Video Transcript for Fulton Folding Tongue - Coupler Hinge Kit - FHDPB350101 Review

Today were going to review part number fhdpb350101. This is the Fulton Fold Away Coupler hinge kit for a three inch by five inch trailer tongues. This is a bolt-on unit. This hinge kit will let you create up to a 48 inch fold away tongue for your trailer so that your trailer can be stored in even the smallest garage. It is designed to be used with achewaters our standard couplers. Again it has the holes because it is a bolt-on installation.

This is designed of a sturdy steel construction and it does have a corrosion resistant, zemat 600 zinc finish. The mounting hardware is included. The pivot bolt, the pivot pin and clip are included also. This hinge kit is not for use on aluminum trailer frames. This part is made in the USA.

I do want to give the measurement. It is designed for three inch by five inch trailer tongue. That would be three inches and five inches that way. It does have a five year limited warranty. Basically what you would is you could pull the clip, remove the pin.

That would allow the fold away to swing all the way around to the side of your trailer. Now Fulton does recommend installing this that you should install this male casting which is the part with the center casting in it to the stationary part of the trailer tongue. This female casting should be installed on the fold away section of the trailer tongue. Basically now you can install this way to fold this way or 180 degrees to fold the other way. It is recommended to always mount this male casting to the stationary part of the trailer.

Now the capacity on this hinge kit has a maximum capacity of 9,000 pounds. It will vary depending on the pivot length of the fold away tongue. Basically the pivot length would be the measurement ---. Let me put the pin and cli-p back in, there we go. Now when I say pivot length that would be this fold away section. In other words your coupler achewater would be here. If you measure from the center of your coupler, or the hitch ball is connected, to the furthest pivot hole which will be this one here from the coupler. Measure that distance and if it measures 48 inches which is the max you can your weight rating would be 5,000 pounds. If it would measure the minimum which would be 27 inches pivot length then you would have your maximum weight capacity of 9,000 pounds. The best thing to do would be to go to the product page for this part number. On the bottom of the page youll see a table that will be listed. It will list whatever your pivot length is that you measure it will give you what the capacity is for that pivot length. Again this part comes with a five year limited warranty. That should do it for review on part number fhdpb350101.

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

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

Ask the Experts about this Fulton Folding Tongue

  • 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.

  • 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...

  • 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 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...

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.

  • 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...

  • 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.

  • 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...

  • 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....

  • 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.

  • 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.

  • Installation Instructions for a Shorter Boat Trailer Fold Away Coupler Hinge Kit
    The length of the fold away can be shortened in most circumstances. If you have a 3 x 5 inch trailer tongue then the Fulton Fold-Away Coupler Hinge Kit, item # FHDPB350101, can be used and the extension out front can be cut to any length shorter than the maximum pivot length listed in the chart I have linked. 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)...

  • 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.

    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 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.

It would be also a matter of measuring the tongue of your trailer as well. This kit fits a 3 inch by 3 inch frame channel but we also have weld on 3 inch by 5 inch hinges like part # FHDPB350101 which are rated even higher at 9,000 lbs.

I recommend the # FHDPB230101 for a smaller 2x3 inch tongue.
