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 A-frame coupler features a durable silver powder coat finish that is designed to limit rust and corrosion. This finish 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.

A-frame coupler is made of sturdy steel and has a silver powder coat finish, making it ideal for marine applications. eZ-Latch ensures fast, easy, secure hookup and disconnect. Includes cutout for your 2-1/4" round jack. Bolt-on installation.


I had to grind the coupler off of our 1970 Airstream to install this unit. Took 1/2 day to grind off the coupler and smooth off the welds. I ended up using three 3/8" drill bits to drill the 10 holes required for the Demco coupler. It also required that I elongate the jack stand holes as the top and bottom shelf holes where not exactly lined up perpendicular so the jack sat at a slight angle. I only had to elongate both holes about 1/8". I used a sabre saw with a very good blade and cut a very neat edge. It was a 2 day job doing it in my driveway at my pace and wasn't really difficult. It did require perseverance but the end result is worth it. Nice coupler and it feels secure.


Was looking for a stainless coupler for my aluminum car hauler. Never could find one, so I tried this powder coated one from Demco. It has worked very well. Pleased with how it has held up being stored outside. Still looks like the day I installed it. Awesome product!


Like that you can put the latch down before coupling to hitch.


Beefy! Excellently what I was looking for! Fit was spot-on; lined up perfectly with original coupler. EZ-Latch works as advertised. Outstanding service from etrailer


You guys were great in processing my order and shipping it out to me in a timely to my fault I chose the wrong one..its to heavy for my jeep. I need to order the coupler but with 2 inch ball hitch.I'm going to call tomorrow to order another one


I purchased this coupler to replace the coupler on my 1997 Featherlite trailer. The coating and the five hole pattern (to match the existing coupler) were my determining factors. I also REALLY wanted to get a coupler with the EZ-Latch setup as I had heard nothing but good things about that type of ball latch system.

This coupler worked perfectly for me! I had it bolted on in a matter of minutes and the EZ-Latch system is the only way to go!!


Its is bending up where the tongue jack is mounted so I'm really not that happy with it week metal i guess


I am very pleased with the online catalog of etrailer, the description of the trailer coupler was very accurate. It is well built and made of heavy steel. I have it installed it and it allows the trailer to follow my truck very true. I was a little apprehensive about the auto connect feature. After a couple of times of hooking the trailer to my truck, I don't think I would change. I purchased the bolt on style for future ease of changing out the coupler if it is ever needed. The only draw back is that all the holes and bolt threads are metric not ASE. I will definitely come back to etrailer in the future.


Great quality however the delivery took about a month due to it was on back order.


It’s been a year and I’m having to replace the hitch on my trailer once again. The factory one broke around the ball. This one is cracking beside one of the factory welds. I do put a lot of miles on and the trailer is around 18k loaded. So all in all it’s done it’s job.


Is has worked out great


Product is great, but it would have been nice to have some info with it, like size of bolts required, etc.

Thank you for your review. Here is an expert answer that will help you:

  • Package Contents of Demco A-Frame Trailer Coupler with Jack Center Hole # DM16680-52
    The Demco coupler # DM16680-52 you were looking at does not include the hardware needed for installation. It would be a good idea to switch over from your weld on to a bolt on coupler, this will make it a whole lot easier to replace over time as it wears out as you have stated.

  • Will Demco A-Frame Trailer Coupler DM16680-52 Fit 2015 Featherlite 3116 Trailer
    I checked the Featherlite Trailer website for specs on the model 3116 trailer but this part number returned no results. But if your trailer uses an industry-standard 50-degree a-frame design then the Demco A-Frame Trailer Coupler # DM16680-52 will fit as a bolt-on replacement. I linked a photo of this coupler to show you the mounting hole spacing.

  • Best Replacement H&H A-Frame Car Hauler 2-5/16" Trailer Coupler
    looking at all the options we have for 2-5/16 inch A-Frame Couplers, the one you're looking at # DM16680-52 seems to look the most similar. I don't see any coupler that will be a perfect replacement. The holes on our coupler seem smaller and not in a straight line like your H&H Car Hauler. I'm just on their website checking out a couple pictures. If you're looking for a direct replacement, I would contact H&H for the exact replacement. Ours will fit, but drilling may be required.

  • Trailer Coupler Repair Kit for Coleman Bayside Popup Camper
    I do have an option for you but the most realistic solution would be to replace the entire coupler which I know is not ideal since they are welded-on. That said, coupler repair kits are not universal and although I don't know which exact coupler you have on your trailer, it's very likely to be discontinued which means the odds of there being a trailer coupler repair kit compatible are very low. They do not offer trailer coupler repair kits for all trailer couplers, even the newer couplers....

    The Demco 50-Degree A-Frame Trailer Coupler part # DM16680-52 will fit any trailer with a standard 50 degree a-frame which is almost all a-frame trailers on the market today.

You'll simply need to mount the coupler, use the holes as a template to drill your own, and then you can continue bolting on as normal.

  • How Much Wiggle Room Should There Be In A Trailer Coupler
    Correct, there will need to be a small amount of wiggle room or play between the trailer coupler and hitch ball which is to allow the trailer to track and turn smoothly. If the connection point between the trailer coupler and hitch ball was too tight then the trailer would not track or turn correctly. However, if the connection point is too lose then the coupler could become detached from the hitch ball. The vast majority of trailer couplers are not adjustable but there might be a few out...

    I do have an option for you but trailer coupler repair kits are model specific and since Atwood has went out of business there are no more trailer coupler repair kits for their couplers.

  • Can Weld-On A-Frame Trailer Coupler be Replaced with a Bolt-On Coupler
    Yes, you can replace your weld-on coupler with a bolt-on. You'll just need to drill the holes. Then, if you wanted to go back to a weld-on later that would be fine too. Just to confirm you can check with the trailer's manufacturer that drilling the holes won't lower the trailer's capacity. Our most popular A-frame couplers are the Demco eZ-Latch. The eZ-Latch makes it easier to hookup and disconnect from your trailer. For a coupler that fits a 2 inch ball use # DM14793-52 and for...

  • A-Frame Trailer Coupler for a 2-5/16 Inch Ball that Can be Locked
    Coupler repair kits are not always universal. In fact it is less likely that one designed for a certain coupler will fit a different coupler. Without knowing the brand and model coupler you have I cannot guarantee that any of the repair kits will work. I recommend replacing the coupler with a new one such as # DM16680-52. It is a bolt-on A-frame coupler that takes a 2-5/16 inch ball. You can look it with a latch lock, # e98888.

  • What Causes A-Frame Coupler to Pop Off Hitch Ball
    The best option for your trailer is a new trailer coupler as either the latch mechanism is worn or faulty. I strongly recommend against any sort of jerry-rigging here as there is too much at stake for you and the safety of those around you. This means you will likely need to cut off the old coupler and weld or bolt-on a new one, the Demco 50-Degree A-Frame Trailer Coupler part # DM16680-52 is what I recommend.

I recommend the Buyers Products 3/8" x 35" Class 4 Trailer Safety Chain # 337BSC3835. You will need 2 of these as they are sold individually. The chain comes with a large clevis hook for your hitch and is zinc coated to resist corrosion.
