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 zinc coating that is designed to limit rust and corrosion. This finish has a 300-hour salt spray rating, allowing it to stand up to the elements.

Video Transcript for Demco Adjustable Trailer Coupler - Coupler Only - DM15791-95 Review

Speaker 1: Today we're taking a look at a Demco Trailer Coupler.This cast ball coupler lets you hook up your trailer to your tow vehicle. It simply provides a connection point for your hitch ball. It is designed to work with a 2-5/16" hitch ball, and the unit has a weight capacity of 21,000 pounds.Now, this unit features the eZ-Latch mechanism. This ensures simple, secure hook up and disconnect. The eZ-Latch design basically lets you hook up with the latch in the closed position. All you have to do with the eZ-Latch design is drop the coupler over the hitch ball, and then the latch will snap into place, engaging the hitch ball.

Now, when you want to release, or disconnect, then you still have to lift up on the handle right here, but again, the eZ-Latch design is when you're connecting. All you got to do is drop this over your hitch ball, engages automatically without having to lift up or disengage the actual lever and trigger right here.It's designed to fit into a channel bracket, so the adjustable channel mount design lets you change the coupler's height, depending on your application. Channel bracket and mounting hardware are sold separately, and available at etrailer.com if needed.We're looking at a sturdy steel construction, with zinc finishing, which offers corrosion resistance. It does have a 300 hour salt spray rating, and it's SAE J684 certified.Now, this is designed to fit inside of a 3" wide channel bracket. We can tell that by taking a measurement edge to edge right here.

The mount holes on the unit are separated on center by 2", and the overall length of the unit, measuring front to back, gives us a measurement of about 8-1/8".Also on this unit, you have two pin holes, so you can either install your standard coupler pin, or if you want to upgrade it, add more security when you're connected, and when you're disconnected, you could actually upgrade to a coupler lock. So, you have a pin hole right here, and a pin hole right here. This one basically keeps the wedge from being operable, so that would be great for your unattended trailer, as well as your connected trailer. Then this one right here would keep the handle from being able to operate, which again would be great for your connected trailer or your unattended trailer.The diameter of those pin holes is 5/16". The span or usable pin length needed for this one up here is going to be about 1-1/8.

The usable span or pin length for this one down here is going to be around 3".Now, please note, four 5/8" Grade 5 mounting bolts must be used to achieve the 21,000 pound weight capacity.That's going to do it for today's look at the Demco Trailer Coupler.

Hitch works great, almost no chance of user error, very positive coupling with min. play on the ball. Zinc plate is thick and uniform. No chance to damage the paw it's very robust.
I did have to drill the lock pin holes with 8mm bit because a 5/16" hasp on the lock was to tight.

The coupler that came with our teardrop did the job, but getting hooked up and secure on the ball was a real pain that would take multiple attempts to reposition it before it dropped fully in place. I like the Demco eZ-latch. So much better. I uploaded 3 photos: 1) original coupler, 2) trailer frame with new holes drilled and old holes filled with Bondo, 3) Demco coupler in place. The changeover was very easy.



by:

Very good quality, construction, and finish. This was used to replace a 5000# rated coupler on my RV trailer that was just not strong enough. It has an extra 2-3" of length than the old coupler so make sure your safety chains have enough length to accommodate the extra length. One bonus for me was that the extra length was just enough to allow me to open the back door of my SUV with the trailer hitched (which I couldn't do before). The DEMCO coupler does take a 2 1/2" wide hitch pin /lock which is different than most couplers.



by:

I’m a 75 year old disabled woman who was about to give up traveling due to the efforts to hitch and unhitch my trailer. I got this new hitch installed and it changed my life; it is effortless. I’m on the beach now while a winter storm is raging around the U.S. thank you so much for a hitch that changed my life.



by:

Heavy duty for sure. Drilling 1/2” holes in 1/4” thick angle iron on the trailer required more than a hand drill, but other than that installation was simple. Removing the original coupler was a chore because it was welded on both top and bottom. I had to use a hacksaw (3 blades), 2 lb mallet, large crowbar, steel chisel, grinder. Fortunately I had all that, and I’m very pleased with the result.



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:

It's held up well after a year of abuse. We've fitted all our trailers with these couplers for uniformity, and haven't had any troubles.



by:

I decided I wanted to renew my Dad's old trailer. Starting with a trailer coupler upgrade to the adjustable "eZ-Latch". Thanks to etrailer it was an easy, convenient one stop shop and I couldn't be more pleased with the products and service. When it comes time to do the running gear and tires, etrailer will be my source.

Thank you!



by:

Exactly what I needed to replace the sloppy pintle hitch on my trailer I’m rebuilding.



by:

Excellent coupler, very heavy duty, easy hook up and unhook, definitely recommend if you need a trailer coupler.



by:

When my old coupler failed I was very happy to find a bolt on coupler this heavy as most are weld on for a trailer this heavy. I wish I would have changed the coupler years ago. I always had trouble with the old one. This one is so easy to latch and unlatch from my truck. It is great quality.



by:

Very nice hitch release lever. Easy to grab and lift to release. Easy to install.



by:

I have been using this on my 15,400# trailer since purchased no issues.Easily locks and unlocks .



by:

We're switching all of our couplers to the Demco eZ-latch. They've been very reliable and easy to use.



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.



by:

love these couplers ! they are the best and are easy to open up and when they are pulled up you know it is disconnected !! the best !

I was a little disappointed when I opened the box yesterday and found that there was no keeper pin with the couplers now I have to go to town and find the right size ! I was thinking it would come with one ! should have a option to buy the correct one or just send one with !! thanks

  • Replacement for Dico Model 5 Brake Actuator for 1980 V/M Boat Trailer With 4 Inch Channel Tongue
    Unfortunately, we don't offer a surge coupler to designed to slip over a 4 inch trailer tongue. I tried doing a Google search for a Dico model 5 to locate a recommended replacement, and got zero results and didn't get any results for 4 inch wide surge coupler either. I believe your best choice would be a weld on application like # DM8759922 which would weld to the top of the trailer tongue. You'll want to use a professional welder to do this for you. You'll also need a coupler like #...
