    Fold-Away Bolt-On Trailer Coupler

    Will I have issues using this steel Fold-Away couple on my aluminum trailer? Corrosion issues or anything?

    logic tells me it wont work... so anyone know a solution for folding tongue on an aluminum trailer?

    you could do a variable length tongue, the type that slides under or into the existing trailer setup. make it fully retractable and I think you;d make your space requirements.

    heres a link

    The photo image shows it to be a Fulton trailer tongue hinge.



    I have used Fulton hinge for years on my aluminum Triton double PWC trailers, first was a single axle Triton Elite double and currently a modified double axle Triton WC2-2. I have also posted photos and info on using the Fulton tongue hinge.

    I have not encountered any significant corrosion issues.

    Is your aluminum trailer a Triton? PWC trailer?

    This is the feedback I was hoping to see, someone using it and being fine! Thank you.

    I just bought a brand new seadoo and triton trailer so of course am wanting to make sure its all safe. turns out the trailer is a bit too long with the seadoo on it. This fix seems perfect!

    I think with the zinc coating on the steel coupler should be fine.

    also read this bit of information as well:
    if the base material is a large sheet of aluminum, then using very small stainless steel screws will not dramatically decrease the life. Conversely, if you use aluminum to attach a large sheet of stainless steel, the aluminum life will be dramatically shortened.

    Single PWC Triton trailer?
    Which model Triton?

    I have not looked closely at the tongue on a single PWC Triton, in terms of the wall thickness of the aluminum square tube. If it is the same thickness as the double Triton tongue then it should be just fine.

    Do pay attention to the details.

    Attach the tongue jack to the tongue/frame behind where you make the cut.

    Extract/protect the trailer wiring during the metal cutting.

    File the cut edges smooth and rounded before assembling the hinge to the trailer. I suggest sleeving the trailer wiring in convoluted plastic wire loom tubing to protect it where it goes through the hinge.

    Plan where and how you will connect the safety chains to the frame of the trailer and to the hinged tongue. Chains must bolt to the trailer structure. On my own I ran the chains inside the tongue. Bolt through the tongue and chain inside near the coupler and another bolt farther back through the tongue stub. Plastic sheath on the chain where it goes through the hinge.

    I purchased LTWCI-X. And from watching YouTube videos and the advise you have given I agree with the recommendations and will be sure to use them. The frame is 2x3 so that's the Fulton couple I ordered. I could not find wall thickness so hope it's fine. Thanks for the info!

    A friend confirmed to me that the tongue on his single Triton PWC trailer (only a few years old model) is 3x3 aluminum.

    I appreciate you finding that out for me. It makes sense as that's the much more common size. I luckily was not only able to cancel my order on the 2x3 but ended up saving money and have ordered the 3x3! It all worked out luckily . Thanks again

    So ive got a response from one of the retailers and this is what they said : "Aluminum trailer frames have a greater wall thickness than a steel frame. The bolts that attach the hinge to the trailer frame have a large diameter shoulder which acts like a rivet, holding the parts together very tightly. Since an aluminum trailer frame has a greater wall thickness, the shoulder won't have contact all the way through the metal, resulting in a looser fit."

    I just wanted to clarify that you do not have these said issues with yours?
