eZ-Latch Coupler

Cast Coupler Cutaway

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

The contoured, low-profile design of the latch handle helps protect the coupler from damage by allowing any potential hazards - from debris on the road to your ball mount backing into the coupler - to simply slide over the top. This helps prevent anything from getting under the latch handle and releasing the ball, and it can also limit any damage to the coupler should an impact occur


Unlike most couplers, which have a pin hole on the handle latch, the eZ-Latch coupler features a hole 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 red powder coat primed paint 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 an impact-resistant polymer-nylon-resin compound that provides the flexibility and strength needed to bounce back from a collision. The handle is corrosion-proof, allowing it to withstand whatever the road and the elements dish out.

Video Transcript for Demco Adjustable Trailer Coupler - Coupler Only - DM14040-97 Review

Today we're going to be taking a look at part number DM14040-97. This is the Demco Trailer Coupler. It's going to have the adjustable channel mount design. It is designed for 2-5/16" hitch balls. The cast ball coupler is made of a sturdy steel construction. It's primed.

Keep in mind that the adjustable channel bracket and mounting hardware are sold separately. This coupler is going to let you hook up your trailer to your towed vehicle, providing a good connection point for your hitch ball. It's going to feature an eZ-Latch mechanism with a corrosion proof composite latch handle. It's going to ensure simple, secure hook up and disconnect. It's got a nice contour directly right here over the coupler, right above the socket portion. That's nice, sleek, stylish design. The great thing about the eZ-Latch design is it's going to let you hook up when the latch is in a closed position.

You can see the mechanism under here. As soon as we drop this over our hitch ball that's going to open up and it's going to allow it to automatically connect. To disengage all you got to do is lift up on the large handle there. It's going to release that large mechanism which is going to release the grip on the hitch ball automatically. The adjustable channel mount is going to let you change the coupler's height depending on your application. Channel bracket and mounting hardware are sold separately.

Again, we have the heavy duty, steel construction with a prime finish. This is designed for 3" wide channel brackets. If we take a measurement from outside edge to outside edge, that's going to measure about 2-7/8". It's going to fit perfectly inside a 3" wide channel bracket. The 3" width on the channel bracket is inside edge to inside edge.

This portion slides right in, you line up your mounting holes and install your hardware. The mounting holes on the coupler are going to be separated center on center by right on 2". Again, this is designed for hitch balls that have a diameter of 2-5/16". Weight capacity on this coupler is 21,000 pounds. Go ahead and take a measurement of the overall length measuring from the very front to the very back. That looks like it's going to give us a measurement of about 8-1/4". The last thing I want to point out is right here, above the socket, looking on each side you're going to notice a small pin hole. This is going to be designed to install a coupler pin and lock system. That's going to keep the mechanisms from being able to move. You can attach a coupler pin and lock to an unattended trailer. That's going to keep anybody from being able to come up and connect and run off with your trailer. You can also install the coupler pin and lock when you have it connected to your towed vehicle. That's going to make sure that nobody comes up and removes it from your tow vehicle and runs off with your trailer. It's all about theft prevention. The coupler pin and lock is going to be sold separately. The diameter of that hole is going to measure 5/16". The span you're going to need for a coupler pin is going to be about 3". That's going to do it for our review of part number DM14040-97. This is the Demco trailer coupler for 2-5/16" hitch balls. .

Absolutely Great coupler! I have 3 trailer's with 3 different hitches. These Demco unit's are so simple and so easy to operate. I just bought a new equipment trailer last week and I struggled to get that coupler on (so did the dealer) so I ordered 2 of these to make my life easy. I now have 1 for a spare or parts if needed. Highly recommend one if you have any issue's with your current coupler. YES, they are worth it..... I'd give these more than 5 stars if I could.

they did not include a lock pin. Curt always does. it would have been 5 stars if it had a lock pin. that's going to be hard to find in my area.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


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.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


I don’t really want to write a review, hope someone will really read this.the main reason I ordered a bolt on coupling is so I would not have to weld, but I’m gonna have to even add 2in.to my trailer to make all the holes match. I would have returned it but your return policy says I would have to pay shipping ugg!!. I’m already in for 140.00 bucks now I have to pay and end up with nothing but lost of money for nothing. I’m 74 years old and did not want to weld , that was my only reason for ordering your coupling .the thing had some scratches and marks on it like it had already been a return, don’t think it was done during shipping, although it was put in a fairly large box with flimsy paper packing, so I’m going to have to make it work,even have to weld and everything. Now I’m having to waste time writing all of this , and it’s not going to even make any difference anyway. I think y’all owe me some kind of discount for all my troubles I was trying to avoid anyway, but I’m sure that is not going to happen either. GOD BLESS THOMAS OLIVER

You mentioned that you needed to add 2 inches to your trailer to install the trailer and I wanted to see if you could explain in more detail what you mean. Would you be able to send pictures?

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


Very solid hitch. Fast shipping. Fits well except your trailer channels need to nearly come to a point for the first set of holes to have anything to bolt to. Mine did not, so I am having it welded on as well. No paperwork or hardware with this package, but the video will answer most all questions.


Comments
Excellent - it’s stronger than the trailer. Weak point is the plastic lever. If I’m unhitching on an incline it won’t release. I would break it.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


This is the best hitch on the market! I've changed over all 4 of my trailers to this hitch. Simple hook/unhook, releases off the ball smooth, no pins to mess with. The included steel bracket (product #DM6125-81) is super heavy duty & so is the hitch itself, plenty heavy for any 2 5/16" trailer. I hacked off my existing hitches w a cutoff saw, welded a plate then the bracket and did each of my trailers , w paint, in less than an hour.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


I like the 4 bolt system rather than the 2 bolt system because it "mates" the two metal surfaces together better than 2 long bolt design. The way in which its tightened is better. Plus if you have 1 of 4 bolts break you can still safety tow it. If 1 of 2 bolts break you're flirting with disaster. 21k coupler on a 10k trailer. Heavier and better design than my original Made in China coupler.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


Installed this AWESOME hitch on my 20 ft equipment trailer after I upgraded to 8k axles. This hitch is a beast. I love the no touch when hooking up. Just lower the trailer down and it makes a positive lock sound. I welded the hitch to a 1/2 inch thick plate. Welded the plate onto the trailer and used my own gussets instead of the supplied ones. You won’t go wrong with this hitch!

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


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!

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


My old coupler was pretty used up and rated at only 5000 lbs for a 10,000 lb trailer so it had to go. The new bolt-on 10,000 lb coupler is quality. I like the EZ latch because its smooth, self latching and easy. The job was about four hours including removing old coupler, welding some new channel in and drilling holes. New coupler looks good, works great, and trailer is safer.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


Trailer coupler was easy to install, fits over tow ball and locks with ease. I’ve ordered other trailer parts from E Trailer and they always have shipped quickly and parts have always been what’s specified on their website. And their videos are very helpful when ordering parts. I highly recommend ordering parts from this company.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


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.
