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 handle and the coupler socket will automatically release its grip on the ball.


Demco eZ-Latch in Use

Unlike most couplers, which only have a pin hole on the handle latch, the eZ-Latch coupler features a hole on the latch and on the side of the coupler itself. Inserting a coupler lock through this hole will keep the latch from lifting, preventing disconnect and theft.


Sturdy, Corrosion-Resistant Construction

Made of sturdy steel, this coupler features a durable black 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.

Video Transcript for Review of Demco Adjustable Trailer Coupler - Coupler Only - DM15791-81

Hello, everybody. Steve here with etrailer.com. Today we're looking together at our Demco Trailer Coupler. It's a cast coupler with an adjustable channel mount EZ Latch assembly. Now folks, this is made for a 2 5/16 inch hitch ball. It's rated at 21,000 pounds capacity, and as you can see, all that is stamped onto the side of it as well.

Now, it does provide the connection point for the hitch ball and the EZ Latch mechanism here ensures simple secure hookup and disconnects. I actually pulled a ball for demonstration purposes, so I've got a 2 5/16 inch ball here. And with the EZ Latch coupler, all you simply have to do is drop it onto the ball and it automatically does its thing. Now we are hooked. And then to unlatch it, simply lift it up and it would come right off the top of the ball.

So again, on, off. So, really simple to use. I really like these EZ Latch mechanisms and it's adjustable channel mount, so it's gonna fit a 3 inch channel mount there on the back. And it is 8 1/8 inches long overall by 2 7/8 inches wide. And again, it fits a 2 5/16 inch ball and that 3 inch wide channel bracket, which is just your standard width on those.

It can withstand a 500 hour salt spray rating for marine grade applications. it's SAE J684 certified, and it's a very sturdy steel cast construction. Again, black powder coat finish as you can see, and that's gonna provide excellent corrosion resistance. Now, as far as mounting it to your channel, all that hardware is sold separately. If you don't already have it, you can get that here at etrailer.com along with the channel as well.

Well, folks, that's gonna wrap it up. I'm Steven, thanks for your time. As always, stay safe while you're towing.

The hitch is excellent for our 14,000lb equipment trailer.
Only issue is the hole for the padlock was too small for any locks and we drilled it out to accommodate one.
Con- Shipping was not very good. It was returned to the dealer twice because it was sent via United Postal Service and our shop has not Post office box. Only a location address. The USPS does not take packages to our location. We could not seem to get the package sent via UPS or FedEx to us.
Only time this has happened when ordering from etrailer.



by:

The ease of latching and not having to lift the latch handle is very nice and unlachine it's a breeze, works very well very happy with the coupler



by:

Great product! This thing's built like a tank. We're always pulling the heaviest things possible with our trailers and this stands up to the job.



by:

Was very easy to install. I did have to grind a bit off the back so I could get clearance for the bolt holes to line up. Only took about 30 min to install.

It is great. Way better than the factory original.

Coupler works great, used daily.



by:

Great info and rapid service



by:

The coupler would come loose unless it was pinned before I loaded my tractor on the trailer. This coupler stays open when hooking up and closed when in use.

VERY WELL BUILT HITCH.

This hitch works great, easy on and latches automatically. When unhooking the hitch doesnt get hooked on the ball.

I ordered an easy latch trailer coupler in silver, about two days later I got a call and was told that silver was out of stock, but I could get sent black. I agreeed to black instead of silver. However when I received my trailer coupler it was a whole different model. I did not have time to send it back, however not the greatest to receive something different than what I ordered.

  • Difference Between Demco 15791-81 and 15791-52
    What you noticed is correct. The only difference between these two couplers is the color. The # DM15791-52 is silver and the # DM15791-81 is black. Even with a different color finish they both offer the same 500-hour salt spray rating.

  • Is The Composite Or Steel Demco EZ Latch Coupler A Better Choice Over The Other?
    Personally I prefer the Demco Trailer Coupler # DM14976-52 with the composite handle over the Coupler # DM15791-81 with a metal handle. I feel it is easier to operate as it does not have the safety latch like you get on the metal handle. Since most trailers are always outside the safety latch tends to get some corrosion in the handle and can become difficult to open. Both these couplers will need the Hardware Kit # DM6166 to mount to a 3" channel. You will need a locking pin like the...

  • How to Mount an Adjustable Trailer Coupler
    Adjustable trailer couplers are not going to mount to your truck; they will attach to the frame of your trailer. Some of the adjustable couplers, such as the Bulldog Cast Head # BDA2563C0317 come with the mounting hardware to weld onto the frame of your trailer. Others, such as the Demco # DM15791-81, come with the channel bracket # DM66134 and mounting hardware # DM6166 separately. I've added a link to our page with each of our 2-5/16" adjustable trailer couplers for you to take a look at.

  • Material of Latch Handle on Demco Trailer Coupler
    The review on the product page for the Demco Trailer Coupler # DM15791-81 is actually from a similar product and not the exact same coupler. I'm not sure the product the customer is referring to but the latch handle of # DM15791-81 is metal.

  • Availability Of A Sleeve-Lock Coupler Rated For 16K Or Higher
    I do have a potential solution for you, but we do not have a sleeve-lock style coupler rated for 16K or higher. If you are in need of a channel mount coupler for a 2-5/16" ball, we have the # DM15791-81. This will fit in a 3" wide channel bracket, and is rated for 21K
