Video Transcript for Fulton Fold-Away Coupler Hinge Review

Speaker 1: Today we'll be having a look at the Fulton Fold-Away Coupler hinge for three inch by three inch channel tongue trailers, part number FHDPB330301. If you have a boat trailer like this or any other trailer that has a long, straight channel tongue on it such as this one, and you want to store it in your garage and have room to walk around, or be able to close your garage door to protect your investment, operating it is very simple.We'll simply pull this clip out, pull our pin out, then we can swing our tongue to the side. Now we can close the garage door. One nice feature about it is that we have these rubber bumpers that will prevent any rattling or prevent any damage as we swing it closed. You can see it's nice and quiet. Reinstall our pin.

As you can see as I try to move it along the pivot point, it's not moving. It's a very solid construction. So we don't have to worry about it rattling or our trailer swaying side to side as we're going down the road.Many of our customers have also been impressed by how well the finish holds up on it. Some have said even after a year of using it on their boat trailer, there wasn't any rust on it. Now, in order to help fight rust, the entire unit is coated with a zMAX 600 zinc corrosion resistant finish.

This is designed to work with three by three inch square channel tongue trailers. Now, keep in mind the length of your extension can reduce the amount of capacity that the Fold-Away unit offers.So, there's a few measurements you can keep in mind. From the center over where our ball goes into the coupler, to the furthest of our pivot point locations, can be a maximum of 48 inches, and the minimum recommended length is 24 inches. At 24 inches, we have the full 5,000 pound capacity, and the full 500 pound tongue weight capacity. At the maximum recommended length of 48 inches, from the center over where our ball goes into the coupler to our pivot point that's furthest away from the coupler, our capacity goes down to 260 pounds tongue weight, and 2600 pounds max gross trailer weight rating.

So, just something to keep in mind.Now, if you have a hydraulic surge coupler on your trailer, that's not a problem. You can still use a swing-away coupler without a problem. The only thing you need to make sure you have is a rubber brake hose that goes inside the pivot point, so you don't have to worry about the metal line becoming bent or breaking. Now, when comparing this to other fold-away coupler hinge kits for a three by three inch channel tongue trailer, is the Fulton Fold-Away Coupler hinge kit with a weld-on design. Now, when comparing this to the weld-on design, this one is a much easier install because you don't need to worry about welding it.

You can simply bolt it into place.Now that we've gone over some features, we'll show you how to get it installed. Now, typically, when you're installing a fold-away coupler, you're doing that so that you can shorten the length of your trailer so you can close it inside of your garage or take up less parking space. Now, in our application, our customer has a trailer that's already short, but wants to make it a bit longer so he can carry longer kayaks on this trailer. So we'll be adding a section of metal into our trailer.Now since we're adding length to our trailer, we're going to have to remove our bolt on coupler right here. Normally you can leave this in place if you're just cutting your coupler to add a hinge point to it. Now since on our trailer, where the coupler was we have some existing holes which are going to interfere with the new hinge and it was also torn here on the front, we're gonna cut off a small section. So we'll just use a cut-off wheel to remove this small section of metal.Alright, now that we have our end cut off and we have some nice clean edges, we'll take some spray paint to help prevent rust. Okay, I went ahead and made our marks where we're gonna drill out for our safety chain on our trailer, we just follow the instructions to find the correct location. We'll make a pilot hole and then we'll enlarge it. We'll do the same on the other side. Now we'll take the male end on our fold-away unit and we'll slide this onto the trailer end of our tongue.Okay, we'll just drive it on until it's straight and it hits our stop right here. You just go around on the perimeter of it, there's these stops in a couple spots, so once it's hitting all of those, you know you have it on straight. Okay, now since our fold-away trailer side is really on here snug, we don't need to worry about clamping it in place. If yours is loose, you can clamp it in place, use a center punch and mark the centers of your top four holes, then remove it and drill it out. But since ours is nice and tight, I'll just go ahead and drill right through the center and make a pilot hole at our four top locations.Now we'll enlarge our pilot holes to the size indicated in the instructions. Now we'll take our bolts and we'll place them through the top. Now we'll take our flange nuts, place them inside the coupler and throw them onto our bolts. Now we'll use a wrench to hold the nuts still as we tighten the bolts. Okay, now we'll torque these bolts to the amount specified in the instructions. Now that we have our hardware torches back on the top, we'll repeat the same process of drilling our holes and installing our hardware on the bottom.Okay, now that have the male end fully bolted to the section on our trailer that's not going to pivot, we can do the same process on either the section that we cut off, or in our case, the section that we're adding. So, we'll take the female end, place it over . Now in this instance, since this side's actually loose and we didn't have to hammer it on, we're gonna use the included punch to mark our location where we're gonna drill our holes. Step one there. We'll do the same in the other three locations on the top.Okay, with those four marks, we can slide it off and make our pilot holes. Now we'll enlarge our pilot holes. We'll slide the flange over, insert our hardware. Alright, we'll insert our flange nuts. Keep in mind this is the same hardware as we used earlier. And now we'll torque our hardware. Now that we have our hardware attached to both sides, we can attach our tongue to the trailer itself. Now, our pivot point is the side furthest away from our trailer, so it's this one right here.We'll take some white lithium grease or grease of any sort and lubricate inside where the bolt goes. We'll do the same on the tongue side as well, and slide it over, and we'll drop our bolt through. We'll now take our nylon lock nut and we'll thread it onto our bolt. We'll now tighten down our bolt. Now we'll take our pin and drop it through and secure our coupler. With our pin in place, it'll make it easier for us to torque our bolt to the amount specified in the instructions.We now have the tongue swung open and we can place our rubber bumpers into the holes here. Just push these into place. Maybe use a screwdriver sometimes to help push them in, but if you twist the same time as you push, they go in fairly easy. Now we'll go ahead and reinstall our coupler. Since we added length to our trailer, we will have to drill new holes, but if you are just putting your fold-away coupler onto an existing trailer, you don't need to worry about that, your coupler will already be on the part that you cut off. And that completes our look at the Fulton Fold-Away Coupler hinge kit for three inch by three inch channel tongue trailers part number FHDPB330301.

This is a great product! Very well made, easy to install, and the convenience of folding the tongue out of the way is by far it’s greatest selling point. The hinge was designed to be stronger than the tube itself, and it truly is. I have absolutely no fear of it failing. My only regret is that I don’t own the patent on this product. 572113

I recieved the coupler last night and install it today. It was top quility and every thing I needed came with it. It is going to save me a lot of money in storage bacause the boat will fit were it couldn't before. 8202

This product was exactly what I needed to fulfill three objectives: 1) I needed to lengthen the tongue of my trailer and yet fit the trailer and boat in my garage too. 2) The longer tongue allows me to keep my wheels out of the water, especially since the drought in CA has necessitated going beyond the ramps. 3) I find that a longer tongue makes it easier to back the trailer and is better for towing. The product is very sturdy and easy to use. 266833

Installation was easy. I installed it in a Shorland'r trailer. It took me about 2 - 3 hours including clean-up. I am 100% satisfied! All the hardware, Torx drive, prick punch and safety stickers were included. Instructions were clear and easy to follow, but I was surprised it called for torque of 75Lbs. on each bolt. Tools used were a pencil, square, high tension hack saw (18TPI), file, prick punch (included), hammer, safety glasses, 18V portable drill w/ 1/8, 1/4, 3/8 & 1/2 bits, Torx socket (included), 3/4 box-end wrench, 12" adjustable wrench & torque wrench. I also added a sheath to the wiring to reduce any chaffing that may occur across the new hardware. You may want to consider additional safety chains depending on haw far back you reinstall them on the tongue. One other note: The 3x3 box tube tongue on my trailer was a bit small. The coupler easily slid over the 3x3 box tube. I had to draw up the bolts to ensure a tight fit. I used a large adjustable wrench on the Torx socket with a small length of pipe on the end of the wrench (for mechanical advantage purposes). It drew up and tightened just fine. Overall, it was an easy install. It did exactly what I bought it to do! 62289


Comments

Scott, I am considering buying this item. Your trailer appears to be similar in stature to mine, a Karavan 1500 roller with a 16 lund. Fulton calls out .122 inches minimum thickness for the tongue and mine mics out at only .106 inches. I called Fulton and their tech dept. would not recommend the install due to liability of course. My tongue length would be 2 or less. I was wondering if you checked your tongue thickness and if it may fall short like mine does? If so since youve had yours for a couple years now, have you noticed any issues? Slop or play in the bolt connections, or anything similar that would go to steel thickness? I am considering installing anyway and I would value your in the field experience especially if your steel happens to be a bit skinny also. Thanks.

Hi Ken:I do not recall putting a micrometer on the wall thickness. I think I got it off the Shorlandr data I had in the manual or on-line. Nevertheless, in my comments I did note my box tube was a bit small and had to use some mechanical advantage to draw it tight.I never had any issues whatsoever with any of the Fulton hardware or installation. Everything works perfectly. It has been rock solid. I would not be too concerned with your wall thickness as the boat, motor and trailer are not all that heavy. It will certainly not over stress the Fulton hardware. If you were maxing out the weight limits I might be more concerned.Good luck!Scott...

Bought a used boat and it needed to fit in the garage. This was the best option and it turned out great. The product details were a big help for the fit and installation. Took about 2 hours and make sure you have a good bit to drill the holes. I stumbled on to etrailers website and no need to look any further. It's hard not to get the right part with all the details and pictures they provide. I have bought several items and the quality is high, price is fair and ships on time. I've sent my buddies your way and I'm working on another order...Thanks! 57439

I have installed my hinge and all went well. I haven't had a chance to take it out and pull it down the road, but I suspect all will go well. The installation went well and it was actually pretty easy to put on. I have included a few pictures of my install if you need them for anything. Thanks 388519

It is still working well. I dont use my boat a lot but the hinge does just what I wanted it to do. I can now fit the boat in my garage and close the door since I can collapse the tongue of the trailer. Thanks for your followup

Best accessory yet for my 17' Tracker & trailer. Fits nicely in my garage now. Installation, although time consuming, was easy - the directions were spot on. Now I just need to get extensions for my safety chains so I can mount behind the fold-away bracket. Would recommended this for anyone needing to take advantage of the limited space. 98097

Product was exactly as represented. Well made, and a perfect fit. This bolt on version (there is also one that can be welded) is a pretty big job especially if you are working alone. You'll need some high quality drill bits and several hours of working time, but the end result is worth the effort. If space in your garage is a problem, this may be the answer. It will fold the trailer tongue out of the way and save approximately 24 to 30 inches of trailer length. Allowed me to get my boat into the garage and out of the weather. 391615

This has been an excellent product. You’ll want to have a good drill bit and a heavy drill (3 inch square tube trailer tongue) for the installation but this is a one person job. This tongue joint is probably stronger than the rest of the tongue on my boat trailer. If you need to fold a trailer tongue for storage this is the only route I would take. Buy this product, because it works. 603446

The hinge is very good quality. The only thing I saw in the instructions was the picture on the box was upside down from instructions. I liked the way it was mounted on the box so I turned it over.

I would try to just make sure that you are not exceeding the weight capacity of this product and that you have all of the hardware torqued to the correct specs indicated in the installation instructions.

Solidly built product, fairly straightforward installation. One issue is the part did not have the holes in it for the dampening plugs it came with (little rubber bumpers sandwiched between the swing ends). I had to drill two 1/4 holes in the cast piece which ruined two drill bits... 520664

Do you have a question about this Folding Tongue?


  • Using Surge Brake Actuator on Trailer with Fold-Away Coupler Hinge
  • If your trailer is equipped with a fold-away coupler hinge like # FHDPB330301 then you can still use a surge brake actuator like the excellent Titan Zinc-Plated # T47154107K. The only thing you will want to add is a flexible brake line across the hinge like the Titan # T0776500 to accommodate this function.

  • Can Fulton Fold-Away Coupler Hinge Kit be Used to Extend Short Trailer Coupler
  • The Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 referenced in your question can indeed be used to extend the short tongue on your boat trailer, as long as you follow the tongue and gross trailer weight ratings based on your pivot length (like you mentioned). Doing this may very well reduce your trailer's current capacity, but as long as you remain under the reduced limit, you can do this without issue. This particular kit is designed for 3 inch x 3 inch trailer tongues. You will...

  • Adapting Folding Coupler for 3 x 3 Trailer Tongues for Use on 2-1/2-Inch Trailer Frame
  • Since we do not offer a folding coupler designed for 2-1/2 x 2-1/2-inch trailer tongues you can use the Fulton folding coupler # FHDPB330301 along with shims to make up the 1/2-inch difference in trailer tongue height and width. The material you add to the trailer's tongue should completely fill the mounting area on the folding coupler so that there is full contact between the tongue and the interior of the coupler. These shims should be welded into place by a qualified welder. This...

  • How To Determine Where To Cut The Tongue When Installing Fold-away Trailer Tongue Hinge
  • To measure for a fold-away trailer tongue hinge you want to first measure the size of your trailer tongue, for example Fulton Fold-Away Coupler Hinge part # FHDPB330301 is for 3" x 3" trailer tongues. To determine where to cut the tongue, you want to go by the gross trailer weight rating of the trailer which gives you the max pivot point length in inches. The measurement is from the center of the coupler ball pocket to the desired length as long as you don't exceed the max pivot length...

  • Where to Attach the Safety Chains After Installing the Fulton Fold-Away Coupler Hinge Kit
  • You will need to locate the safety chains before the cut that is made to install the Fold-Away Coupler Hinge, # FHDPB330301, to be in compliance with DOT regulations. Normally the chains are welded to the bottom or side of the trailer framing, and ran forward. I would have a qualified weldor, weld a Safety Chain Loop, # E950, to the bottom of the trailer frame, before the fold way cut, and then attach safety chains, like part # 2118-348-04, with Safety Chain Quick Links, # 2114-553-04....

  • Can Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 Be Used on Aluminum Watercraft Trailer
  • The Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 that you referenced cannot be used with an aluminum-frame trailer. This is true for both weld-on and bolt-on kits. The issue is not due to difficulties related to welding aluminum (though this would be a separate concern) but rather has to do with welding different metals (with different melting points). Steel-frame trailer tongues have the rigidity and strength to allow use of a folding coupler but an aluminum trailer tongue does not.

  • Availability of Folding 3 x 3-Inch Trailer Tongue Coupler for Aluminum Trailer
  • We do offer a number of different fold-away couplers for various sizes of straight trailer tongues but these are intended only for use on steel trailer frames. Aluminum trailers, for all their good non-corrosive and lightweight nature, are simply not strong enough to allow the attachment of a hinged tongue mechanism like # FHDPB330301 and the others shown on the linked page. You can make absolutely sure by contacting Shorelander with your trailer's VIN number. As the maker of your trailer...

  • Can Fulton Fold-Away Coupler Hinge Kit Work in Aluminum Boat Trailer with Galvanized Steel Tongue
  • I spoke with my contact at Fulton regarding the Fold-Away Coupler Hinge Kit # FHDPB330301 referenced in your question. He stated that as long as the tongue on your aluminum trailer is indeed constructed of solid, galvanized steel, you can use this hinge kit without issue. This will be a bolt-on installation and is designed for 3 inch x 3 inch trailer tongues. I have attached the complete installation details along with a short video demonstration on this product that you can also check out.

  • Installation Tips When Installing Fold-Away Coupler Hinge Kit, Part # FHDPB330301
  • Any drill bit designed for drilling through metal will work, although tungsten carbide bits are the best (although pricey). Here are a few tips for drilling through metal. Start with a small bit, drill a pilot hole and switch to an intermediate sized bit, followed by the final diameter. Drill at a slow speed, while applying steady pressure. I suppose you could use a hacksaw to cut your trailer tongue, but it would take quite some time and many, many blades. Your best bet would be to...

  • Availability of a 2 to 3 Foot Fold-Away Trailer Coupler Hinge with Attached Coupler
  • If you are needed a coupler and tongue that is already attached to a fold away hinge, we have # T4839000 for hydraulic drum brakes or # T4839100 for hydraulic disc brakes. These couplers will fit a 3x3 tongue using 2 of the spacer # T4842100. The pivot length is 21-1/2 inches long. But if you are looking for a 2 to 3 foot extension to the tongue you have, you will need to have a qualified welder in a machine shop of shop that works on trailers fabricate an extension for you.

  • Can Fulton Fold-Away Coupler Hinge Kit be Installed so Trailer Tongue Folds Upwards
  • The Fulton Fold-Away Coupler Hinge Kit for a 3" x 3" Tongue # FHDPB330301 is designed so that the tongue folds away to the side of the trailer. I reached out to my contact at Fulton who confirmed that you shouldn't install it so that the tongue folds up. This would likely be putting too much stress on the hinge bolts as they would be taking on the tongue weight and since this wasn't tested under these circumstances it isn't advisable to use it this way.

  • Can Hinge Kit be Used on Boat Trailer Pulling Veranda We Pontoon Boat
  • I looked up the weight of your Pontoon boat and it looks to weigh around 3,500 lbs which means that as long as your boat trailer weighs less than 1,500 lbs like the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 would be rated properly. 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.

  • Trailer tongue size for fold away coupler
  • The Fulton Fold-Away Coupler Hinge Kit, part number FHDPB330301, will fit 3 inch by 3 inch tubing. Since the hinge would slip over the tubing, the thickness of the tubing would not present a problem.

  • What Type of Sawzall Blade Should be Used to Cut Tongue on Steel Trailer for Fold-Away Kit
  • I would try using a carbide blade with your Sawzall for cutting your steel trailer tongue. If you don't already have one then you should be able to acquire one at your local home improvement store. To ensure your cut is straight you will want to use a square and mark the top of your tongue as well as the sides. This is highlighted in the linked installation instructions for the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 that you referenced.

  • Should I Use a Bolt On or a Weld on Fold Away Coupler On a Shorelander Trailer with 3x3 Frame
  • I more or less agree with you. The Fulton Fold-Away Hinge Kit for 3 x 3 inch Trailer Tongue - Weld-On, item # FHDPW330300, is a cleaner look and if you got a bad weld job you would not have a safe setup. I have done some welding, I am in no way a professional weldor, and in my limited experience a good weld will not fail before the steel it is welded to will fail. If you like the clean look of the weld on I would have a certified weldor perform the operation. If you take the trailer to...

  • How Much of the Trailer Tongue Needs to Go Inside Each End of a Fulton Trailer Tongue Hinge Kit
  • The trailer tongue will need to go in at least 3 inches on each side of Fulton Fold-Away Coupler Hinge Kit, # FHDPB330301 to retain strength and structural integrity. You may be able to have another inch of the same size tubing welded to the short end so that it gets the full 3 inches. Welding should be performed by a qualified professional welder.

  • What Angle does the Fulton Fold-Away Coupler Open Up To
  • The couplers will swing 180 degrees. Depending on how long the tongue is and the shape of the trailer the coupler may hit the trailer frame before it opens up to 180 degrees. I installed one of these on a small boat trailer this summer. The tongue was 36 inches long so we cut it at 18 inches and installed the Fulton Fold-Way. It doubled back on itself when folded out and we gained 18 inches of garage space.

The hinged coupler kits fit the 2 x 3 inch, 3 x 3 inch, 3 x 4 inch, and 3 x 5 inch tongue size. You will also want to make sure when installing the hinged coupler kit that the distance you put the hinge at on the trailer tongue will still allow you to maintain the correct weight capacity and tongue weight for your boat and trailer.

  • Recommended Fold Away Tongue for Boat Trailer
  • If you need a fold-away tongue on your boat trailer, then I recommend the Fulton Fold-Away Coupler Hinge Kit for 3" x 3" Tongue - Bolt On - Up to 5,000 lbs # FHDPB330301. This coupler hinge is corrosion-resistant with a Z-max 600 zinc finish. I recommend the Fulton Fold-Away Coupler Hinge Kit for 3" x 5" Tongue # FHDPB350101. I recommend the # FHDPB230101 for a smaller 2x3 inch tongue.

  • How to Install Weld-On Folding Trailer Coupler on Trailer Frame
  • The Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 fits only a 3 x 3-inch trailer tongue. We do have other sizes of folding coupler, all are shown on the linked page, but none fits a 2-1/2- x 2-1/2-inch trailer tongue. To use one of these on your trailer you will need to use a 3 x 3 weld-on type coupler like # FHDPW330300 and have the qualified welder who will install it also install steel spacer plates on the trailer tongue before welding the coupler into place.

  • Does the Trailer Tongue Need to be Cut at an Angle to Install a Fulton Fold-Away Coupler Hinge
  • You would want to just cut straight across when you install the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301. You could cut the coupler at the same angle as the hinge if you really wanted to, but it is not required.
