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! 558541

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. 693140

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

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. 869507

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! 796098

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 768159

Ask the Experts about this Fulton Folding Trailer Tongue

  • Can Fulton Fold-Away Coupler Hinge Kit for 3 x 5 Tongue Mount to 3 x 4 Tongue
    While you can use the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue # FHDPB350101 your 3" x 4" trailer tongue, you would not be able to do it with the Titan adapter you mentioned. Instead, to mount this hitch kit to your tongue you would need to have 1/2" spacers welded to the sides of the tongue in order to get it to work. I have added a link 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.

  • 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.

  • Length of Brake Line Hose Needed When Installing Fulton Fold-Away Coupler Hinge Kit, # FHDPB350101
    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. I have numerous sizes of flexible brake lines available and I have included a link to the available options. I would recommend to use the longest flexible brake line available, like the 25...

  • Tongue Extension Availability for Use With the 3 x 5 Fulton Fold-Away Coupler Hinge Kit
    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). Because of this we do not have any extension for your trailer tongue or one that is pre-tapped. The hinge has a max weight rating of 9,000 lbs but that all depends on where the hinge is installed. You will want to use the attached table to help you determine how or...

    If you plan was to use the Fulton Fold-Away Coupler Hinge Kit for 3 x 5 trailer tongues # FHDPB350101 with shims on a narrower trailer tongue you'd actually need to weld the hinge kit as the bolt holes aren't going to match up perfectly and it would be really difficult to make the bolt holes work like needed.

  • 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.

  • What Would Tongue Weight Capacity be Using Fulton Fold-Away Coupler Hinge Kit w/3,100 Pound Trailer
    If we go by the max pivot length chart, see picture, at 3,100 pounds the tongue weight maximum would be 310 pounds (since in the chart the max tongue load is 10 percent of the gross trailer weight). If your tongue weight is 180 pounds now then it will still be plenty low enough with a longer, folding tongue.

  • Selecting New Flexible Brake Line After Coupler Hinge Kit Install on Trailer
    You will need to shorten the existing brake line by coiling it inside the stationary part of the tongue (always coil from the top down not bottom up or sideways) or by cutting the line, reinstalling the fitting in the correct direction on the line and double flaring the end of the cut brake line. Make sure that you do not install a flexible line that is too short, which would be damaged when the coupler is opened. Also keep in mind if you install a flexible line that is too long, it...

  • 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...

  • Test Trailer To Determine If it's Aluminum for Install for Fulton Hinge Kit
    It looks like it's steel to me, but you can try to see if a magnet would attach to it. If not, then you'd know it's aluminum and the hinge kit part # FHDPB350101 couldn't be used.

  • 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....

  • 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.

  • Dimensions of Fulton Fold Away Coupler part # FHDPB350101
    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.

  • 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...

    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.

  • 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...

  • Can the Fulton Fold-Away Coupler Hinge Kit Still be Installed Inversely
    I spoke with my contact at Fulton and as long as the part that swings away when using the Fulton Fold-Away Coupler Hinge Kit # FHDPB350101 is not very long (which is doesn't appear to be) you will be just fine. If it were fairly long then you could see some deflection (or warping) in the long run.

  • 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.

  • Is Fulton Fold-Away Coupler Hinge Safe to Use for Towing
    The Fulton Fold-Away coupler # FHDPB350101 is rated to tow up to 9,000 lbs. All the parts and mechanics are safe for towing up to that weight.

  • Does Capacity for Swing Away Trailer Hinge FHDPB350101 Apply to Trailer's Weight with Boat
    The capacity of the Fulton Fold-Away Coupler Hinge Kit # FHDPB350101 which is 9,000 lbs applies to the entire weight of the trailer and it's contents. So if it's a boat trailer that would include the boat and the trailer. Also depending on where you make the cut on the trailer the capacity can be affected.

  • 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....

  • Installation Instructions for a Shorter Boat Trailer Fold Away Coupler Hinge Kit
    The length of the fold away can be shortened in most circumstances.

As an example, this means that if your gross trailer weight, loaded and ready to tow, is 7,500 pounds and the tongue weight is 750 pounds, your pivot length can be 27 inches (maximum)...

  • 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...
