that problem because I removed a big section of the tongue to make it a proper folding tongue.

Extremely satisfied. The price was great, the service likewise. Shipping was reasonable. I have purchased several products from e-trailer in the past and was extremely impressed with every transaction. I will certainly do business with them again, should the need arrive. I should add, in the past I've had questions about installation and their help department talked me through everything, which allowed me to quickly solve my problem.


Great product exactly as described, looking forward to fitting the trailer in my garage now.


This coupler did exactly what I needed it to. I have a 17ft Pro Angler kayak and the trailer was a bit too short. I wanted to mount a small winch to ease loading after a long day on the water, but just didn't have the room on the existing trailer tongue. I used the maximum length extension for my application (4ft) and could not be happier with the results. Installation was pretty simple... just make sure you have a good carbide bit to drill through your galvanized steel. I wasted a lot of time using an inferior 1/2 inch finishing bit which just burned up. I went to Home Depot and got a good carbide bit and it went through like butter... no issues. Just think about your wiring and all that ahead of time and make sure you have what you need. Great product so far.


I keep my boat in the garage which made for a tight fit to get into the house. I came across the Fold-Away Coupler Hinge Kit. - ordered it and installed it this weekend. The installation was much easier than I expected. Great communication from the folks at

Now the boat fits with more space to move around in the garage.
My wife is happy - so I am happy!
Great product!
Photo attached - I just have to move the chains so they connect behind the coupler.


Etrailer, was very helpful, and kept me up-to-date with my order. Thank you


The device is as described and meets the needs I have for boat trailer.


I just completed the installation of the Fulton Fold-away Coupler Hinge Kit on my Malone Megasport kayak trailer. The trailer and kayak racks were also purchased from etrailer. The trailer is great but it barely fit in my garage. My solution was to change out the crossbars from 86” to 78” and install the Fulton hinge kit. I was not fast but I have learned to measure twice and cut once. The installation was relatively easy and straightforward and the instructions easy to follow. I am glad I made the purchase!


The directions were very good and easy to fallow. I got all the tools ready per the directions and quickly got each step done. The only thing I have left to do is lengthen and remount the safety chains.

I purchased this Fulton Fold-Away Hinge Kit for a Folding Tongue to replace a rusted one on my 15 foot Mitz flats skiff. I would NOT use this item on any trailer carrying more than 1,000 lbs. there is no side to side play HOWEVER there is considerable up/down play no matter how tight you set the hinge bolt.

Thank you for your review. This folding tongue can be used on trailers with a gross towing weight of up to 5,000 lbs. There should not be any up and down play if the trailer tongue is a 2 x 3 trailer tongue. As long as the thickness of the metal used for the trailer tongue is at least .188 to .120 you should not have any issues with a trailer up to 5,000 lbs.

Just completed installation of trailer tongue hinge and could not be more pleased with the result. This saved 3ft off orig trailer length and allows boat to now easily fit in the garage - just in time for winter. Installation went smoothly - the instructions and on-site vids were extremely helpful in avoiding issues. I'd caution anyone to take heed of the safety cautions - esp. eye protection - when cutting and drilling. Results were fantastic. Hinge is a high quality, solid product - extremely pleased. Item shipped and arrived early, customer service is first rate and I will def be ordering from etrailer again. Highly recommend.


Thank you,
Great product and fast delivery
as well...
Your product looks and feels like excellent quality.... instructions and accompanying tools were excellent and help make the job a lot easier....
Thanks again


Was very happy to receive my order. All came through as expected!


Good price timely shipment and fits properly. Thank you for your excellent service


quick shipping of a quality product.


Great product, follow the instructions and you will glide right through the installation process. Finally can park the boat inside, no more boat covers!


Item was as described by Lisa. She kept me up to date until I received.


Easy to install,makes trailer smaller foot print for storage


Perfect part, works flawlessly. Very happy with this purchase. Thank you etrailer!


I purchased this to help with my storage space needs. Great quality with top notch hardware. Easy to install with clear instructions. Very happy with this purchase.


This has not changed in how it looks for the last 25 years. No need to mess with a good thing. Easy to install and solid as a rock. I extended my trailer tongue 3 feet and it still fits in the garage. Now I won't have to get my vehicle tires wet at the launch ramps.


Installation was painless and straightforward. I'm pretty good with tools so it was a no-brainer. If you need an instruction manual to figure out how to use a screwdriver you may need some help, but if you can saw a straight line with a hacksaw, use a file and a socket wrench, you are good to go. It's still a good idea to read all the installation instruction first.

The Fulton hitch hinge works exactly as advertised. I can fit my boat into my garage now and once it's closed and pinned it is a solid tow. Rock solid.


Placed the order on Monday and items arrived on Friday. It took approx 3 hours for install to my boat trailer. Now I can walk around the garage. Item is look very good. The price is very good compare with the local store. Shipping is free.


Read the instructions. Follow them as written, and in less than 3 hours you will be able to put your trailer back in your garage. And it would appear if you have any problems, etrailer would be waiting on your call. They let me know when it was mailed/ delivered and then wanted to know if I was okay. Great product and service.


I wanted to put my smaller fishing boat in the garage in the winter. No luck! The tongue of the trailer was in the way. I ordered the Fulton Fold-Away Coupler Hinge Kit and after an easy installation I will be able to have the boat in the garage where it will be out of the weather and available for me to work on for the next fishing season. Thanks for a quality product and fantastic attention to customer satisfaction. A+A+A+
