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.

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.

Awesome coupler, works so well that I converted my other two trailers over.


I had to enlarge the mounting holes to fit my trailer which had 5/8" bolts.


I love the new type of trailer coupler so I bought this one to convert our 2" ball trailer to match our other trailers. The Bolt holes lined up and everything. Very happy with the conversion!


Fast shipping.


Great customer service. My parts arrived in a few days after I ordered.
Thank you.


Exactly what I ordered. this was a direct replacement of the one that was previously on my trailer


Thank You for the fast service


Clean, simple design. Big improvement over my old style coupler.


Great coupler . I wouldn’t use any othe rbrand.


Exactly what I expected, good service, good product.


the demco coupler is exactley what I need to refit my trailer delivery a day ahead of schedule shipped the day ordered the team did a great job Recommend any need of parts to Etrailer will be back for more


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.


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.


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.


Exactly what I expected. Very nice looking product.


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 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.


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.


Nice communication with customer service! They gave me options and updates on my back-ordered item.


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.


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


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.


Quick shipping good prices


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.


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.

  • 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.

  • Demco Coupler that Fits 2-5/16 inch Hitch Ball and 3 inch Frame Channel
    Demco has a similar coupler for 3 inch wide channel that fits the 2-5/16 inch hitch balls with the part # DM13203-52 but the part # DM12925 that you referenced only fits the 2 inch hitch balls. The # DM13203-52 has an easier to use latch mechanism as well. Nothing in the ball size you want from Demco has the trigger latch like the coupler you mentioned.

  • Is There a Trailer Coupler Repair Kit for Trailer with 2-5/16" Coupler
    I know this is not what you want to hear but the vast majority of trailer couplers cannot be repaired, they will instead need to be replaced. There are very few trailer coupler repair kits available and they are by no means universal. Therefore, unless you have the exact coupler said repair kit is designed for (highly unlikely), it's not going to work and the coupler needs to be replaced. For this, we do have a great option for you though that won't require any welding making it capable...

  • 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.

  • Demco Channel Tongue Coupler Compatibility with 3 Inch Wide Channel Tongue
    The Demco Channel Tongue Trailer Coupler # DM13203-52 is made to fit a steel tongue that is 3 inches wide and can be 3 inches, 4 inches, or 5 inches tall.

  • Parts Needed To Convert 2014 VM Boat Trailer With Surge Disc Brakes To Electric Over Hydraulic
    Yes, the Hydrastar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes # HS481-8067 would be the correct kit to use on your boat trailer with surge disc brakes. Depending on what type of channel and coupler you have will decide on the best coupler. Most boat trailers will use a 3" wide coupler so you might find either the 2" Ball # DM15000-52 or 2-5/16" Ball # DM13203-52 to be your best option. If you can measure your trailer tongue and send me an image of your current coupler...

  • Is There a 2-5/16" Coupler That Can Be Used in Place Of a Shelby 5135 2" Ball Coupler?
    Instead of replacing your Shelby 5135 with the Coupler # CT-5003-Z which has the same design and 2" ball coupler you can replace it with the Demco 2-5/16" # DM13203-52. Both couplers fit a 3" wide trailer tongue. This coupler will require you to drill different mounting holes in your frame as they are not an exact match.

  • 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...

  • Switching from Surge Brake Actuator to Electric Over Hydraulic on Shorelandr Boat Trailer
    In order to convert from a surge brake actuator to an electric over hydraulic actuator you'd need the actuator itself, a breakaway system, and wiring. I recommend the Hydrastar Marine Electric Over Hydraulic Actuator Kit part # HS381-9067 which comes with all these items in a nice and convenient kit. In regards to switching out the surge brake actuator, you have many options for this but it will depend on your tongue style, the most common is a straight tongue and in which case I recommend...

  • 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...
