eZ-Latch Coupler

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

Unlike most couplers, which only have a pin hole on the handle latch, the eZ-Latch coupler features a hole on the latch and 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 red powder coat primed paint 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.

Super fast shipping.



by:

Great product, we made some extra supports from scrap steel.



by:

Shipping was on time. Quaility excellent. Bolts for mounting hitch to receiver were to long. Additional lock washer and easy install. Really easy to use!



by:

Simple design, sturdy hardware, wish it came with just two long bolts vs 4 shorter ones for when you adjust the height though.



by:

Just what I needed. Great coupler we had one on another trailer and liked it so much we had to get another one.



by:

This is the third one I've bought. You just back up, drop it on the hitch and it's hooked up.!) To disconnect, you just lift the lever handle (so smooth and easy) and it's loose. Eliminates all the frustration and works smoothly. Great product!



by:

Great product and really fast shipping. Which is what I needed for my business!



by:

Definitely.A great hitch would have liked to see a pin to hold the latch down. Otherwise great product really heavy duty



by:

Heavy Duty Fast shipping



by:

Excellent coupler. Fit my single axle trailer with the adjustable channel mount. Makes connecting the trailer to my ATV or car super easy. Much better than a regular coupler that is difficult to engage and disengage.



by:

perfect fit and a big upgrade to my stock coupler.



by:

Best coupler I have found. Have converted three trailers to these. When moving a trailer with a ball hitch adapter on a piece of equipment (3-point hitch on a tractor in our case), the auto-latch feature lets you attach to the trailer without getting off the machine.



by:

solid build, heavy.
This is installed
on a dump trailer so we needed a cast hitch--the original was steel and the gusset underneath bent with use and abuse to the point of only being functional with the aid of a 5LB hammer.
I had to grind a little on the back end to make the bolts align to both holes (maybe 1/16th?) but other than that, it is a step up from the original hitch.
Yes, I know this will void any warranty.



by:

Great replacement coupler, however be aware it does not include the pin lock. So essentially it is non usable until a pin lock is acquired. That in itself seems easy until you try and find a 5/16 diameter that is at least 3.5 inches long locally to use quick.



by:

This is a new brand to me. I'm installing for a client and wanted a quality fail safe coupler. This is it, very heavy duty, solid latching system. I expect years of worry free service from this coupler.



by:

Perfect addition to my new trailer.The original junk coupler was a pita to use.Had to use free hand to hold lock back while jacking up to remove trailer from truck.Honestly looking forward to using the trailer now.

I borrowed a trailer last year equipped with the Demco and it was my first experiance with it and I loved it so I bought one.I like the release handle yea its plastic but honestly dont see how a person could break it but Im sure it will be done but not on my trailer

Also like the fact that it will latch with lever down It does have hole for safety pin which I bought from local trailer shop.I encourage anyone looking at these couplers to watch Demcos YT video



by:

Worked perfect with the adjustable weld on channel. Was able to drop the ball coupler 10” from the old lunette height on an M1101 military trailer. Not a lot of fab work, just a couple of 3/8” plates and bolted them up and welded the channel on an bolted the ball coupler at the height I needed to level the trailer when towing with my Jeep Galdiator.

Very nice coupler. Smooth and easy to use.

NIce part, fair price, American made.



by:

Delivered quickly, fits perfectly!



by:

For someone who kept forgetting to engage the lock this item has been the best investment on my trailer. (Funny thing is once I put this guy on there I don't forget to check that it is engaged.) In the event I forget I know the coupler will be engaged and safe. As far as weight rating I have pushed this guy to almost 18k and seen no stress or issues with it. The components are holding up great after a year.



by:

WEll it fit, I had to eliminate the electric brake but I only tow it twice a year to the marina and back,about a total of 25 miles. It works . Better then paying $500 for the whole package with the electric brake.

See what our Experts say about this Demco Adjustable Trailer Coupler

  • Is there a Way to Replace Slide On Demco DA91 Disc Brake Actuator For No Coupler Drop?
    We do have the Replacement Inner Slide # DM12808-97 you could use with the Demco Trailer Coupler # DM15791-97 on your Demco Hydraulic Brake Actuator # DM8750311. This would allow you to position the coupler at several different heights to best level your trailer. Otherwise you would have to drill new holes for the Actuator # T4747220 which has a straight coupler out of the actuator.

  • What is the Mounting Hole Width on Demco 21K Trailer Coupler DM15791-97
    Demco coupler # DM15791-97 is designed to fit a 3 inch wide channel bracket such as # DM59602. On the coupler where it mounts to the channel the distance from the outside of one flange to the other is approximately 2-7/8 inches. I have included a picture illustrating these dimensions for you. The holes on both are space 2 inches apart on center (vertically) and are 5/8 inches in diameter.

  • Is Demco Hydraulic Brake Actuator DM8759432 Bolt-On or Weld-On
    While we do have a bolt-on option, the Demco Hydraulic Brake Actuator - Drum - Primed - 12" Adjustable Channel Down - 8,000 lbs # DM8759432 is actually a weld-on actuator. If you are looking for a bolt-on option, there are a couple similar options: - Demco Hydraulic Brake Actuator - Drum - Zinc - 12" Adjustable Channel Center - 8,000 lbs # DM8758521 - Demco Hydraulic Brake Actuator - Drum - Zinc - 8" Adjustable Channel Down - 8,000 lbs # DM8759231 Your 11 inch channel is more than long...

  • A-Frame Surge Brake Coupler Recommendation to Replace HydroAct Actuator
    From a previous question we know that the actuator you have is a HydroAct brand and based on that we know the master cylinder you mentioned won't fit it. For a similar A-frame style coupler that will work great as a replacement we have the A-Frame Brake Actuator # DM8205222 which would be a great choice as a replacement. For a coupler then you'd want the # DM15791-97.

  • Does the Demco Trailer Coupler # DM15791-97 Have to be Painted
    The coupler part # DM15791-97 that you referenced comes primed for paint, but if you didn't want to paint it you could leave it as-is. A better option would be the galvanized version of this # DM07678-95.

  • Best A-Frame Disc Brake Trailer Coupler Actuator
    I do have an option for you but there is not a version of the Titan Zinc-Plated A-Frame Brake Actuator for trailers with disc brakes. The only a-frame trailer coupler we do offer for use with disc brakes is the Demco Hydraulic Brake Actuator w/ Lockout part # DM8105422 so this is what I recommend. In order to use this coupler with a 2-5/16" hitch ball you will also need the Demco Trailer Coupler part # DM15791-97. The Demco coupler will actually be an upgrade over the Titan coupler. It...
