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.

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

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... 763951

Review from a similar eZ Latch in Adjustable Trailer Coupler


The coupler would come loose unless it was pinned before I loaded my tractor on the trailer. This coupler stays open when hooking up and closed when in use. 452345

Review from a similar 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 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 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

Review from a similar eZ Latch in Adjustable Trailer Coupler


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 eZ Latch in Adjustable Trailer Coupler


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 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

Review from a similar eZ Latch 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. 666913

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! 303568

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...

  • 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.

  • 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...

  • 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.
