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!



by:

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.



by:

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.



by:

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!



by:

Customer service at etrailer is great. I had a problem with my order getting lost by UPS and etrailer took care of me. Also, great products!



by:

Easy install, works great now boat fits in garage.



by:

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



by:

This coupler works a designed. Installation was fairly easy. It did take apx 6 months to get it which is no fault of etrailer. There was an issue with shipping. It was shipped in the original factory box. That box apparently fell apart sometime during shipping and was reboxed by the freight company. Some hardware was missing when I received it. I was able to find the missing hardware locally at my expense.

I hate to hear you were missing hardware Dana! I sent your review over to customer service to assist you.

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.



by:

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 !!!



by:

Package was wrapped in packing tape due to parts of box flaps missing. Upon opening, less than half of contents were in the box. I called customer service to explain what I received. I needed the parts for a Labor Day weekend project, and had borrowed tools for the task. Was told by customer service that a replacement could not be shipped overnight, as they do not have that capability. I was told a complete replacement would be shipped, and I would receive it the following week. All at no additional charge, except I would need to use a return label, seal the torn box, and take to a UPS office for return shipment. No credit, discount, or incentive was mentioned, nor offered. Just wait until next week, rewrap torn box, and take time to deliver it to a UPS office. Horrible process and poor customer service. I would have offered some type of credit for my inconvenience, and have someone pick up the package instead of me having to take it to UPS.

Perfect for space needed. Heavy Duty!



by:

Easy to install and works fantastic. I would recommend this to anyone needing to add a breakaway on boat trailer for space.



by:

I have a 2012 Toyota Tundra and I recently bought a pre-owned Leer camper shell. I used this harness to wire up the third brake light. I also used the brake light module. This setup worked perfectly and resulted in a neat and clean professional installation. Thanks etrailer, you had everything I needed for a successful prefect installation.

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

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



by:

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.



by:

The kit was complete, easy to follow instructions. No more lifting and inserting removable old style tongue.



by:

Install was easy, Now boat and trailer fit in garage, easy to swing into position, and swing back out of the way.



by:

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.



by:

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



by:

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 etrailer.com impressed me very much, Thank you, will order from again with out a second thought.



by:

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



by:

The swing hitch was everything I hoped for, and makes storing my boat so much easier.



by:

Great rugged product. Installation not the easiest. would suggest making center punch long enough so you can punch bottom of tongue so it can be drilled from the top on the boat side of the tongue.
Reason for the unit is to make clearance so I can fit both boat and car under canopy.
Delivery was super fast, Thank You

    You could use the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue # FHDPB350101 on a 3 inch by 4 inch trailer frame but you'd want to have 1/2 inch spacers welded to either side of the frame to take up the extra space.

  • 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...

  • Tongue Size on Fulton Fold-Away Trailer Coupler Hinge Kit, Part # FHDPB350101
    The Fulton Fold-Away Coupler Hinge Kit, part # FHDPB350101, is intended for use on steel (but not aluminum) boat trailers that have a tongue size of 3 x 5 inches. Yes, this is the internal dimension of the two coupler halves. When installed the two halves of your trailer tongue will each slide into one half of the coupler. I contacted Shorelandr and confirmed that your steel trailer PT2440T has a 3 x 5 tongue (about 78 inches in length); this will mate properly with the Fulton coupler....

  • Attaching the Titan Hydraulic Brake Line When Using Fulton Fold-Away Coupler
    When using the Titan Hydraulic Brake Line # T0980100, there are fittings included to attach to your current brake line. One end of the brake line has a female fitting. This female fitting will attach to the male fitting on your brake line. You would need to coil the existing steel brake line in trailer frame behind where the Fold-Away Coupler # FHDPB350101, installs. So basically the Titan Line is adding an extension to your current brake line so the trailer tongue can fold. The other...

  • 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. Fulton also makes bolt on hinges for a 3 x 4 tube, part # FHDPB340301 or 3 x 5 tubes, part # FHDPB350101. I've linked to a product...

    If your trailer has a surge brake coupler you will need to install a flexible brake line like the Titan Hydraulic Brake Line with Fittings - 25 inch Long, part # T0980100, inline with the couplers master cylinder and the original brake line so the tongue can fold without damaging the braking system.

  • 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.

  • How to Use Fulton Fold-Away Coupler Hinge Kit for 3 x 5 Tongue on 3 x 4 Tongue
    There isn't an option for a swing-away coupler on a 3" x 4" tongue, but you can still use the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue # FHDPB350101. In order to use this kit on a 3" x 4" tongue, you would simply need to have 1/2" spacers welded to both sides of your trailer tongue. I have added a link below to a video review for you to check out as well of the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue # FHDPB350101.

  • 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.

  • Which Side of the Trailer is the Pivot Bolt Installed On When Using a Fold-Away Coupler
    According to the instructions for the Fulton Fold-Away Coupler Hinge Kit part # FHDPB350101, the pivot bolt is installed on the left hand side of the fold-away and the hinge pin is installed on the right hand side of the fold-away. However, I do not believe it matters. If you wanted the tongue to swing to the left side then you would place the pivot bolt on the left side and vice versa for the right side.

  • Flexible Brake Line for a Trailer with a Folding Tongue Coupler
    The Titan brake line # T0980100 is 25 inches long and should work for you since you are adding the reverse electric lock out. You will want the flexible line to be long enough to not bind or put stress on the rest of the brake lines when the coupler is folded in. It will need to go from the back of the master cylinder, or in this case back of the lockout solenoid, past the hinge.

It can be rather difficult to just look at a bolt or hinge pin and determine whether or not it has stretched or deformed but I would be willing to bet that is the issue you are having.

  • Fulton Fold-Away Hinge Kit Recommendation for a Trailer Carrying a 1800 lb Pontoon Boat
    There are a couple factors you need to consider when determining what the maximum pivot length you could use on your trailer. You will need to consider the gross vehicle weight of your trailer as well as the maximum tongue weight that the trailer will see. The reason you will need to consider these factors is because the more of the tongue that is beyond the folded portion of the Fulton Fold-Away Hinge Kit the more leverage the weight of the trailer will have on the hinge and the easier...
