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 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 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 - DM14040-52 Review

Today we're going to be taking a look at part number DM14040-52. This is the Demco channel bracket trailer coupler. It's designed for 2 and 5/16 inch hitch balls. This coupler is made of a study steel construction, has a really nice silver powder coat finished on it to resist rust and corrosion and it's got the easy latch mechanism that's going to ensure fast, easy, secure hookup and disconnect. The adjustable channel bracket and mounting hardware are sold separately. Now this coupler is going to let you hook up your trailer to your tow vehicle. It's going to provide the connection point for your hitch ball and it has the easy latch coupler mechanism with the corrosion proof composite latch handle.

It's going to ensure simple, secure hookup, and disconnect. It's very strong and very durable and the contour is really nice around the front of the coupler giving it a nice sleek, clean look. Now the easy latch design is going to let you hook up when the latch is in a close position. You can do that with the latch open as well but the beauty of this system is that you can do it with the latch closed. All you have to do is drop the coupler over the hitch ball and the latch will automatically snap into place engaging the hitch ball. Disengaging is just as easy.

All you got to do is look up on the lever and it's going to automatically release its grip on the ball. The neat about an adjustable channel mounting design is it's going to let you change the coupler's height depending on your application. These holes are going to have a diameter of 5-8/7 inch and it's going to have a hole separation measuring from the center of one hole to the center of the other. Looks to be right at 2 inches. Again sturdy steel construction. This is going to feature a 500-hour salt spray rating so it's going to be great for marine applications. Ball size is 2 and 5-16 of an inch.

It's going to offer 21,000 pounds when it comes to weight capacity. Taken measurement back here outside edge to outside edge, it's going to measure just under 3 inches so it's going to allow this coupler to slide into a 3-inch wired channel bracket. Again sold separately, you can find those here on the website. Overall length from very front to very back, that's going to give us a measurement, looks to be about 8 and 1/8 of an inch. Last thing I want to point out is here on each side at the front of the coupler you're going to notice a small hole. On the top of the easy latch design, it says that the 5/16 inch hole.

It's on the side of the coupler and it's designed for theft determent only. What that means is you can actually install a coupler pen and lock and that's going to make sure that nobody comes and hooks up to your unattended trailer. You can also install a coupler pen and lock when this is connected to your hitch ball or to your application. That's going to ensure safety. It's going to make sure that nobody comes up and removes the trailer from your set up and connects it to theirs. Again the diameter of that hole is going to measure 5/16 of an inch and in the span measuring from outside edge to outside edge, it's going to measure about 3 inches. That's going to do it for our review of part number DM14040-52. This is the Demco channel bracket trailer coupler for 2 and 5/16 inch hitch balls. .

Replacing a sloppy 21K pintle with this hitch, pintle came with a trailer I bought used so this will be a quiet replacement to pair with my B&W Tri-ball I bought a couple years ago with etrailer.

Great quality coupler, easy hookup and release.

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


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


My order shipped quickly and showed up in good time. The coupler looks good, but i was disappointed in the gross tongue weight of 10% of total Gross trailer weight. This was not advertised in the details online. I was expecting a 20% tongue weight. If there is another coupler with a 4k/21k rating id appreciate a link.


Comments
I checked and we do not have an adjustable coupler that has a higher TW capacity.

Review from a similar eZ Latch Coupler in Adjustable 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.

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!

Best coupler I've ever used! Very impressed and will be swapping out on another trailer that also has a finicky coupler latch.

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


Comments
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


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.

  • Bolt Hole Size Spacing, and Channel Metal Thickness for Demco 21K Trailer Coupler
    First, the thickness of the metal channel that the Demco trailer coupler # DM14040-52 is going to bolt onto will be 1/4 inch to 3/8 of an inch thick. Or you could split the difference and say 5/16 inches. As far as the size channel, it is designed for a 3 inch wide channel such as # DM59602 which would be welded to the trailer. The holes are spaced 2 inches apart on center. The bolt holes are slightly larger than 5/8 inch diameter for use with 5/8 inch bolts, # PS024202.

  • Replacement Inner Slide and Coupler for a Demco DA91 Surge Actuator
    The Replacement Inner Slide for Demco DA91 Actuators # DM12808-97 replaces the inner slide for your Demco DA91 brake actuator and would allow you to use the Demco Trailer Coupler # DM14976-52 for a 2" coupler or the Demco Trailer Coupler # DM14040-52 for a 2-5/16" coupler. The Slide Repair Kit for Demco Hydraulic Brake Actuators # DM5942 is the correct slide for your DA-91 if you are needing that.

  • Recommended Trailer Coupler w/ Adjustable Channel w/ Lunette Ring and 2-5/16 Coupler
    I have a couple of options for you depending on what the front of your trailer's coupler looks like. If you are needing an entire adapter with a jack hole then I recommend the Trailer Tongue Vertical Channel Weld-On Adaptor with 6 Bolt Holes - Welded item # SHK95RR. This has a 3" channel with six adjustment holes. You can then use the 2-5/16" Demco Trailer Coupler item # DM14040-52 and the Buyers Products Plain 10-Ton Forged Steel Lunette Ring w/ 3" I.D. item # 337B16140. If you just...
