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.

Awesome coupler. You cannot forget to lick in your hitch ball with this. It automatically locks in place when you drop it on the ball and the flip latch is easy to release the ball when unhooking. There is a reason Airstream has this on all their new travel trailers



- DM14040-81

This is by far the best ball hitch I have ever used. It makes hooking up and unhooking a breeze.



- DM14040-81

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.

Looks like a great product but it would be nice to have the appropriate bolts with it or the associated brake actuator that I also bought.

I love Demco Couplers, they are so easy to use and so well constructed. I have been changing the couplers on all of my equipment to Demco. etrailer is the is by far the best place to get them, along with numerous other items like trailer jacks, lights, hitches, etc. Great customer service, fast shipping, great prices, what more could you ask?

I love how easy this coupler is to use! This last order completes replacement of the couplers on all my trailers. Highly recommend!

Excellent product, but even more is that after ordering within 3 days I received delivery. Unfortunately when I opened the box there was nothing inside and the box had been obviously related. I contacted customer service and was pleasantly surprised that not only did they understand, another was shipped out the same day! The best customer service experience in years! Thank you

I installed this on a trailer with a 2" ball so I wouldn't have to change the hitch in my truck as the other trailers are 2- 5/16. Highly recommend.

etrailer never fails me! Every time I order anything for my business from a different vendor, I cringe just a little not actually knowing what I’m going to get .. With etrailer, I always have the security of knowing exactly what’s coming AND that it will be here the next day. The finest quality and the best price. When ever I call to ask a question about a product, they give me prices, comparisons and if there is a sale item available, they tell me about it and give me a cost comparison to tell me how much money I can save. WHO does that?... NO one on this planet. Now, if they only sold new trucks...

Took a long time to get but I know it wasn't your fault

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

This receiver is a direct replacement for the Bulldog receiver. Much nicer, easy direct replacement. The bulldog gets clogged with rust and contaminents and this is much cleaner AND less expensive. Easy hooku. A MUST buy!!!!

Ask the Experts about this Demco Adjustable Trailer Coupler

  • Coupler Lock For Demco 5/16 EZ Latch Coupler
    For your Demco Trailer Coupler - Cast - Adjustable Channel # DM14040-81, I recommend the etrailer Surge Brake Coupler Lock # e98888, which has a 1/4" diameter and a 3-3/8" span. Its large span is ideal for 2 5/16" balls, and, can be keyed alike to match other etrailer branded products.

  • 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...

  • 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.

  • 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.

  • 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.

  • 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...

  • Recommended Lock for Demco DM14040-81 Coupler
    The # BLTL-23 Blaylock coupler lock is compatible with a very specific type of coupler, the CollarLok like our part # BD028499, so it wouldn't be a good fit for a coupler like the Demco # DM14040-81. A lock like the # DT25013KA or a latch type lock such as # 2847DAT would be your best fits.

  • Will The Blaylock EZ Coupler Lock Work With A Demco EZ Latch Coupler.
    I have a solution for you. The Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33 will not work with the Demco Trailer Coupler - Cast - Adjustable Channel - eZ-Latch - Black - 2-5/16" Ball - 21K # DM14040-81. You will need a coupler lock like etrailer Surge Brake Coupler Lock - 3-3/8" Span - 1/4" Diameter - Chrome # e98888. This can be used while coupled to a trailer or while off vehicle.

  • Is the BOLT Trailer Coupler Lock # BL7025285 Compatible with the Demco Trailer Coupler # DM14040-81
    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.

  • Replacement Actuator and Coupler for 2013 Jayco Jay Flight
    For the Jayco RD-19 you would use the Demco Hydraulic Brake Actuator - Drum - Primed - A-Frame - Adjustable Channel Center - 8,000 lbs # DM8759522 and then the Demco Trailer Coupler - Cast - Adjustable Channel - eZ-Latch - Black - 2-5/16" Ball - 21K # DM14040-81. Then use Hardware Kit for Demco Adjustable Channel Mount Couplers # DM6166.
