I couldn't find a 1-7/8" coupler with a 3" channel anywhere locally; so, I decided to order one from etrailer. I'm very pleased with the product. It fits like a glove and works great. I was also impressed with etrailer's fast shipping. I will definitely order from them again.

Nice product. Sturdier then previous coupler I removed. Easy to use safety latch. Easy to install. Arrived quickly. Thanks!

Great product! Still like it well. You all sell good stuff.

What impressed me that this part fit exactly on my trailer that is over 40 years old. It showed up on time and it was the same price it would have cost locally--if they had it--which they didn't. Pictured--old new.

I am in the process of replacing the tongue on my lightweight utility trailer and decided to install a new hitch at the same time. etrailer provided the best selection including various quality upgrades for the particular hitch style I needed. In addition, the prices were also very competitive, if not the best. My purchase arrived exactly on time and in excellent shape. I'll be returning to etrailer fro my other trailering needs.

Fit fine. Works fine.

It was easy to install and it fit my 1 7/8 ball on my 2000 Camry so I could tow my 16' Bayliner Bowrider.

It still works well after a year. Use aluminum or copper thread compound on the bolt threads so you can remove it in the future.

I purchased from the website here because they provided a great description of the coupler and I knew it would line up with the holes in my trailer tongue. Too many other sites did not provide enough information but etrailer.com had all the specs I needed to make an informed decision.

I ordered this coupler because it is made in U.S.A. The coupler is a little more expensive than the china made options available. This coupler is much better quality than the china made coupler it is replacing for me. Very happy!

Here's the new one installed. Absolutely perfect. Thank you.

Hard to find 3" bolt pattern in 1-7/8" ball coupler... found it at etrailer with help of customer service... good price, fast shipping and made in USA.


Comments
No complaints...Two things I LOVE about it: First, it had the bolt pattern I needed without modification and second, it has a heavier construction than the others I looked at that I would have had to modify. Im very pleased with this purchase!

Good piece and fit perfectly on my small craftsman lawn tractor trailer. The coupler slid right into the channel and I used the existing hole on top to bolt it into place.

Just what I ordered also came in on time as paid for, thanks for the excellent service.

Product was exactly as described. With some slight modifications to the tongue on my Brinly dump trailer, I now have a trailer I can hook to my X300 John Deere lawn tractor using a 1 7/8 trailer hitch ball. Love it. No more getting down on the ground to insert a hitch pin and cotter pin.

Very satisfied with this trailer coupler. It replaced my old rusty one perfectly, and I'm impressed with the quality. Very easy to install.

The product worked perfectly. E-trailer shipped it right away and delivered exactly what was promised.

by:

Nice coupler, easy install. Quick shipping from etrailer. The only reason I'm giving it 4 starts instead of 5, is it didn't come with new bolts. Not really an issue, just assumed they would be included. Overall, pleased with product.



- DL13728
by:

Shiny! But seriously, it fit and worked perfectly. I was so happy to get rid of that old, rusty, beat up thing that was on there. I did learn how to adjust the coupler to fit the ball properly. Very happy with it.



- DL13728
by:

I received my trailer coupler in a timely manner with no damage to the product, now I just have to figure out how I am going to mount it for the tongue of my pull behind trailer is pretty close to the same size of the channel of the coupler.

Your website was easy to use, prices were fair and delivery was timely.

This product was a direct replacement for my boat trailer. Installation was a breeze and the finish looks great.

I got this to replace the old one on my motorcycle trailer that had gotten hard to operate. The old one must have been the same unit as the new one fit perfectly.

Ask the Experts about this Dutton-Lainson Straight Tongue Trailer Coupler

  • Is There a Straight Tongue Trailer Coupler With Built-In Handle for Easy Maneuvering
    I have just what you need. The Trailer Coupler 1-7/8" Ball 3" Channel Tongue part # DL13728 which you could add the Trailer Coupler Grip Handle by Dutton-Lainson part # DL13350 to in order to help maneuver the trailer. I am not aware of any one piece coupler/handle combo but the above will work perfectly for you.

  • What is the Distance Between Bolt Holes on 1-7/8
    From center to center, the distance between the two side bolt holes on # CT-2003-Z is 2-1/4". On # DL13728 the distance is 3". Both trailer couplers fit a 3" channel tongue, a 1-7/8" ball and are rated at 2,000 lbs. If you are replacing your coupler, it may also be time to replace your coupler lock. I recommend the etrailer.com Coupler Lock, # e98893, which works with 1-7/8" couplers.

  • Size and Type of Bolts to Install Trailer Coupler DL13728, 1-7/8 Inch Ball, 3 Inch Channel Tongue
    I spoke with my contact at Dutton-Lainson, the manufacturer, about the hardware requirements for Coupler # DL13728. She told me that to mount the coupler, you will need two, 1/2 inch bolts, that are 3-1/2 to 3-3/4 inches long. With this type of hardware installed, the coupler will be installed properly, according to manufacturer recommendations.

    Why not just use the repair kit part # DL13968 to replace the internal components of your Dutton Lainson Coupler 940-1 so that you wouldn't have to mess with cutting or replacing components. This would be the easiest solution to the problem you have.

  • Does Trailer Coupler Need to Sit Flat Against the Top of Trailer Tongue
    Ideally, you want the coupler sitting flat in direct contact with the top of the trailer tongue. If the gap between the bottom inside of the coupler and the trailer tongue is pretty minimal, say 1/16 of an inch or less, having it the way it is would most likely not cause a problem, but I would recommend you go ahead and fix it. This can be done in two ways. You can remove the coupler, cut about 1 to 1-1/2 inches off the end of the trailer tongue so you have fresh steel to work with and...

  • Straight Tongue Coupler for 3 inch Channel for 2 inch Hitch Ball
    You certainly can go to a coupler that uses a 2 inch ball like you mentioned. For that we have the Dutton Lainson # DL13897 which fits the 3 inch channel you have as well.

  • 2k Rated Trailer Coupler Recommendation for 3 inch Wide Frame Channel
    We have several 3 inch channel trailer couplers that could work for you (see link). For a 2,000 lb capacity coupler the Dutton Lainson part # DL13728 is a very popular option that would work well. I would have a qualified weldor, weld a Safety Chain Loop, # E950, to the bottom of the trailer frame and then attach safety chains, like part # 2118-348-04, with Safety Chain Quick Links, # 2114-553-04.

  • Can Dutton Lainson Coupler DL13728 Fit on Trailer Tongue that is 75 mm Wide
    Your tongue has a width of 75 mm or 2.95 inches which is very close to the standard tongue width couplers are designed for of 3 inches. That would be close enough for the Trailer Coupler # DL13728 that you referenced to tighten onto and work well. Basically I'd mock up the coupler installed on your tongue where you want it and then drill holes using the coupler as a template.

  • 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.

    The Coupler Repair Kit for 2" Curt Couplers # C25194 might fit your Dutton Clausen coupler, however I can't confirm that it will or will not fit.
