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

great add on feature to my utility trailer! by adding this fold away coupler to my existing 4X8 trailer tongue and a 40" additional tube, my trailer is more versatile for my uses, with the longer tongue it is easier to back up without Jackknifing, I can add canoe racks and carry 18' canoes nicely balanced over the axle and no worry of hitting the back of the vehicle. when trailer is not in use folding the tongue back out of the way is nice for garage storage or driveway space. my trailer is rated at 2200# capacity, and by the charts provided by Fulton, the tongue length I added matches the rating of the coupler. installation directions were good, hardware is good quality. 861946

The Fulton Fold-away Coupler Hinge was extremely easy to install with great instructions. The hinge is strong and tight. The pin slides in and out with very little effort making the hinge easy to fold or place back in the tow position. I am very happy with the purchase and it reduced the storage length of my boat and trailer by almost 2 ft. 805260

The tongue hinge arrived yesterday. Today it went on much easier than I anticipated. Follow the instructions and you will find it easy to install. This is a great product that I strongly recommend to anyone who has a storage issue of a boat/trailer combo or any other trailered item. 791688

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

Ask the Experts about this Fulton Folding Trailer Tongue

  • 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...

  • Could the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 be Used to Extend a Trailer Coupler
    The Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 that you referenced is designed to be installed on a 3 inch by 3 inch trailer tongue to allow it to be folded away. If you wanted to make an extension for your trailer you would need to find a section of 3 inch by 3 inch pipe, remove your trailer's current coupler, install the # FHDPB330301 in place of it, and then attach the coupler to the section of 3 inch by 3 inch square pipe you bought, and then install the piece with the coupler...

  • Differences Between the Fulton Coupler Hinge Kits FHDPB330301 and FHDPB330303
    The difference between the two Fulton Swing Away kits you referenced is the material that is used for each of the kits. Other than that they are the same and are designed to fit 3 inch by 3 inch trailer tongues. The # FHDPB330301 is made of stainless steel which will resist corrosion and the part # FHDPW330300 is made of a raw steel which will corrode much easier. You could paint either kit if you like. I attached a picture a customer sent to us that shows his painted white to match...

  • 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...

  • Fulton Fold Away Hinge Kit 3x3 Fit on Trailer Tongue that is 7-3/4 inches Long
    You would need to install the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301 on the smaller 3 inch by 3 inch section of the tongue on the coupler. It would fit on your trailer that has a length there of 7-3/4 inches and would work well. It would add a bit of length to the tongue when folded out, but it still would fit and work just fine.

  • 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....

  • 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 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.

  • 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 the Fulton Fold-Away Coupler Hinge Kit Be Used Behind Winch/Bow Stop of Trailer
    As long as the length of where you install the # FHDPB330301 is compatible with the weight of your boat and trailer it can be installed anywhere on the tongue as needed. Having the winch and the bow stop be between the hinge and coupler could make it difficult to fold the hinge when the boat is loaded on the trailer, but if you determine that it wouldn't interfere or know that you won't use the hinge when the trailer is loaded you would be fine.

  • Does the Trailer Tongue have to be Cut at an Angle to a Install Fulton Fold-Away Coupler Hinge Kit
    When installing the Fulton Fold-Away Coupler Hinge Kit, # FHDPB330301, you will just cut the tongue straight across. You can cut it at an angle if you really wanted to but it is not required. because of subtle tolerances it would be best to use the hinge kit as a template to get the best angle so you would want to wait until you have it to do so. Make sure to get the right pivot length for your trailer tongue weight and gross trailer weight. I have included a picture that should help.

  • 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.

  • Troubleshooting Up and Down Play with Fulton Swing Away Hinge Kit on a Magic Tilt Boat Trailer
    Thanks for sending pictures! The titanium shims you installed are just fine, but note that the inch of play is absolutely normal per my contact at Cequent Corporation. The Fulton Fold-Away coupler hinge kit you referenced is most likely very similar to # FHDPB330301. Your aluminum trailer is not intended to work with the coupler hinge kit because it's steel. Drilling holes on your aluminum Magic Tilt boat trailer is a safety concern and over time it will break.

    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.

  • 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 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.

  • 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.

  • 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.

  • 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.
