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 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:

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:

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:

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

Perfect



by:

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:

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



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:

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:

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



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:

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.

  • Hinge Kit Recommendation for a Shorelandr Trailer with Surge Brakes
    For a 3x5 trailer tongue, I'd recommend the Fulton # FHDPB350101 coupler hinge kit. Keep in mind that this hinge isn't for use with aluminum trailer frames. You'll also need to install a piece of flex brake line like the # T0777300 that you referenced. I've linked you to a video that contains more information about the hinge.

    The Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue part # FHDPB350101 will work with an A-Frame Big Bubba Deckover trailer with a straight tongue welded beneath it. As long as the straight tongue is a 3" x 5" trailer tongue with a material thickness between .188" and .120". Please take a look at the accompanying chart to determine the maximum pivot length allowable for your particular straight tongue.

  • Is There a Fold-Away Trailer Tongue Coupler Kit for a 3x4 Trailer Frame
    I do have a fold-away trailer tongue coupler kit that will work on a 3x4 trailer frame, the Fulton Fold-Away Coupler Hinge Kit part # FHDPB350101. That said, you will need to use shims/spacers to fill the rest of the gap. This is actually explained in the instructions and very common so no need to worry.

  • Fold Away Tongue Bracket for 3" x 4" Tongue
    The Zinc Plated Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue - Bolt On - Up to 9,000 lbs # FHDPB350101 is the only option we have for your 3 x 4 inch tongue. You would need to install 1/2 inch spacers on the top and bottom of each half of the tongue to give you the support needed to be compatible with this hinge and 1/2" longer bolts will be required. I've included a link to the page and a video my buddy Rob did on it here at etrailer for you to check out.

  • Why Do Some Trailers have a Coiled Brake Line
    The pressure in a brake line is a constant regardless of whether one line is longer or not. Some people will say it is so the lines are equal length for pressure but the brake fluid cannot be compressed so the line length difference doesn't affect anything. In some cases it is easier to coil lines (in a downward spiral) than it is to have to cut and flare the lines to length. Also, with hard brake lines some of the components the lines attach to are fixed, like the frame or the actuator....

  • Will Fulton Fold-Away Coupler Hinge Kit Work on Aluminum Frame Trailer
    I do have an option for you but the fold-away trailer tongue adapters we offer cannot be used on trailers with an aluminum tongue. The adapter is steel so mating this to an aluminum tongue could cause galvanic corrosion and there is also concerns with strength. That said, many aluminum frame trailers have a steel tongue so if this is what you have or you can convert the trailer to this you'll be able to use one of the Fulton Fold-Away Coupler Hinge Kit listed below. - 2" x 3" Trailer...

  • Swing Away Hinge Kit Recommendation for Boat Trailer
    It sounds like you have a standard pole tongue trailer and are looking for a swing away hinge kit. We offer a few of these kits that are designed to fit several frame sizes. The part # FHDPB350101 will work if you have a 3 by 5 inch trailer tongue, part # FHDPB330301 will fit 3 x 3 and the part # FHDPB230101 will fit 2 x 3. You will need to measure your trailer tongue so that you can pick out the correct kit. I attached an install video that shows how a kit like this will install.

    To install the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue # FHDPB350101 you will simply need to cut your current trailer tongue so that you have the desired length that is foldable (see attached customer photo).

    To put a Fold-Away coupler on your 2" x 4" trailer tongue you are going to need to modify your Tongue. There are no 2" x 4" options available. I recommend using the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue item # FHDPB350101. This will accommodate the larger dimension your tongue has.

  • Coiling Steel Brake Line without Kinking It
    There are some simple little pipe benders that you can get at a hardware store that will allow you to bend steel lines without kinking them. You can usually do it by hand by carefully bending the line around something like a soda or coffee can. You always want the highest point in the brake line to be at the master cylinder. So when you coil the line you want it to spiral down to the wheel. Any time you are adding, removing, or replacing brake lines you are likely going to lose some fluid....

    I went out into our warehouse and measured a Fulton Fold Away Coupler part # FHDPB350101 and found that it is 7-1/2 inches in length. From the center of the hinge pins it measures 3 inches to the closer end of the hinge and then 4-1/2 inches to the other side. The overall width of the kit is 6-1/8 inches.

  • 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....

  • 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.

  • Choosing Fold-Away Coupler Hinge Kit for Trailer Over 5,000 Pounds
    Since the Gross Vehicle Weight Rating (GVWR) of your trailer is over 5,000 pounds, you will first need to choose a coupler hinge kit that matches or exceeds this capacity. Then to choose the correct fit, you will want to take a quick measurement on your existing coupler. For example, the Fulton Fold-Away Coupler Hinge Kit # FHDPB350101 is rated for up to 9,000 pounds and is designed for 3 inch x 5 inch trailer tongues. The kit will let you create up to a 48 inch foldaway tongue and it...

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.

  • 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...

  • Can Fulton Fold-Away Hinge Kit be Used on Aluminum Trailer with Steel Tongue
    If the tongue portion of your trailer is steel then yes you can attach a hinge kit like the part # FHDPB330301 which is for 3 x 3 inch trailer tongues. Or the part # FHDPB350101 which is for 3 x 5 inch frames.

  • Fold-Away Coupler Hinge Option For A 2 x 4 Trailer Tongue
    I agree with your thoughts on using a 3" x 4" Coupler Hinge # FHDPB340301 instead as well. You could just get some half inch steel plates and increase the width of the tongue enough to accommodate the coupler hinge. If you run a bolt through the middle on both sides of the coupler hinge as well then you can lock the steel plates into place without having to weld. You'd just have to snake your brake line (if you have surge brakes) around the bolts.

  • Availability of Fulton Fold-Away Coupler for 3" x 4" Tongue
    For your application you'll need to use the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue # FHDPB350101 and then just use 1/2" shims to take up the extra space on either side. For some reason the 3" x 4" option has been discontinued by Fulton (June 2020) so that exact fit isn't available.
