This is really going to save steps and my shins. It took 8 months to recieve this part due to being back ordered from the manufacturer. Installation took around 3 hours and other than drilling 16, 1/2" holes, was easy. The delivery company was brutal with the package delivery, the box was broke open and the hinge pin was left out when box was taped closed. Ed W. Jumped on replacing it without hesitation and it should be here soon. Thanks Ed and Bailey B. For being on top of things so professionally.


This was a must have for us to be able to fit our boat in the garage. I am very pleased with the results and how great of quality this product is. After one year still looks great, no signs of wearing off. etrailer knowledge and professional customer service made our purchase experience easy.


I actually ordered this like 4 months earlier online and was constantly told it was on back order from a different company. I cancelled order and ordered from ETRAILER and it was shipped within 24hrs and arrived just a couple days later. Everything arrived as ordered and will be mounting in the next week.


I haven’t installed it yet, but product appears very high quality. Also they have excellent customer service and have dealt with a couple of shipping issues I had in a very timely manner…


The Fulton Fold-Away Hinge Kit Folding Tongue which I purchased for my pontoon boat trailer was recommended by a local trailer supplier. My trailer tongue was three feet too long to fit into the storage unit I used for the trailer and I needed a way to shorten the trailer without making major changes. The Hinge Kit was the answer and the only difficult part was cutting the steel trailer tongue so that I could attach the hinge. I was very impressed with the kit and the way the instructions led me step by step with the installation.
The job took about four hours and the finished product allowed me to fold back the tongue once the trailer was in the storage unit without any difficulty.

It is working great and is exactly as described ... it allows me the extra room I need when I put the trailer into storage.

This is an excellent item that gives me an extra 2 feet in the garage which is a big deal in my cramped space. Straight forward installation was no problem just make sure your holes are drilled correctly. They do include a drill punch with the kit which makes marking the drill points a snap! Haven't towed yet but looks stout enough to have no problems. Thank you!


Good solid product for people who need it.. To bad you lose almost half the carry capacity by shorting the tongue...


Perfect for space needed. Heavy Duty!


This is the second Fulton swing tongue I have installed on a boat trailer. I installed one on a 3x3 tongue about 10 yrs ago and have towed that boat between MI and FL each year with no issues. Installed the 3x5 model on a new boat trailer 2 days ago. This trailer tongue was much thicker steel and was more difficult to cut and drill. The only issue encountered was the corners of the interior channel of tongue were slightly rounded. The holes for the bolts were close to sides of tongue and nuts with built in washers did not want to seat flat against steel due to that. This was fixed by grinding off the washer part of nut on one side and putting that part against the tongue sidewall. It was just a little more work. They tongue hinges are great to enable you to put your boat on the garage and still walk around it. Highly recommended!




Good product. I’ve used it in past with great results and love extra space it creates

works great

This has made my boat trailer easier to park because I can back into garage and fold away but is also locks up better. I would do it again if I replaced my trailer


This hinge did everything I needed it to do!


As usual with etrailer, service was excellent. The product too seems to be exactly what I need, but I won't be able to find out until spring when I pull the boat out of storage. Appears to be well built and should fit well. Roger

Product is excellent. Works great. Customer service is second to none !!!

Using etrailer was very easy. Was my first time ordering from them. Greg was knowledgeable and very helpful. Most of all, I had been searching for a bolt-on foldable hitch for over a week with everybody either out of stock or projected 8-10 week lead times......etrailer had the part I was looking for in stock. Also, the part arrived a day earlier than projected. Overall, very good experience. Highly recommend using etrailer.


Shipping was fast, a real quality product. I'm a do it yourself kind of guy, I found this very easy to install by myself with a few simple jigs. The hardest part was pulling the brake line forward to flare it and finding someone to make up a flexible line. I would recommend this product.


I am extremely pleased with the service I received. It was easy and arrived on time
I highly recommend

Very impressed with product, excellent instruction included torx bit for installation and centering punch to mark holes, that was very thougtfull of Fulton. Used sawsall to cut 3x5 tounge on Shorelander trailer with very good success. The instant shipping from impressed me very much, Thank you, will order from again with out a second thought.


Exactly what I was looking for, works g reat!


Excellent people to deal with Shipping was fast and prompt I will use them for all my trailer needs Thanks


Product was very well made and etrailer's sales personnel communicated very well throughout the process. I would definitely use this company again.


This is a great product. The extra room with the folding tongue, makes putting away the boat much simpler. When I was installing it, my cut on the tongue wasn't perfectly straight, but it was not a problem, the way the product is designed. I would recommend this over weld on conversions.


my boat is a tool for fishing . one problem with anything and it gets replaced. this product goes on all of my boat trailers.


i highly recommend this product. i needed to shorten my boat hitch so i could put boat in garage. It works great.


Good price and product was exactly as ordered. Great product, easy to install. Came with a center punch and a torx bithe. works great!
