  • Option for Extending a 3 inch by 3 inch Trailer Tongue

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...

  • Inside Dimensions of Fulton FHDPW330300 Fold-Away Trailer Coupler Hinge

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...

  • Where Should a Fulton Fold Away hinge be Located on a Single Jet Ski Trailer
  • There are certain maximum pivots you can go up to depending on the gross trailer weight and tongue weight.

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....

Therefore, if you have one of these three frame sizes then the actuator will work for you. However, if you have either the 3" wide x 3" tall or 3" wide x 4" tall then you will also need the Titan Adapter Kit part # T4842100 (Qty. 2 for 3" wide x 3" tall and Qty. 1 for 3" wide x 4" tall).

  • Should a Folding Coupler Hinge Kit be Welded All the Way Around the Trailer Tongue

  • Replacement Surge Brake Actuator for Titan Aero 6000 for Disc Brakes
  • A Titan Aero 7500 will fit in place of your Titan Aero 6000 but the only one available for disc brakes is the Swing-Away Actuator w/ Electric Lockout # T4839100. This fits a 3" x 5" channel tongue but can fit a 3" x 4" or 3" x 3" with adapter spacers kit # T4842100 or # T4842100 accordingly. If you are looking for more of a traditional actuator then you can use either the 7.5K # 099-175-20 (with 3" distance between bolt holes) or the 8K # T4747220 (with a few different bolt holes).

  • How Much Clearance Needed Between Bed Rails and Bottom of 5th Wheel Trailer Overhang
  • We recommend that there be at least 6 inches between the bottom of the cab overhang and the top of the truck bed rails on your 6-1/2-foot bed truck. Anything less than this bare minimum could result in contact between the truck and trailer when driving on hilly roads where the nose of the trailer is still going downhill and the rear of the truck is heading uphill. My research on the PUMA indicates a pin weight of 1026 lbs and a dry weight of 6910 lbs. I cannot say exactly how much rear...

  • Replacement Actuator Recommendation to Replace Discontinued Atwood Surge Coupler
  • Atwood was bought out by Lippert recently and they basically dissolved all of their surge couplers and replacement parts as they were very problematic. Best option we have would be a surge drum actuator like the Demco part # 8605001 which is designed to work with drum brakes and fit a 2 inch ball.

  • 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.

  • Why Fulton Fold-Away Coupler Hinge Kit NOT Recommended for Aluminum Trailer Frames
  • I spoke with my contact in the Tech Services department at Fulton, who explained that 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. This is why they don't recommend...

  • 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...

  • Can Fulton Coupler Hinge Kits Fold Up Instead of to the Side
  • I might have a solution for you, but the Fulton Fold-Away Coupler Hinge Kit, # FHDPB230101, was designed to be mounted to where the tongue will fold to the side. Mounting the hinge kit to where the tongue would fold up provides no lateral stability and should not be used in this way. It sounds like your trailer frame is 3 inches wide and 2 inches tall. What you could use instead would be the 3 inch by 3 inch hinge kit part # FHDPB330301 and then use a spacer on your trailer frame so...

  • Swing-Away Tongue For Aluminum Trailer With Galvanized Steel Tongue
  • For your aluminum trailer with a galvanized steel tongue (swing-away tongues cannot be used on aluminum tongues), you'll need a die-cast steel tongue with a zinc finish from Fulton. The correct fit is going to depend on the size of your trailer tongue, as well as the thickness of the material of your current tongue, which must have a thickness between 0.188" and 0.120". If your trailer tongue's material thickness meets that requirement you can choose from the following, based on your...

  • With the Fulton Fold-Away Coupler Hinge Kit for 3" x 4" Tongue - Bolt On - Up to 7,000 lbs # FHDPB340301 installed you will get some up and down movement.

  • Could Trailer Safety Chains Attach to the Inside of a Trailer Coupler Channel
  • Running safety chains on a trailer on the inside of the channel would be pretty difficult as it would be hard to secure them to the inside of the channel and it would get a bit complicated where the chains come out since they would be right where the coupler attaches to the ball. With that being said, if you can find a qualified fabricator who could securely attach safety chains/cables to the inside of your frame channel what you are asking about would be feasible. You would just...

  • Weight Capacity of Fulton Fold-Away Coupler Hinge Part # FHDPB330301
  • I have spoken with one of our contacts at Fulton, who tell me that exceeding that 5000 lb capacity is NOT recommended. The Fold-Away kit is designed for a static weight of up to 5000 lbs, but that figure can be momentarily exceeded each time you hit a bump or a pothole. I would recommend taking your boat to a truck scale to verify the actual weight of the boat and trailer. If you find that you are under the 5000 lb figure, the Fulton Fold-Away kit would work very well for you.

  • 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.

  • Why do Safety Chains Have to be Behind Fulton Fold-Away Coupler
  • The chains need to be to the rear of the coupler of the Fulton Fold-Away Coupler Hinge Kit for 3" x 3" Tongue - Bolt On - Up to 5,000 lbs # FHDPB330301 because it is a DOT regulation, for which quality and reliability of a product has no bearing. Specifically it requires the chains to be attached to "any point to the rear of the attachment point" based on my research. I have added a link to a video review for you to check out as well of the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301.

  • Recommended Tool to Cut Trailer Tongue to Install Fulton Fold-Away Coupler Hinge Kit FHDPB330301
  • There are several different tools that could be used. A reciprocating saw is a fairly common tool that most will have access to. An angle grinder with a thin cut-off wheel would also work. If money were no object, a hand-held band saw would be ideal. Whichever tool you decide on, it is very important that the cut be perfectly straight. Use some c-clamps to clamp a straight edge onto the trailer tongue for the saw or cut-off wheel to follow. Keep in mind that the pivot length (length...

  • Weld-On Fold-Away Coupler Hinge for 3x3 Inch Trailer Tongue
  • Technically you could weld on the bolt-on hinge # FHDPB330301, but instead, just use the weld-on version, # FHDPW330300. The bolt-on one is not meant to be welded on so the warranty would be voided if not installed the way it was intended. Plus the actual weld-on one costs less. The other issue is that the bolt-on version is zinc coated so that could cause some toxic gasses to be released when welding.
