eZ-Latch Coupler

This coupler features a simple-to-use latching mechanism known as the eZ-Latch. With this mechanism, hooking up is as easy as dropping the coupler over your trailer hitch ball. The latch does not need to be tugged or manually activated to allow the ball into the coupler socket, nor does it have to be secured in place. Just make sure that the coupler is properly lined up with the ball when you lower it, and the rest is automatic. Disengaging the coupler is just as effortless. Simply lift up the contoured handle and the coupler socket will automatically release its grip on the ball.

Sturdy, Corrosion-Resistant Construction

Made of sturdy steel, this straight-tongue coupler features a durable silver powder coat finish that is designed to limit rust and corrosion. This coat has a 500-hour salt spray rating, making the coupler perfect for marine use. The eZ-Latch's sleek, ergonomically designed handle is constructed of a durable composite material that's corrosion-proof, allowing it to withstand whatever the road and the elements dish out.

It looks good . The only issue I had was the bolt hole didn't quite match. I had to drill them out.

On this coupler it is 3 inches on center from the hole closest to the coupler to the middle hole. Two inches on center from the hole furthest from the coupler to the middle hole. And 1 and 7 eighths inch on center from the closest hole diagonally to the lower hole.

I like it but some times it is a bit difficult to get the lock disengage


Fits and works well


Used the 2 5/16" coupler to replace a 2 inch one on our trailer that a debris vacuum is mounted on. It works fine, with no issues. It allows us to tow the debris vac behind our trucks that have a ball/pintle hitch combination. Glad etrailer had the size, as could not find it locally. Thanks.


I have several trailers of various sizes. I pull a trailer for work nearly every day, so I've experienced poor quality hitches and great quality hitches. It fit perfectly and is definitely made of high-quality craftsmanship and materials. It functions as advertised.


I was converting all of my trailers to 2 5/16" ball, so I didn't have to have different size ball inserts laying around and not being able to find the size I needed. I also like the feature that locks on the ball without unlatching the lever.


This is a very sturdy built trailer coupler. The quick attach makes hooking up a breeze. I purchased it mainly to have all of my trailers running the same size ball hitch. I would recommend this trailer coupler to anyone.


Have 2 now one boat trailer and now one on trailer I build this winter so all 3 of my trailer are 2-5/16in now. No more forgetting to change balls all the same, I like the couplers very much.


I ordered this hitch because all my farm work trailers have a 2-5/16" hitch and my boat had a 2". So I found this hitch on and removed the 2" hitch for this one and now all are the same, saving me a lot of trouble and time. When you are 60 years old and have back problems, changing the hitch when you want to go boating is the last thing you want to do.


We were unable to get a product like this locally, and this type Trailer Coupler will work perfectly for our job. The people at did a fantastic job of keeping us informed about our order. We're very happy with


I am very happy with this product. It went on the boat trailer. It was easy to install. The quality was above others we looked at for more money. We will recommend you to others.

Thank you for checking on us. The coupler is great. No problems. Looks and works well.

Nice product. Excellent quality. My first purchase on etrailer was easy to complete with outstanding selection of product to choose from. Packaging could have been better because edge of coupler was extending out through cardboard box when arrived.


Just received this hitch in the mail , going to put it on later today , it came quick and is very solid

Love this hitch it has held up very well !! Would buy again
Brent - 04/15/2018


The best review one could write would be that they would buy this product again from the same supplier:. I have made purchases from ETRAILER before and if I ever needed another coupler this is the one I would buy. Extremely easy to mount and operate.


Hands down, this is the smoothest-operating, best designed online shopping experience I have ever had.. this is no fake review, either. I ordered my stuff and it was on my doorstep the following afternoon. Perfect. Thank you!


super heavy duty, looks to be excellent quality. super fast delivery, ordered Sun. on door step Tues. and free shipping!


Really love the new release on these. This is a heavy duty tongue coupler. Very well made and looks to be strong.


Nice coupler. Just what was needed


as advertised. delivery quick. Fitted as stated and was assembled in 20 minutes, including redrill of trailer tube.


Product is high quality, solid steel. Great addition to our boat trailer.


Nice coupler. However is advertised as using 5/8" hardware and the holes are actually 1/2".


Good product but takes to long to get it in to the shipping process. Your turn around time is very slow.


Stock was back ordered. While I waited company reached out with a similar product in stock in case I needed solution sooner. I chose original product but was appreciative of the extra attention to customer needs. Product eventually shipped on the projected date. Product was packed very well and arrived undamaged.
Communication from this company is personal, professional and clear. Special thanks to Carol and the team. I will order again when the need arises.


received package very quickly was pleasantly surprised


This receiver is hardy! Solid! Ease of operation and robust. Glad I went with this choice.

  • Mounting Bolt Pattern for Demco Channel Tongue Coupler
    I reached out to Demco to get the bolt hole spacing on the Demco Channel Tongue Trailer Coupler # DM13203-52. The bolt holes measure 3/4 in from the top of of the coupler to the center of the hole. This is the same measurement for the distance from the bottom of the coupler to the center of the lower bolt hole. I have attached a photo showing these measurements. For this coupler there is not an adjustment for the tension on the hitch ball. I confirmed this with my contact at Demco. The...

  • What is Difference Between Demco Couplers # DM13203-95 # DM13203-52
    The difference is the finish of the two couplers. The Demco coupler part # DM13203-95 is a galvanized metal finish which is basically a zinc coating and the # DM13203-52 on the other hand is a silver powdercoat finish which is basically like a really durable paint.

  • Does the Demco Channel Tongue Trailer Coupler Come with Installation Bolts
    The Demco Channel Tongue Trailer Coupler # DM13203-52 does not come with the bolts required for installation but they can be sourced from your local hardware store or you can use the Pro Series # PS024202. If you do source them locally, the holes are 5/8" diameter and you'll want to use Grade 5 bolts for this application.

  • Coupler Lock for Demco Channel Tongue Trailer Coupler # DM13203-52
    You can use the Coupler Lock # e98894 if you are looking to keep your trailer from being coupled to. If you are looking for a lock that prevents it from being uncoupled then that would be the part # e98888. Either of these are great options to help secure your trailer with the Demco Channel Tongue Trailer Coupler # DM13203-52 and deter theft.

  • Lock Recommendations for Demco DM13203-52 eZ Latch Trailer Coupler
    I have a couple of options that would work for you. If the trailer is sitting around not coupled to anything, and you're wanting to prevent an unauthorized person from coupling it and driving off, use # e98894. If you're wanting to prevent the trailer from being uncoupled from a hitch, use # e98888. This lock will also prevent the trailer from being coupled, but I find the # e98894 to be more secure. The # e98888 would be inserted through the transverse hole just below the latch, as shown...

  • What Coupler Lock do you Recommend for my Demco 2-5/16 EZ-Latch Coupler
    For your Demco Channel Tongue Trailer Coupler part # DM13203-52 I recommend using the etrailer Surge Brake Coupler Lock part # e98888. This is designed to place through the coupler pin hole just under the latch and keep it from being able to operate. This will prevent it from opening or closing eliminating any issues. If you want complete coupler coverage the etrailer Trailer Coupler Lock for Flat Lip 2-5/16" Ball Coupler part # e98895 is an excellent choice. They are both very easy...
