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 grey powder coat primed paint that is designed to limit rust and corrosion. This finish, which allows for easy welding, 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.

ETrailer has great customer service. On a time crunch I had to locate a coupler replacement for my Marvel which as been in service since 1999 and was past needing replacement. The staff, in particular Jena when na seers my call for help over the phone and quickly solutioned a Demco which doubled the capacity. The coupler arrived as promised and "on time". This Demco is a far superior improvement and design. Although if is a variance from "original" on our Airstream, it is worth the change. The coupler appears is much more substantial in design and allows adjustment. The fit was perfect angle and welded cleanly and is a great replacement for the Marvel which is marginally sufficient. The ONLY thing to be aware of is the jack hole is further rearward probably will not match your trailer bottom hole as didn't on this install requiring fitting of a fix relocating lower plate

C F.


As reviewed initially, the coupler remains a far superior product. My ONLY issue being placement of the tongue jack hole. It is likely there for more forward clearance. Great product and service


High quality, heavy duty hitch arrived very fast. I love that you can order a replacement latch and I will never have to cut this one off just because the latch wears out. The product arrived in excellent condition. The mobile welder said it’s cheaper to go to a shop versus having a mobile welder come out but I cut the old coupler off before I knew that.


Demco couplers are the bomb!!


works great


Very Good Quality! Awesome!!


The Demco coupler is 5*. I gave you 3* because you have an issue with your shipping dept. The coupler was just tossed in a box with no way to secure it. It arrived with the box blown open. The coupler was undamaged because...well it's made of metal. A previous order with you was for a trailer cover. That box arrived with so many staples in it, there was no way one had not gone through the cover. Many did go through and to your credit you replaced the cover. So as I see it 5*s for your site and products and 1* for your shipping dept.


Very solid. Will purchase again for sur e.


Product is well built and as advertised. Shipment was prompt and arrived on time. 4 stars due to a thin cardboard packaging that had several holes and a few scapes in the product. I am welding this on and painting afterwards so it's not a major issue.


I called and told you that it will not discount by pulling up on the plastic handle. You fell like your going to break the plastic. Your customer service past the buck and sent me to the manufacture. They have done nothing. I have to take a rod and gently beat it up from the bottom to remove the trailer from my F550 truck. If it was not welded to the trailer and the fact I leave it connected to the truck and only remove when loaning the trailer or sending the truck to the dealer for inspections and repairs I would have replaced it. this is the said part all I wanted was to purchase a rebuild kit for it.


Had a welder remove and install the new hitch. I love it because it's so easy to use.


Great service, fast shipping!


This is a great product! Working with a local welding shop to get this attached to my 2017 Airstream trailer. Much better than the OEM coupler.



Fantastic! I wish Airstream would consider using this as the OEM coupler.


I am a big fan of Demco, I have been changing out old couplers on all my trailers with Demco.
They are so easy to use and work great!
etraler is the only place to buy them from, their prices are great, fast shipping, and phenomenal customer service.

  • Can a Weld-On A-Frame Trailer Coupler be Bolted On Instead of Welded
    The A-frame couplers we carry, like # 12660-97SP, are weld-on applications and cannot be bolted on to a trailer frame. Any welding should be done by a qualified welder in a shop that works on trailers. The coupler you have reference accepts a 2-5/16 inch diameter ball. I have included a link to all of the A-frame coupler options for you to view.

  • Can Demco 50 Degree A Frame Coupler Replace an Underslung Coupler
    Yes, you can remove your current underslung coupler and install the Demco 50 Degree A-Frame Coupler part # 12660-97SP in place of it as a top mount without any issues. It would just attach to the top instead of the bottom. Worst case scenario you might need to use a ball mount with less drop.

  • Does Demco eZ Latch Style Coupler Have Flimsy Plastic Latch System
    I can certainly understand how the latch of the Demco 50-Degree A-Frame Trailer Coupler # 12660-97SP might seem easily broken, but it's not made from a cheap plastic that would be brittle and easy to break. It's made from a nylon composite that more closely resembles a hardened rubber which will be very durable and has the unique characteristic of not corroding like metal would. We've had no customer report back that their latch was broken also.

  • How Wide is the Opening on the Back of the Demco A-Frame Coupler 12660-97SP?
    The back of the Demco A-Frame Trailer Coupler item # 12660-97SP is 10-3/8" wide. I have linked a diagram below I made along with a review video.

  • Is the Demco Coupler part # 12660-97SP Considered Class V
    The various classes for hitch related products are assigned a designation to help organize them by capacity. The Demco Coupler part # 12660-97SP has more than enough capacity to be considered Class V (5), but couplers don't get the classification. This coupler has a 21k capacity which would be incredibly high for a bumper pull type coupler.

  • Are 50 Degree A-Frame Couplers Standard for A-Frame Trailers
    The 50 degree a-frame trailer angle is the standard angle for a-frame trailers so it would be almost guaranteed that this Demco Coupler part # 12660-97SP would fit perfectly. I don't have a way to open your picture but as long as the frame members of the a-frame look to be 50 degrees (or you can use an angle finder to verify) this would fit.

  • Demco Coupler Part Number 12661-97 Replaced by Demco 12660-97SP
    The 12660-97 Demco 50-Degree A-Frame Trailer Coupler with Easy Latch and Jack Hole - Primed - 2-5/16" Ball - 21,000 lbs # 12660-97SP is replacing the 12661-97. It is the newer version of the same part. Because it is replacing the part you referenced, we don't stock the previous number any longer. The manufacturer will probably keep the former part until all their stock is out before removing the number from their site.

  • Does Demco 50-Degree A-Frame Trailer Coupler Bolt On
    The Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole - eZ-Latch - Primed - 2-5/16" Ball - 21K # 12660-97SP does not have any bolt information, with the reason being that this is a weld-on application and cannot be bolted on. I did cut out the relevant aspects of the weld-on info that is from the manual. I also added a link to a video review of the weld-on Demco 50-Degree A-Frame Trailer Coupler # 12660-97SP.

  • Replacement Trailer Coupler Recommendation for a 1995 Airstream Excella
    I recommend checking out the eZ-Latch Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole # 12660-97SP which is rated for 21K, fits a 2-5/16" hitch ball, and has the standard 50-degree bracket size. You'll want to double check what you have though to make sure this is a proper replacement. Without knowing the specifics of your current trailer coupler this is just an educated guess in all honesty.

  • What is the Weight Capacity of Demco A-Frame Trailer Coupler, # 12660-97SP
    The Demco A-Frame Trailer Coupler, # 12660-97SP, has a weight capacity of 21,000 pounds. This coupler is the highest rated A-Frame coupler for a 2-5/16 inch ball that we carry. Otherwise, we have some flat plate couplers capable of 25,000 pounds such as # BD4425000317.

  • Which Is Better a Cast Steel or Stamped Steel Coupler
    Both styles of Demco couplers are going to hold up well but in general cast steel is considered to be better due to it's uniform and more consistent structure it provides. Stamped steel is typically considered a more cost effective solution due to lower production costs and quicker lead times. With that said the # 12660-97SP is cast and has a 21k capacity.

  • Is There a Reason Demco 50-Degree A-Frame Coupler # DM15349-52 is Silver
    Silver is just the color that Demco likes for their couplers which is why the Demco 50-Degree A-Frame Coupler # DM15349-52 is that color. The two most popular colors are black and silver like this. Demco does offer a red primer version of some couplers like # 12660-97SP.

  • Replacement A-Frame Trailer Coupler For 1978 Airstream With 50 Degree A-Frame
    It would appear that that your 1978 Airstream had the standard 50 degree a-frame style coupler. You can verify this to ensure that the etrailer A-Frame Trailer Coupler # CA-5280-RB will fit correctly on your Airstream. I personally prefer the auto latching style couplers like the Demco 50-Degree A-Frame Trailer Coupler # 12660-97SP. This coupler for me is cleaner and works simpler with the latching system. The connection for the jack has nuts welded on to the bottom of the plate making...

  • Can You Tighten An A-Frame Coupler Or Must It Be Replaced
    If you feel the connection point between your trailer coupler and hitch ball is too loose then the trailer coupler will need to be replaced because there is no way to tighten this. The connection point does need to be loose enough for the coupler to rotate on the hitch ball but not loose enough where you have a bunch of play. If you are in doubt it would be wise to replace the entire trailer coupler for both peace of mind and security. In some cases, you can obtain a trailer coupler repair...

  • Recommended Lock for Demco A-Frame Coupler # 12660-97SP
    To help protect your trailer from theft I highly recommend the Master Lock Trailer Coupler Lock # ML389DAT, which will work perfectly with its Demco A-Frame Coupler # 12660-97SP. The lock will secure inside and around the coupler to keep somebody from hooking it up a different tow vehicle. I particularly like the bright red finish on the lock that does a good job of preventing potential thieves from even trying, as it's a clear indication that a lock is in place.

  • Is There a Repair Kit For a Thumb Latch Coupler # CA-5400-B?
    Currently the only way to replace the coupler mechanism on the A-Frame Trailer Coupler # CA-5400-B is to replace the entire coupler. If you are going to do this you should look at changing to the Demco 50-Degree A-Frame Trailer Coupler # 12660-97SP as it is much easier to use and can be repaired with the Repair Kit # DM6008 in the event it breaks down the road.

I cannot locate anyone who carries a replacement latch mechanism for the A-Frame Trailer Coupler # CA-5400-B. With the Demco you can easily replace the latch with the Repair Kit # DM6008. It is also auto latching so you will only need to open the latch when disconnecting your trailer.

However, it can also be used to pull a 5th wheel camper that has been converted to connect to a gooseneck ball with something like the Reese Goose Box # RP85FR. With that being said, the # BWHB94006 should not just be attached to the bed of a standard 2005 Ford F-150...
