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. .

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


Better made than the original load rite piece. Much better hitch mechanism. Very pleased with it. Purchased for a 2year old single axel Load Rite UT-510. Load Rite confirmed this is the correct replacement piece. It is not. Bolt holes did not match up.. Had to drill new ones into the frame. Very pleased w Demco. Load Rite? Not so much love going there.


Comments
I am not sure about this being a direct replacement for anything but we do have the specs listed in the description for people making a switch in brands.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


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.

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


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!

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


this was an effective solution to a bent trailer coupler and twisted frame. i did add welds and a piece of channel to the frame before i bolted it down. 4 stars because i had to hunt around for a lock long enough to go thru the hole in the front. definitely recommend if you have a difficult repair on a trailer coupler.

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


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.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


I purchased the premium version of this bolt on coupler. I replaced a cracked welded original, and likes the bolt on feature. Used grade 8 bolts, its not going anywhere. It is extremely beefy, thick and heavy steel. The finish is excellent. It has a 500 hr salt rating. I clamped it into place with C clamps and used the holes in the coupler as templates to drill into the channel steel on the trailer. As a result, a perfect fit. It fits the 50 degree angle of the trailer channels like a glove. The fastening mechanism works very nicely. Unlike other fastener systems, it simply engages or disengages a spring that sets the locking mechanism. It requires that you pull the trailer forward under tension slightly to lock it in place. It has a beefed 5/16” locking pin hole. I purchased my locking pin locally as e-trailer has a 5/16 pin but it is not long enough as specified for this. A pin is not supplied, I don’t think this is normally supplied anyways.


Comments
Good, continues to work well. It requires placement against the ball or it does not close, typical of most hitches. It seems to snap right in place I like it. Worried the lever is made of plastic.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


Wow. This is what a trailer hitch should be. Up to now, I tended to buy trailer couplers based on low price, provided it was rated high enough for what I was pulling. This time, I decided to spend a few extra $$$ to get a premium coupler, and I wasn't disappointed. Coupling and un-coupling is the easiest I have ever experienced, fit and finish are excellent, and it looks built to last a lifetime. After years of struggling with a trailer coupler that was difficult to latch and unlatch, this is a breeze (you had to have things lined up exactly, and then still look/reach underneath to be sure the little 'catch' had grabbed the ball, plus fight against a spring-loaded lever to latch). With this coupler, you just park so the ball is under the coupler, and lower the trailer. As you lower the trailer, the little release lever will start to rise up off the coupler. When it 'snaps' back down, you are locked in place. Couldn't be easier. To unlock, just flip the lever up, and raise the trailer. No fighting a little latch that requires you to be exactly centered before it will latch, no way the latch can miss holding the ball in place, and no fighting the catch to un couple. I wish I would have known about this style of coupler years ago. It costs a few dollars more (but not much for one of equal tow ratings) but it works better than any other coupler I have used. Well worth it, if you hook and unhook your trailer with any frequency at all.


Comments
Still the best coupler I have. I have used it extensively, even doing some pulling with a tractor, and the coupler never fails to connect easily, and securely, and unlatches easily. If it seems reluctant to unlatch, just pull ahead a little to relieve pressure on the lock.

Review from a similar eZ Latch Coupler in Adjustable Trailer Coupler


I have built several trailers in the past and I am currently building a tilt bed car trailer. I have made several purchases from etrailer.com They are great people to deal with and all of the products that I have purchased have met or exceeded my expectations. For this build I am using dropped axles which make the trailer tongue 5 inches lower than one with straight axles. I needed to be able to raise the coupler to prevent using a drastically dropped draw bar on the tow 4WD tow truck. I chose the Demco channel mount adjustable coupler to allow for the needed adjustment for different tow vehicles. This is a very well built coupler that attaches to the channel with 4 high strength bolts, not 2 like most other mounts. It also features auto latch system so you just lower the trailer onto your ball and the Demc automatically locks on the ball. Great product.


Comments
Demco coupler does a great job. Automatic hookup is very nice no problems

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.

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.
