Video Transcript for Fulton Straight Tongue Trailer Coupler - Standard Coupler - F343000301 Review

Speaker 1: Today we're going to take a look at the Fulton Straight Tongue Coupler for a two-inch hitch ball. It has a 5,000 pound weight capacity. Now, this is perfect for your towing needs. It's a rust-resistant coupler. It's designed to be bolted onto your trailer's tongue. Has a nice Z-mac 600 finish to offer corrosion resistance.

It is a durable steel construction. Has the very easy to use trigger-style latch, makes for a quick and easy trailer hookup. You just pull the trigger, release it, and it opens the latch, you're ready to go. I happen to pull a two-inch hitch ball, just to show you. With it open, you can drop it right onto the hitch ball and then just rotate your handle back down, and it locks onto the hitch ball and you're ready to tow.

To release it, again, just pull the trigger, lift it up, and it releases from the hitch ball.Now, this coupler is a bolt-on installation. You notice the holes on the side is used to bolt it onto your trailer tongue. Again, it's designed to fit a two-inch diameter ball size. Capacity is 5,000 pounds. Mounting, it's designed to fit on a three-inch wide channel tongue.A few measurements on this.

The overall length from this edge to this edge is going to right at 11 inches, overall length. The channel length, which is the inside here that will fit onto the tongue is right at five inches. The overall height of this from the very bottom to the very top is going to be right at three inches tall. And the total width outside edge to outside edge is three and three-eighths inches, inside to inside is three and one-sixteenth. The whole measurements, when you bolt it on, they are standard center-to-center, three inches.But that should do it for the review on the Fulton Straight Tongue Coupler for two-inch hitch ball, with a 5,000 pound weight capacity..

I have a Shoreline boat trailer from the early 90's that needed a new coupler. The coupler I was replacing had mounting holes drilled 1" to center from the top of the outside of the unit. Most couplers place this hole at 1 1/4" from the top which would leave the coupler sitting with a gap between the top of the square beam and the coupler. If your trailer has this less common hole placement, this coupler is a great looking and functioning unit. 121555

Th hitch installed without any problems. The only issue with the hitch is you have to have the ball positioned exacting right or the locking tongue will get jammed and the ball will not seat. It might take a few tries before you get it positioned correctly. 614202

I purchased a fin keel sailboat on a Trail Rite trailer in Oklahoma and upon getting the rig back to Colorado, I had to replace the surge brake receiver as it was completely rusted out. I purchased this receiver to replace the defective hydraulic version as well as purchasing a complete electrical brake system (drums, shoes, wheels, wiring and tires) to complete the changeover. Everything from etrailer has worked as intended. 471083

I upgraded my old rusted 3,500 lb. coupler to this 5,000 lb. one for a great price. Best part of the bargain was that shipping was only $7.99. eTrailer personnel even called as soon as I had placed the online order to tell me that they were waiting for restock of the part; that I could substitute for another brand or wait a week for my original request. Great prices and customer service! 79811

Review from a similar Fulton Fas-Lok in Straight Tongue Trailer Coupler


6 wks. ago I started on a refurbishing project off a 1988 Holsclaw boat trailer. I stripped all the paint off, ground and sanded the rust, primed and painted everything, replaced ALL the fasteners with stainless stell and some galvanized. I ordered several things from etrailer.com . Everything I ordered was to exact specifications and the shipping was on-time, everytime. I ordered several bearing items to repack the hubs, this coupler and nifty lifting handle, transom tie down brackets, spare tire carrier and 3 new 570x80 tires mounted on galvanized rims and the company installed stems, free of charge! I love the way this project came out and I've thoroughly enjoyed shopping @ etrailer.com! Thank you! 637416

Do you have a question about this Straight Tongue Trailer Coupler?


  • Comparison Between Fulton 5K And 6K Fast-Lok Coupler
  • The difference between the Fulton Fas-Lok Coupler with a 5,000 lb capacity, part # F343000301 and the 6,000 lb weight capacity coupler part # F346000301 is just that. The weight capacity. Both are a bolt-on installation, designed for 3 inch channel trailers, have trigger latches, and work with a 2 inch ball. The mounting holes are spaced 3 inches apart and both have the Z-Max 600 finish that helps resist corrosion. While the F346000301 coupler is rated at a higher capacity, it sounds...

  • Bolt Hole Dimensions Fulton Fas-Lok Coupler # F343000301
  • The Mounting Holes of the Fulton FasLok Coupler # F343000301 are 1/2 inches in diameter. The center hole to inside top of the coupler is 3/4 of an inch. The two mounting holes on the side are 3 inches apart measured center to center. I have edited a photo for you showing the measurements.

  • Trailer Coupler Repair Part Recommendations
  • In order to find the right coupler or latch for your trailer you will need to know the size of your trailer tongue or the model of the coupler needing the parts. If you have a Fulton 308 Series coupler on your trailer, then the Fulton Repair kit, part # F520801, will work for you. I have attached a link to the product page that lists the coupler repair kits and parts you can take a look at. If you are looking to replace the entire coupler, the size of the trailer channel and the ball...

  • Warranty Coverage for Dutton-Lainson # DL13897 Trailer Coupler
  • According to my contact at Dutton-Lainson, they do not cover their couplers with a warranty. However, Fulton offers an identical Fas-Lok Coupler, part # F343000301 that's covered by a 3 year limited warranty.

  • Thank you for including a photo of your WWII-vintage trailer coupler that fits a 3 x 4-inch trailer tongue. For this exact tongue size we offer only fold-away couplers such as # FHDPB340301 but we do have straight tongue couplers that will fit a 3-inch wide channel tongue and take a 2-inch ball such as # F343000301 rated for 5K and the others that you can view on the included link.

  • Can Welded-On Dico Coupler be Replaced with a Bolt-On Type
  • It is certainly possible to replace a welded-on coupler with a bolt-on type so long as the new coupler's capacity is correct for the trailer and it fits the trailer tongue. If you know the trailer manufacturer it is never a bad idea to check with them about doing that retro-fit, just to ensure that they have no concerns about drilling through the tongue for installation of the bolt on coupler. They may also be able to offer you guidance about the bolt grade to use, typically a Grade 5 U.S. I...

  • Folding Tongue Coupler Parts To Create Complete Assembly
  • The kit you mentioned has been discontinued, however, I can help you with the individual components. To make this kit, you will want the Fulton Fold-Away Coupler Hinge Kit for 3" x 3" Tongue - Bolt On - Up to 5,000 lbs # FHDPB330301. This will mount to a 3 inch by 3 inch square tube in whatever length you decide which will need to be obtained locally. On the end of that square tube is the Fulton Fas-Lok Coupler, 2" Ball, 3" Channel - 5,000 lbs # F343000301. For the safety chains, you...

  • Bolt Recommendation for Fulton Fas-Lock Coupler Installation
  • You would want to use 2, 1/2 inch diameter bolts that are 4 inches in length. I pulled a Fulton Fas-Lok Coupler # F343000301 and checked the installation instructions to confirm the bolt recommendations.
    view full answer...

  • Can Welded On Broken Trailer Coupler be Replaced
  • We don't have generic coupler repair kits that I can recommend, but most likely your coupler can be replaced if you take it to a qualified welder in your area. They should have no problem removing the coupler and installing a new one. If your hitch ball is 2 inches the part # F343000301 would work for you. This mounts to a 3 inch channel. If you have a 1-7/8 inch ball you would want the part # T4845000.

  • When Installing New Coupler on Trailer Can There Be Gap Above Trailer Frame
  • If you wanted to shim the space you have between the top of your trailer coupler and the bottom of the coupler # F343000301, you could, but if you have the bolts torqued down and you aren't overloading the coupler's 5k capacity you should be fine.

  • Does the Titan Coupler Part T4845000 have the 50 Millimeter Engraved on the Coupler
  • Yes, the Titan coupler # T4845000 will have the 50mm engraved on the topside. It also fits 1-7/8 and 2-inch hitch balls. I went to our warehouse to take a picture for you too. Other brands that have a weight capacity of 3,500 pounds and work with a 50 mm ball (1.96 inches) is the Fulton Fas-Lok # F223000301 and Dutton-Lainson channel tongue # DL13800.

  • Tongue Weight Rating on Fulton Trailer Coupler # F343000301
  • Yes, the tongue weight capacity will usually be 10 per cent of the couplers maximum weight capacity. On the Fulton Trailer Coupler, part # F343000301, that you have referenced, with the maximum weight capacity being 5,000 lbs the tongue weight capacity will be 500 lbs. Normally, when choosing a trailer coupler the gross trailer weight of the trailer is used because the couplers capacity must be equal to or greater than the gross trailer weight.

  • Recommended Fulton Fold-Away Coupler Hinge Kit Assembly
  • The complete Fulton Kit referenced in your question is no longer available from the manufacturer. I recommend looking at the Fulton Fold-Away Coupler Hinge Kit # FHDPB330301. This is designed for 3 inch x 3 inch trailer tongues and has up to a 5,000 pound capacity. This kit includes the mounting hardware, pivot bolts and the pivot pin and clip.

  • What Size Trailer Frame Does Fas-Lok Couplar # F343000301 Fit
  • Basically what that 3 inches is telling you is the width of trailer frame the Fas-Lok Coupler, part # F343000301, fits onto. It doesn't need to be a 3 inch by 3 inch frame but it does need to be 3 inches wide. The channel is the inside of the Fas-Lok that fits over the trailer like is shown in the picture.

  • Replacement 5,000 lb Fulton Coupler on 2003 Coleman Westlake

  • Coupler Lock Recommendation for Fulton Fas-Lok Style of Coupler
  • Sounds like you have coupler similar to the Fulton Fas-Lok part # F343000301 that you referenced and are looking for a coupler lock for it. A very popular option that will fit and work well is the Fastway coupler lock part # DT25013KA. We've found that this lock fits basically all styles of couplers well including the Fas-Lok and does an excellent job deterring theft.
