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.

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.



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:

NIce part, fair price, American made.



by:

Very nice coupler. Smooth and easy to use.



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:

Awesome coupler!!! Lookin for a robust coupler…. Look no further!



by:

Solid construction, simple and nearly foolproof latching mechanism. Definitely an upgrade from the Apex coupler that came with my trailer.

One recommendation I have is that when installing this coupler (or most any coupler) in your trailer's C-channel, check the side play inside the channel and add a washer or two between channel and coupler to remove the slack space and get a solid fit.



by:

I have been using this on my 15,400# trailer since purchased no issues.Easily locks and unlocks .



by:

After having my trailer disconnect (yes, I had the right ball size) from a low-tolerance stock coupler, I replaced it with this one. The coupler works great. I've never had the lock mechanism bind like the cheap ones, it's taken a lot of the "slop" and jerk action out of towing, and it's certainly never come disconnected. Great product, and plan to have them on ALL future trailers.



by:

We have four trailers, all got converted to these couplers. Four bolts is a much better design than just two. Even my dad (who hates change overall) said, "These couplers are way better than the old style." They release easy and snap right into place. No complaints at all. We'll never go back.



by:

Excellent upgrade from the stock coupler. Simple to connect the trailer- just lower it and go. It looks great after a year as well. Not all dull and rusty the way cheap couplers get. Not exactly inexpensive but I would buy it again.



by:

Brilliant hitch. Holds up like a champ. Channel mount is a great solution for all sizes of trailers.



by:

Great upgrade to my heavy trailers. Would be 5 stars if the locking pin hole would accept a larger diameter lock or a padlock.



by:

A great upgrade to the original coupler that came with the trailer. All couplers work. This one is just easer to operate which comes in handy in bad weather. It also has a 5/16 hole for an additional lock or pin.



by:

The hitch is excellent for our 14,000lb equipment trailer.
Only issue is the hole for the padlock was too small for any locks and we drilled it out to accommodate one.
Con- Shipping was not very good. It was returned to the dealer twice because it was sent via United Postal Service and our shop has not Post office box. Only a location address. The USPS does not take packages to our location. We could not seem to get the package sent via UPS or FedEx to us.
Only time this has happened when ordering from etrailer.



by:

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.



by:

The ease of latching and not having to lift the latch handle is very nice and unlachine it's a breeze, works very well very happy with the coupler



by:

I really like this coupler! Very easy to use, no more fighting to decouple my equipment trailer. Simple to hook up.



by:

Was the perfect part to replace the pintle hitch that was previously on my 15K trailer.



by:

I ordered a black coupler set. You told me it would be available in several weeks, by Sept 20 something. I went online to look and you pushed the delivery out until late Oct or early Nov. I called and you actually have one in stock but it's white. I don't care about the color. I asked your rep to sell me the white one for the same price. He refused. How do you get $[XX] more for white??? I paid it as I need the trailer back. You are better than this.



by:

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!



by:

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!



by:

When in doubt go with demco. There almost cool proof. Also e trailer has competitive pricing!



by:

I didn’t use the bolts it came with. Just got two grade 8 bolts like my pj trailer came with, easier to adjust.

  • 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.

    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.

    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.

  • 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.

  • 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...
