Video Transcript for Curt Straight Tongue Trailer Coupler C25094 Review

Today we're going to take a look at the Curt Straight-Tongue Posi-Lock Coupler Repair Kit for the class one coupler. This Curt replacement posi-lock latch is easy to install. Fits on the straight tongue posi-lock class one couplers that are designed to put on the 1-7/8th inch trailer ball. This part is made from a hardy steel construction. It has a nice durable zinc finish to protect it from corrosion, wear, and tear. Has a unique feature of the posi-lock latch which is its adjustable design right down here you can see.

This lockable latch mechanism will adjust by tightening or loosening this lock nut within the latch. Makes for a nice firm hold on the trailer ball. This Curt posi-lock repair latch is designed to fit a 1-7/8th inch trailer ball and it can be used on a 2 inch, 2-1/2 inch, or a 3 inch wide channel coupler. The posi-lock is your little lever right here that you can just release. That'll release it from the ball and when you push it down to close it, it will lock right into that notch right there. That should do it for the review of the Curt Straight-Tongue Posi-Lock Coupler Repair Kit for the class one coupler..

I have a 1972 Sears Luggage trailer that my son damaged the Coupler by running it over with his car. I thought the trailer was toast with no way to repair it. By chance I happen to find the Etrailer web site and low and behold they had the exact part I needed! Coupler Repair Kit for 1-7/8" Curt Channel Couplers worked perfect and the trailer is ready to go.


If I could give it 10 stars I would. The coupling mechanism on an old trailer that I recently bought went bad last week and did some serious damage to my car when it broke and the tongue of the trailer came off of my vehicle. I cut the coupling mechanism off of it and just got this one put on last night. I am absolutely thrilled with this product and with the money it saved me from not having to pay someone to cut the tongue off and weld on a new one. I could not be happier with it.

A year later this thing still works great! I probably only use my trailer once every few weeks but it has exceeded my expectations so far

I was attempting to convert my trailer from the old style "screw down" coupler to the newer clamp spring style, so ordering this part was an experiment for me. However, the new part installed quickly and easily, and worked very well! The piece is very sturdy and none of the parts seem flimsy at all. Great product!


Great product and fits like a glove and the price was right

It’s a great product
John O - 11/28/2021


The product was delivered on time as promised and was the exact quality presented. The website was easy to search and included the size of the hitch ball and not just a class or weight description. I was replacing a coupler that was damaged and needed only the repair parts. I will use this site again as needed and gladly recommend the site.

Great, reformed well and installed easily.

Received in mail around 5 pm. With hacksaw removed old and had new one on by 6 pm.


Great service!!!


I was surprised to receive my order so quickly. Sometimes it is hard to know exactly what part it is that we need. When I ran over the hitch and broke the lock, I thought the trailer was done for. But further investigation showed me that this part could be removed and from there my search began and I ended up at It was so easy to find the replacement for the lock there. Ordering was as simple as could be and installing this part was no problem with the instructions that were included. Thank you


Easy website to use and quick response on shipping


Simple install. Seems to be well made. Works just like the original coupler that I sort of ran over with the tractor. As always, good price, good product, very speedy shipping and there is always a real person that answers the phone if you have a problem. Etrailer is my go to place.


I couldn’t believe how easy this was to install. The locking mechanism on my little utility trailer over the winter. The local trailer place wanted $165 to replace it. This did the trick and is still working a year later.


As always quality product !
I always
purchase my trailer parts from Etrailer .
They have excellent customer service , quality parts below retail cost ,fast shipping and their web site is easy to navigate to find the exact part needed.


Product was good quality and instructions for install were clear and easy to follow. Worked great on repair of my boat trailer coupler. Thank you


Snow plow guy bent the old one making a pass. Ordered this and was an exact replacement. Only made one trip to the dump, so I can't say anything about its longevity, but, so far everything seems just fine.


Curt coupler repair kit is well made and installed easily.Will order again for any other trailer parts needed in the future.


Fast delivery thanks


Needed to replace a broken coupler on the trailer I pull behind my ATV. This was exactly what I needed and it fit and continues to serve well. Price was good and ordering was easy.


Installed the latch today, went without a problem. Looks much sturdier than the old rusted one that I replaced. The shipping. was fast, price was great and I am "one happy camper"!!!


After running over my trailer hitch and husband a bit mad, I found the replacement part and at great price to boot!!


The product was received and it is better than I expected. Very beefy! I also was impressed how helpful and informative the agent's (Nicole R.) ability to answer any question I had before she took my order. I did not have to ask the cost of shipping as she automatically offered my choice of snail mail or UPS by quoting the price of each. When the part was shipped she also kept me informed on it's progress. It was a pleasure to find a company that knows how to operate with such good customer concern. ==Ray==


Ordered a part for my trailer hitch. Best service I have ever had. Best price on the part will recommend and use again for anything I need.


Excellent product. Fast shipping. Best prices around. Easy lock replacement for my trailer .


Amanda was very helpful and courteous. The product we ordered was delivered within three days. Very satisfied with the service and product. Would reccomend to anyone needing trailer parts

  • What Size Hitch Ball is the Curt Coupler Repair Kit # C25094 Designed to Fit

  • Are Curt Coupler Repair Kits Different For Class ll And Class lll Trailer Hitches
    The difference between the Curt Coupler Repair Kit is the size ball the coupler is designed to work with. If you have a 1-7/8 inch hitch ball, the repair kit you need is part # C25094. for a 2-inch hitch ball you would need part # C25194.

  • What Size Locking Pin Do I Need for the Curt Coupler Repair Kit # C25094?
    For the Curt Coupler Repair Kit for 1-7/8" Curt Channel Couplers # C25094, you need a pin no larger than 3/8". For this measurement, I recommend the Bulldog Easy Access Coupler Lock - Swivel Head - Chrome # BD580409. I attached a picture with the measurement of the pin hole.

  • Is a Coupler Repair Kit Available for a Shelby 5133 Coupler?
    Shelby was acquired by Dutton-Lainson and we no longer carry Shelby coupler repair kits. I recommend instead getting a new coupler such as # CT-3001-Z. I've left a link to a video review of this coupler as well as a link to our page with each of our 2" ball couplers for you to take a look at.

  • Trailer Coupler Replacement for Shelby 5138
    The Shelby coupler you have now is a standard trigger-latch style of coupler that fits a 3 inch frame channel which we have great replacements for. For a high quality replacement I would recommend the Demco coupler part # DM15000-52 which has a very easy to use latch system that also is very reliable and won't get hard to use over time like most do. This also fits a 2 inch hitch ball. Check out the review video I attached for more info on this coupler as well.

  • 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.

  • Can a Trailer Coupler on a Vintage Trailer be Repaired without Knowing the Coupler Manufacturer
    I would need to know the model and/or manufacturer of the coupler. The issue is that the repair kits are not universal so I cannot guarantee that what we have will fit. The one thing that will work is to replace the coupler. Since you mentioned that the trailer is an A-frame but the channel is 2 inches wide I assume that the coupler is mounted to a single pole at the front of the A-frame. For a straight tongue coupler that fits a 2 inch tongue and couples to a 1-7/8 inch ball we have #...

  • Coupler Lock That Fits 1-7/8" Shelby Coupler
    There is a coupler lock available for your 1-7/8" Shelby coupler, though they locks themselves aren't truly "universal;" oftentimes they say they will fit "most" but will name specific brands and types they fit. For example, the Master Lock Universal Trailer Coupler Lock # 379DAT will fit a 1-7/8" straight lip, rolled lip and surge brake/hydraulic couplers from Shelby, but also from Reese, Fulton, Valley, Atwood, Shelby, Putnam, Bulldog, Dutton-Lainson and UFP. There is also the Blaylock...
