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.

Demco eZ-Latch in Use

Sturdy, Corrosion-Resistant Construction

Made of sturdy steel, this coupler features a durable zinc coating that has a 200-hour salt spray rating, which is designed to limit rust and corrosion. 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.

Received our package right when it was estimated to arrive, it work our great on my trailer

Still working great best investment I bought
Hershel - 10/01/2021


When the OEM steel brake lines wore out on my boat trailer I decided to upgrade the surge brakes to electric over hydraulic (EOH). I replaced the damaged lines and wired up a Demco actuator and now I can stop my trailer on a dime.

Although I could have continued to use the original coupler (surge) it was already quite worn and a pain to open. So into the trash it went and on went this nice new Demco 18K coupler.

Now, even my daughter can uncouple the trailer.

100 Satisfied!
Captain H - 07/26/2019


This coupler works great, it is very high quality and I love the locking mechanism. I used it in very rugged conditions (mountains and snow) and it has not given me one single issue. I have another trailer coming and I plan on changing the stock coupler out for this one as soon as it gets here. I would recommend this product to anyone.


I rarely do reviews and after 1 year, I find that I really like this hitch. The self latching onto the ball works and is easy to see that the hitch is indeed latched. The entire hitch is heavy duty, and gives me confidence to a pull a big heavy classic boat all over the western US.


New coupler works great. Had to drill one hole that did not match up with old surge coupler but that was no issue. Here is before and after pics. Will definitely come to you guys for any other trailer needs. Thanks.


We raise cattle, so we don't have the luxury of a hardware store a block away. A friend told us of etrailer. GREAT folks to work with! Ordered what we thought we needed. It didn't fit. "No problem," returned it to etrailer and they helped us get the correct DM13203-95, 2 5/16 ball, 3" channel tongue that our draw-bar required.
While talking with the folks at etrailer, they recommended the GT-1007 trailer document holders. These document holders have functioned very well, keeping the registration & license papers dry and free of mud, dirt & dust on our trailers so far - 110 degree summer heat, heavy rain / mud, gravel, snow, freezing night time temperatures and highway speeds. All are still in perfect working order.
We have recommended etrailer to others and will continue to do so.
Thank you etrailer for your knowledgeable staff, quick response time, and good pricing.

The document holders are still in super shape, & of course so is the 2-5/16 coupler.
Ron - 03/16/2019


I ordered the coupler for my jet ski trailer. I was tired of changing back and forth between ball sizes so I standardized to 2 5/16. Cut the old one off, welded shins to the tongue, then welded the coupler on. I like the auto latching feature.


Was very good service and handling of my order


heavy duty, good quality


Exactly what I needed (making all of my trailers 2-5/16")



I now have one of these hitches on both of my boat trailers so I never need to switch hitches from my work trailer hitch. The one boat trailer has had it for 2-3 years and it still works flawlessly. Very easy to use and well made.


Perfect fit replacement part for the boat trailer rusted one.


The measurements and hole placements where exactly as advertised, making a difficult custom job on an old homemade trailer a little easier. Great product - very well built, yet easy to drill additional holes when/if needed.


Heavy Duty. Kind of wished it had a metal handle, but will probably work just fine.


Used this product to replace the original on the trailer which was a 2" coupler. I wanted a 2 5/16" coupler so that all of my trailers use the same size ball. With the adjustable height hitch I use, now I only need to adjust the height rather than changing the ball as well. This is a great product, very well built. I own eleven different trailers and the latch mechanism on this coupler latches and releases better than the others I currently use. I will buy another when the need arises.


Super easy to couple my fish-house trailer with this design. Solidly built.


Bought it so my trailers would have same size ball. Very easy to use. Just unbolted the old hitch and put this one on. Very pleased!

Still working great!!
Bill - 04/14/2018


Very heavy duty and easy to use


Great quality. Exactly as described.


Great coupler. I got tired of swapping hitch balls on my truck, so I swapped this coupler onto my bass boat trailer. Now all of my trailers have the same size ball requirement. I like the easy latch system too, you don’t have to open it to latch it, just drop the coupler onto the ball and it auto latches.


I got this hitch coupler as a replacement for my boat trailer hitch. I wanted all my trailers with the same hitch size. This product worked perfectly and it has been over a year of use with no problems! I highly recommend this product!


purchased this coupler to create an extension for my sailboat trailer that with together with the boat has a combined weight of 10,000 lbs. The coupler is rated 18,000 lbs and is heavy duty construction. It is pre-drilled (1/2" holes) to easily bolt on to a 3 inch box steel frame. I shop etrailer because of the thorough product descriptions, how-to videos, competitive prices and customer service.


The product is solid and the holes lined up exactly to those on my EZloader trailer meaning no drilling just attach new bolts - took less than a half an hour
The mechanism for attaching the ball worked well - just lower it on the ball and it clicks into place - I just hope the non-metal piece that controls this function will be long lasting - but for now am very satisfied with the product.


Quality seems good. It doesn't self lock like advertised but that's no big deal. Just a bit overpriced I think. Otherwise good.


Not much for purchasing on line. But when i received my coupler i could not have been more pleased! Great quality fantastic fit smooth action. I would definitly recommend.

just like the day i got it. perfect could not be more pleased. thank you.

  • Mounting Hole Spacing from Top of Demco Channel Tongue Trailer Coupler DM13203-95
    On the Demco Channel Tongue Trailer Coupler # DM13203-95 the three top row mounting holes' centers are 1-inch from the top flat surface of the coupler. I went to our warehouse and took this measurement to confirm. This and other dimensions are shown on the linked photo.

  • Coupler Recommendation to Fit 3 inch Wide Coupler
    It's very unlikely your trailer has a channel that is 3-1/2 inches wide as that's not a common size at all. The part # 83010 that you referenced is designed to fit a 3 inch wide channel so what you would want is the # DM13203-95 which is a 18k coupler that would work well.

  • Locating VIN on Top Brand Trailer
    Typically, the trailer VIN will be located somewhere on the trailer tongue. If you cannot find one there, check for plaques on other parts of the trailer. It may also be stamped onto the trailer frame itself. You will want to move the trailer around and check the underside, especially near the axle on the primary frame members. If you cannot locate the VIN on your trailer, your local state police or highway patrol should be able to assign a VIN for you.

  • Permanently Removing Brakes from a Boat Trailer and Immobilizing the Actuator
    More than likely the reason you are having issues with your hitch sliding back and forth is that your coupler is still articulating. To stop it from articulating there are a few options. You can do so by drilling holes in either side and sliding a bolt through to prevent the coupler from compressing or you can weld the coupler to prevent it from moving. You can always remove the coupler and replace it with a coupler like the Demco Channel Tongue Trailer Coupler # DM13203-95 (this is a very...

  • 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.

  • 2-5/16 Trailer Coupler Compatible With 3 Inch Channel Tongue
    All the channel tongue couplers we offer are fits for a 3 inch channel, but I do have a solution. You could use the Demco # DM13203-95 channel tongue coupler, and shim each side of the channel tongue out using some 1/2 inch steel plate. This would be an acceptable solution.

  • Replacement Latch for Fulton 14K Straight Tongue Coupler or Replacement Coupler
    We don't have a confirmed fit for your Fulton Coupler for a repair kit.

I recommend instead for a confirmed fit replacing your coupler with the Buyers Products Straight Tongue Trailer Coupler - Auto Latch - 2-5/16" Ball - Bolt On - 15K # 3370091562 which is the closest to your 14K or the Demco Channel Tongue Trailer Coupler - Zinc - 2-5/16" Ball...

  • Coupler that's Easier to Lock than Bulldog Collar-Lok
    You are correct, all someone would need to do is cut the metal rods you pointed out to be able to slide the sleeve back of the coupler. Because of that you might be more interested in a Demco Coupler # DM13203-95 which uses a much more concealed latch and lock mechanism that wouldn't be as easy to defeat. For a pin lock for the Demco the part # e98888 would work really well too.

I recommend using the Trailer Coupler Lock # e98888 which has a 3-3/8 inch span and is 1/4 inch diameter. For further security when disconnected from your vehicle, I recommend the Coupler Lock # e98894.

  • Recommendation For Converting Drum Surge Brakes To An Electric Over Hydraulic Drum Set Up
    Since you are going to be using this on a boat trailer, I definitely recommend HydraStar. Their actuators are built of extruded anodized aluminum for corrosion resistance, have weathertight seals protect internal components, and include marine-grade gaskets and stainless steel hardware, so they are designed for use with boat trailers. With that being said, we do not have a plug and play kit available for drum brakes at the moment, but we do have a kit that includes everything you need....

This fits 3 inch wide channel, is designed to fit a 2-5/16 inch ball like you have and has an 18k capacity. For a similar weld-on coupler we have the part # DM12662-97 which comes primed for paint as well. Either would be a great solution for use with the Hydrastar part # HBA16 you are planning on installing.
