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 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.


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 - DM14040-81 Review

Today we're going to be taking a look at part number DM14040-81. This is the Democo Trailer Coupler, it's going to be an adjustable channel mount, and it's going to accommodate your 2-5/16 inch hitch ball. Now the cast ball coupler is made of sturdy steel, it's going to feature a durable black powder coat finish for corrosion and rust resistance. It's going to feature the eZ-Latch design. It's going to ensure fast, easy, secure hookup and disconnect. Just keep in mind that your adjustable channel bracket and mounting hardware are sold separately, but you can find those right here at etrailer.com. The cast ball coupler is going to let you hook up your trailer to your tow vehicle.

It's going to provide your connection point for your hitch ball. It's got the eZ-Latch mechanism. It's got that nice corrosion-proof composite latch handle, so it's going to ensure simple, secure hookup and disconnect. Very strong and durable and it has a nice contour for a sleek design. Now, the eZ-Latch mechanism is going to let you hook up when your latch is in a closed position.

Very simple to do, all you have to do is drop a coupler over the hitch ball and the latch is going to automatically snap into place engaging your hitch ball. Now, you can connect with it in the open position, but the beauty of this system is how easy it is to operate. It's got the nice wide composite handle and that you can just drop your coupler over your hitch ball with the handle in a closed position and it's still going to connect and engage the hitch ball fully. Disengaging the coupler is really easy, all you got to do is lift up on that handle and then the coupler socket is going to automatically release its grip on the hitch ball. The adjustable channel mount is going to let you change the coupler's height depending on your application. That's great to have.

Again, heavy-duty steel construction, black powder coat finish. Take a measurement here of the width that we have, outside edge to outside edge, looks like it's going to measure about 2-7/8 of an inch so that lets us know that this is designed perfectly for a 3 inch wide channel bracket. Again, it is designed for a 2-5/16 inch hitch ball. If we take a measurement from the front to the back, we are going to get a measurement of about 8-1/8 of an inch, that's the overall length of this unit. It's going to offer a weight capacity of 21,000 pounds. Now, these mounting holes back here, these are going to have a diameter of 5/8 of an inch and they're going to be separated center on center by 2 inches.

Those are the holes that you're going to use to mount it to your channel bracket. Last thing I want to mention is here at the front, we're going to have a small hole on each side that's going to have a diameter of 5/16 of an inch. That slot is designed for a coupler pin and lock. A coupler pin and lock, once installed, is going to keep the handle from being able to come up, so if you have a coupler pin and lock installed on an unattended trailer, nobody's going to be able to go up to it and hook up and run off with your trailer. If you have a coupler pin and lock hooked up with your towing set up when it's already connected to your hitch ball, it's going to prevent anybody from being able to come up and release your trailer from your set up and move it to there. Another neat thing about a coupler pin and lock system is it's just going to work as a backup. It's going to ensure that the coupler does not disengage the hitch ball. The pin goes through there. It's going to be sold separately. You can find some options here on our website, but once that pin is through there, it actually prevents the mechanism from being able to fully open up, so that's going to keep it from connecting to or releasing from a hitch ball. That's going to do it for our review of part number DM14040-81. This is the Demco Trailer Coupler for adjustable channel mounts and 2-5/16 inch hitch balls. .

Excellent design, the only small issue is that the top of the coupler that fits over the ball is already rusting. 526058

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. 463489

Review from a similar Demco eZ Latch 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! 592298

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


Coupler mechanism is finicky, you have to shake the trailer tongue to get it to lock. The pin hole is too small in diameter to accept a lock so you have to use a ball lock to lock the trailer. Also it’s plastic so if it sticks you have to be careful tapping on it. I wouldn’t by again and if it breaks I’ll go back to normal coupler. 489782


Comments
The coupler mechanism is adjustable. Use the adjustment bolt on the underside of the latching mechanism to adjust until the coupler will self-latch when set atop the trailer ball.

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


The coupler is a fantastic, well built and easy to use unit. The installation was super simple. The coupler lock is a great piece as well, it fits great into the ball socket on the coupler and locks super tight. Great pieces of equipment. The coupler latch pin however did not fit the latch on the Demco coupler. Had to pick up a different one from Farm as Fleet, but we can use the other one on my other trailer. 126978

Looks good, quality controle could be a little better. Nothing that will effect the function. It looks like it was not cleaned after welding. There is a lot of weld splatter. I am painting it a different color anyway so I will clean it up. 527512

Review from a similar Demco eZ Latch 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. 703091

Trailer coupling will not fit correctly on a 2" Ball...to tight and is always difficult to get on and off. 440928


Comments
We have contacted the manufacturer and they suggest pulling forward so that trailer is not pushing against the truck. If the ball is being pushed into the latch mechanism if will be hard to unlatch. Pull forward before unhooking it on a level surface.

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


i had a deck over trailer that rode way too high making the the trailer ass heavy and caused it to sway. I removed the old one and welded this one on and now the trailer rides level and pulls amazing. The quick hookup feature on this is a must have as the ball seats perfectly every time. Great product and will definitely be getting another for my other trailer as it's coupler wears. 462048

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. 666913

Ask the Experts about this Demco Adjustable Trailer Coupler

  • How to Lock Demco 21K Adjustable Channel Trailer Coupler
    The Demco Adjustable Channel Trailer Couplers like the 21K # DM14040-81 use 5/8" diameter bolts for attachment to the adjustable channel, so you could potentially replace them with 5/8" locking pins like etrailer.com # e98881. Please keep in mind though that Demco does state that the standard Grade 5 mounting bolts # PS024202 do need to be used to achieve/maintain the coupler's 21,000 pound weight capacity. With this in mind I don't recommend doing this, as this could potentially lower...

  • Coupler Lock Recommendation for Demco EZ Latch Style Coupler
    The Demco Channel Tongue Trailer Coupler - Zinc - 2-5/16" Ball - 3" Channel - Bolt On - 18K # DM14040-81 has an integrated 5/16 inch pin hole with a 3 inch span for that lockable feature. I recommend using the Trailer Coupler Lock # e98888 which has a 3-3/8 inch span and is 1/4 inch diameter.

  • How to Lock the Demco Trailer Coupler Part # DM14040-81
    I do have a way for you to lock the Demco Trailer Coupler part # DM14040-81 but I am not aware of any device that will allow you to lock it using your own padlock. The only way I am aware that the trailer coupler can be locked is with a pin style lock like part # e98888 which can be keyed alike if you have other trailers or a wraparound style lock like part # DT25013KA which can also be keyed alike if you have other trailers. I wish I had better news for you.

  • Can Auto Latch of Demco Trailer Coupler # DM14040-81 Be Operated with Pin Lock In Place
    If you had a pin lock inserted in the coupler part # DM14040-81 that you referenced it would not auto-latch onto the hitch ball. The latch portion would not be able to slide up to let the ball pass. If you check out the picture I attached you can see that the pin hole would prevent that.

  • Recommended Lock for Demco eZ-Latch Coupler
    To secure your PJ Trailer that's equipped with the Demco eZ-Latch Coupler # DM14040-81 I highly recommend the Fastway Universal Trailer Coupler Lock # DT25013KA, which doesn't require a lip on the coupler for a proper connection. This is a heavy-duty lock that uses a ball and shackle to prevent potential thieves from coupling their truck to the trailer and taking off. Its hardened chrome-plated construction will resist corrosion and the bolt-blocked locking system prevents the lock from...

    Since the Demco Trailer Coupler # DM14040-81 that you referenced has a lock pin hole with a diameter of 5/16" and a minimum span of 3" for the pin lock, the BOLT Trailer Coupler Lock # BL7025285 that you referenced is compatible. The pin diameter is 5/16" and it has a 1/2" - 3-3/8" inside pin length span.
