I selected the weld on application for its clean appearance. The added expense of using a certified welder for the installation was well worth it, I'm very satisfied with the product and it looks as if it was factory installed. Always a pleasure dealing with etrailer and your prompt service.


Comments
Very satisfied as it saves room in my garage, great product.

I have used two of these now on my two boat trailers. They work great! Just weld in place which is easy if you have the equipment and knowledge. Worst part is painting and redoing the wire harness. Has the added benefit of making the tongue a couple inches longer too which is a good thing for me. Makes a huge difference on storage requirements of boats on trailers!! I did use one on a 2.5" tube trailer, just cut a piece of 3" square tube 1/4" wall thickness and welded in-between. Worked great. I will use again for sure when I get a new boat!

One year ago I had a friend weld the fold away coupler onto my ShoreLand'r trailer because my boat would not fit in the garage. Now I can put the boat in a secured place and leave all of my gear in it without fear of anything walking off and the convenience of not having to move things in and out all of the time. I have pulled the boat many miles since then without any issues , thanks etrailer this has been a well worth purchase. Ken B. Wonder Lake, IL

The product worked very well for what I needed. I needed to lengthen the tongue of my trailer to get the boat deeper into the water when launching it but didn't want that to interfere with storing it in the garage. It was nice to have a chart that came along with it that gave length of tongue vs weight of boat so that you can more easily decide what length will work for your application.

I've had the folding tongue for a year now and appreciate it more every time I need to get into my limited storage space. I got the weld on unit and it was my first significant mig welder task. I had no trouble at all. It pivots smoothly into position when needed, then tucks back out of the way when I'm done. The only issue I had with it was figuring out the proper length of safety chain ) since it has to go behind the folding portion, and how best to attach the chain so it doesn't drag. A bit of trial and error solved that, though I wish this unit came with points of attachment for the chains

Before I comment on this product I'd like to thank E Trailer for their AWSOME SERVICE!!! 3 DAY FREE SHIPPING! I know I spent the required amount to get free shipping, just did not ever think E Trailer would upgrade to 3 day shipping. THANKS, for reviving my faith in retail sales!!! The swing-away casting looks great, functions perfectly. And to top it all off, E Trailer had the best price. I won't need to shop around for trailer stuff anymore. Thanks!

Fantastic product. It made my boat trailor a lot smaller to get it in storage. Heavy duty item. Easy to work with. Had it welded on(smart move). Worth every cent. Great service, fair price, very happy! Will use them again for other trailor items

This product is great! The trailer still pulls straight just like before but now i can fit it in my garage.

  • Inside Dimensions of Fulton FHDPW330300 Fold-Away Trailer Coupler Hinge
    The Fulton # FHDPW330300 fold away coupler hinge is designed to slide over a 3 x 3 inch trailer tongue, so the inside dimension is just slightly larger than 3 x 3. To install, you'd cut the trailer tongue at the point where you'd like it to fold, slide the hinge over the tube and weld it into place. The hinges aren't intended for use on aluminum trailer frames. Fulton also makes bolt on hinges for a 3 x 4 tube, part # FHDPB340301 or 3 x 5 tubes, part # FHDPB350101. I've linked to a product...

  • Fulton Fold Away Hinge Kit Recommendation for Trailer Tongue that is 2.75 by 2.75 inch
    The 3 inch by 3 inch hinge kit part # FHDPW330300 is the correct hinge you'll need, but since your trailer frame is a bit smaller than 3 inch you'll need to use spacers on the frame to take up the additional clearance so that it fits tightly.

  • Option for Extending a 3 inch by 3 inch Trailer Tongue
    The only way I can recommend a tongue extender for your trailer that has a 3 inch by 3 inch channel is to remove your current coupler, install the hinge kit part # FHDPW330300 in place of it and then install your coupler onto a length of 3 by 3 channel, and then install this into the other end of the hinge kit. This will give you an extension for the tongue of your trailer and will allow you to fold the coupler back for an additional clearance if needed. Otherwise you would need to take...

  • 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...

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.

  • Can the Fulton Fold-Away Coupler Hinge Kits Be Used To Flip Up the Tongue
    I do have an option for you but you cannot use a fold-away kit and install it so that the tongue flips up. The reason for this is that the downward pressure the trailer has would be too much force for a fold-away kit to handle while installed in the above manor. The only option you have if you need to reduce the overall length of the trailer is to use a fold-away kit and swing the tongue to the side. The Fulton Fold-Away Coupler Hinge Kit part # FHDPB230101 or part # FHDPW230300 is the...

I have attached a link to our product page for the hinges we offer. They are designed to fit specific size trailer tongues. For example, if you have a tongue that measures 3 x 3 inches then part # FHDPB330301 is the fold-away hinge kit I recommend for bolt-on or # FHDPW330300 for weld on.
