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.


Comments
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.

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.

I’ve had this installed one year, and used it in salt water twice and freshwater twice, and rinsed with a hose after each use. Other than that it has sat uncovered in my driveway, and already it’s rusting very heavily. The trailer and bunks are all galvanized steel, and all older than the folding coupler, and none of them have corroded under the same conditions. For what this product costs, I’m pretty disappointed because it looks awful and now that it’s rusting, there’s not a ton you can do with it to stop it. To effectively paint it, I’d have to remove it from the trailer to get paint on all sides. I built a similar hinge for my last boar and fabricated the hinge myself with a mig welder and steel and I purposefully spent a lot on this coupler because of the galvanizing, but it’s rusting about as fast as the painted steel one did. Other than the rust, it does work the way it’s supposed to. It’s definitely got more slop in it now after not much use than it did when it was installed. It requires a lot of large drill holes to install, which is a real pain in the butt, but I guess that’s what makes it secure. I don’t think I’d buy it again based on the rust. At the very least, paint it with several coats of rust preventative paint before you install it.

I have a pontoon boat, I have had a problem launching my boat, having to put the tow vehicle to far out in the water, I was looking for a way to extend my trailer tongue a couple of feet, I saw an ad for the Fulton coupler, I ordered a unit from etrailer, free shipping and delivered on time, plus was surprised to see the quality construction of the product, would recommend the product and the service of this company.

This is without a doubt, and amazing product. I was more than hesitant to buy it. The idea of cutting off my trailer tongue and putting in what appeared to be a small hinge scared me to death. I had to cut the tongue to fit it into my condo garage, so I did go ahead an buy the Franklin tongue kit. After it came, I saw it and installed it on the tongue. It worked great and does exactly what it was designed to do. I am very happy with it's ease of use, the way does hold the trailer tongue solid, and it has no effect on towing. It is a nice tight strong connection.


Comments
It was a great buy. First I doubted if it would actually work, but. It works awesome!!!!! No problem flipping it in place and hooking up.

I was very nervous about cutting off my trailer tongues, but my new home had CC&Rs and they had to fit in the garage. I was so impressed with not only how sturdy this is, but the fit was perfect and it even included a special punch to ensure the drill hit the center of the mount holes. This was a great buy... X 2.


Comments
This message is timely since I have a related question. I bought two of these from you. One was to repair a snowmobile trailer that the tongue had snapped on. I cut out the bad piece and installed the hinge and it works great. I really appreciated the fitted punch they included to ensure the holes drilled lined up perfectly with the holes in the hinge. The second one went on my boat trailer when I bought a home where I had to keep the boat inside the garage and it also works great. Problem is, this trailer had a hydraulic surge brake coulple and in cutting off the tongue, we cut right through the tubing. In any case, it would not have worked because the rigid tubing would not have worked with the hinge. I’d like to get the brakes working again. Do you have a solution for that?
Doug - 07/02/2018

Thanks for the follow up and reply. You could use a flexible brake line hose at the hinge point for the folding tongue. I have have included a link to the current offerings that we have for flexible brake line components for your reference. You would need to select a flexible line that is compatible with your existing brake line diameter.

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.



- FHDPB340301

This hinge was exactly what I was looking for. My boat would not fit in the garage straight in or even at a shallow enough angle to park a car next to it. After a couple of hours of labor(FUN). The boat fits nicely on its side of the garage. I like projects that are rewarding once completed. The hinge is beautiful, and looks like it belongs on the trailer. The quality of materials was remarkable, and the fit was perfect. I have no concerns with this product failing whatsoever. Be careful not to cut your trailer wiring when sawing through the tongue. I needed a new plug on that end anyways, so no heartache here. I have read another review that stated this hinge was not sturdy and rattled. The only explanation I could see with the reason for that is not installing the rubber stoppers on the hinge per the instructions. The fit after installing the rubber was snug. It takes a little effort to close the hinge with the rubber stoppers installed and results in a tight connection. The picture of the product on this website shows the nuts on the top and bottom (outside) of the hinge, in the instructions it has you install them the other way, which leads to a cleaner looking end product. I will tell everyone I know that owns a boat about this product.

Great product, built very strong, took me a couple hours to install, it would have gone faster had I a better quality 1/2" drill bit! Fit and finish is excellent, it's nice the torx and center punch are included. Saved me 20" making it easily fit in the garage!

This swing tongue adapter is easy to install. The hard part is getting the nerve to cut a trailer tongue off. Be sure to triple measure the internal distance needed to slip over the tongue or follow the instructions carefully, they are correct. I put this adapter on my 16' fishing boat trailer, total weight of about 1700 pounds loaded, so pretty light weight by boat standards. There have been no issues with the hitch. After the parts wear in a bit you can snug down the pivot bolt a smidgen to take up any slop that may have settled into the joint after some highway use. The little rubber standoff grommets that are used in the locked position don't want to stay in the holes so be careful not to lose those or install something else in those areas if needed. It is a good hitch that allowed me to leave my boat in my garage rather than a storage lot or outside in the elements to weather away. I recommend this hitch to anyone in a similar situation.

I installed this Fold-Away coupler on my boat trailer and extremely happy with the construction plus ease of assembly. Marking the holes is the most critical and C-clamping part to trailer is best way to ensure no movement via transfer punching. I would suggest having sharp drill bits up to 1/2" required and step the bit size up as recomended. I used a 1/2" drill with added handle becuase the larger pit can and will bite before finishing hole. The kit comes with tranfer punch and needed T55 bit. Very impressed on quality and the room this fold-away saves me. E-trailer shipped fast and placing my order was easy. Thanks!

Very sturdy and well made. I boat all winter in Washington State so you don’t want to get your feet wet launching on icy morning. The rubber pad keeps your feet from slipping. For my trailer needs, it works well.



- FHDPB340301

It swings just fine. That said, it sags at the pivot. Looks weak but no problems so far. By the way I upsized the tongue from 3x3 to 3x4 to try and address the sag. Tongue weight is 15 percent. Perhaps a longer knuckle joint or tighter fit would help. I suspect the weld on doesn't have this problem. Overall it got the trailer in the garage but I'm glad I don't tow it very far/often.

This is a great product in concept, but not in execution. My friend installed one, which I liked. I needed to shorten my trailer by a few inches so I bought the kit too. I was able to shorten the trailer by 24 inches instead of only a few inches. When all was installed I tested it out, and the darn thing has so much wobble in it that I can easily get 1/2"-1" of up and down wobble at the coupler only 24 inches away. The casting and pins aren't a tight fit, and therefore the rating of the product is poor. I'm very disappointed and now I have a connection that scares me when I tow it. Not worth the convenience.

I received this Fulton fold away coupler hinge kit and I am very happy with my purchases. I ordered it the week before Christmas and still received it in 2 days (free shipping). This product is very well constructed, has everything you need to install it with easy instructions. They also have a very good installation video online. This is the first item that I have ordered from etrailer.com and I am really impressed with their service and product. Good job and Thanks......Tim B

Arrived on time and was exactly as described. Easy installation and works perfectly for my double axle pontoon boat trailer. I would recommend this product to anyone needed to reduce their trailer tongue length. Absolutely zero operational issues, it is tight when locked into place and no noise at all.

  • 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.

  • 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 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.

Personally I would go with the Fulton Fold-Away Coupler Hinge Kit for 3" x 4" Tongue - Bolt On - Up to 7,000 lbs # FHDPB340301 since you are only adding 12" of pivot length.

  • Inside Dimensions of Fulton FHDPW330300 Fold-Away Trailer Coupler Hinge
