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.

Purchased to do away with trailer brakes. It worked perfectly!

Etrailer Expert

Katrina D.


Hopefully, you wont be needing those brakes. Some states do require, by law, that trailer brakes be used for specified trailer weights and or sizes. Now, if you are talking about switching over to electric brakes from hydraulic, that is a different story. And in which case, I am glad that this coupler is working well for you!


Used this coupler to replace my old surge brakes with an electric over hydraulic actuator. The old surge brake system was integrated into the coupler. This fit perfectly on my 3' tongue and aligns better than the original as this one sets down at the same level as the trailer tongue, not on top of it. The original was 3" higher at the ball which caused my trailer to ride low at the front. The coupler matched up perfectly with the two existing predrilled holes in the tongue, and I drilled two more to utilize (lower all one and 3rd one back on top) all 4 bolts. One thing that was unexpected is that the pin length is longer than the short length bolt cutter proof locks I like to use, but I'm sure I will find an acceptable replacement. There is a secondary pin lock hole that uses available pin locks which I have not tried and have seen questionable reviews for.


This new Demco coupler replaces a lower version Demco plastic handle coupler that came with the trailer. I constantly struggled to uncouple from the ball and at my age it was not a good situation. This better-quality coupler easily uncouples from the ball with no more issues.


works as advertised. auto latch feature is great



Works as new. Great product!!!


Great Coupler, I have a 7000LBs trailer that had a light duty Coupler easy upgrade.


Heavy duty, well made fit great and easy installation

by: 08/25/2023

Fit perfectly, exactly what I needed. High Quality.


Purchased this coupler for a tandem axle 8000lb boat trailer, one of the few 2" economically priced couplers available with a rating of 10,000lbs. This is well built with staggered mounting holes my tonge is 3"x5" galvanized tubing. This coupler has a auto latch feature and a standard pin lock for the latch. Better than expected quality, would strongly recommend for 10k tube tonge application.


I got exactly what I thought I was getting it bolted on nice I replaced the juice brake tongue changed over to electric brakes everything went well It has an interesting design where you don’t have to mess with the coupler you just set it down on the ball and it locks in place and then drop the safety pin through . It’s sitting in the weather no signs of rust or corrosion


Good product. I put this on so I cold use electric over hydraulic brake system, No more surging for me. also went to 2 inch ball so I standardized all my trailers. Still has the gross weight capacity that is required.


This hitch is exactly like the hitch I needed to replace on my towable lift. The original hitch had a slight bend in it and I did not feel that it was safe to tow the lift. The bolt pattern matched up almost perfectly. One hole is a little off, but very workable. The hitch is well made and will serve its purpose well. The correspondence was excellent between the seller and me. It arrived to me in a timely manner and was well packaged.


I purchased this to replace the factory coupler on my trailer. The new Demco allows me to lock the trailer in more then one configuration. Bolts transferred from old to new, and fit well. Reason for a rating of 4 stars due to the price point.


The heavy duty boat trailer coupler finally arrived yesterday ,due to the crazy east coast weather UPS had a time with delivery. What a great coupler that is . I can't wait to install .Dealing with your ordering system was a snap and the selection of products is unmatched by all.
Thanks and I shall return


Have no installed yet but hitch appears to good. The price was great and very fast shipping



Great product


Etrailer rocks... George j shipped it right away... Awesome online company.. Don't get caught paying over priced items from your local dealer... Good pricing for top quality products

Thank you we will buy here always

James A.


It turns out to be one of those things you did that you just never have to worry about ever again... Cant be happier to have upgraded this hitch... Looks and works perfect!!!!! No more reverse hydrologic issues... Flawless


Crazy GOOD SERVICE. I ordered a trailer tongue Monday afternoon and when I got home from work on Tuesday, It was at my door. ORDERED AND DELIVERED IN LESS THAN 24 HOURS. UNBELIEVABLE. First time purchaser. I have four trailers and etrailer is now my trailer parts go to company. These guys are amazing. A++++++ Thank you, Richard.


I was tired of fixing brake pistons and associated parts in a hydraulic coupler. I mounted this and have had zero issues. No regrets.


Yes heavy duty and the easy latch system is a great idea. Easy Bolt on installation. Just drop the coupler on the ball and automatically latches.


It just arrived and I will put it on today Excited to get rid of the old surge brake hitch assembly


Works great.


Works like a charm and will handle the 10,000 lbs. on a 2" ball. Love it, I can keep all my stuff on a 2" ball without worrying.


Trailer coupler work great and bolted right to my EZLoad Trailer.


I was impressed with the efficiency that my order was processed and the company website is really straight forward to research what you are looking for. Haven't had the opportunity to get the new coupler on the trailer ,with the weather as it is but I'm sure it will be great.


This is exactly what I needed and, the ship time was extremely fast. Thanks etrailer


Hitch coupler is well built and has an excellent finish.

See what our Experts say about this Demco Straight Tongue Trailer Coupler

  • Replacement Trailer Coupler with 6-1/2 Inches Between Bolt Holes
    The Demco Channel Tongue Trailer Coupler # DM12717 mentioned in your question is going to provide the closest bolt hole dimension to the existing coupler on your trailer that we currently have available. The distance from the front mounting hole to the rear mounting hole is 5 inches on center. When installing the coupler on your trailer, you should be able to use the existing holes on the trailer tongue for the front bolts. You will then just need to drill new holes for the remaining bolts....

  • Can Surge Brake Actuator be Locked to Convert to Electric Over Hydraulic Brakes
    You can lock out your surge brake actuator although it's not always the prettiest of solutions. You need to either weld the pieces together or drill holes through it putting in bolts to keep it from moving. It'll work but it completely destroys the actuator from ever being functional again. On the other hand drilling holes into the Demco coupler, part # DM12717, is a better option. Drilling isn't ideal but once you put bolts through it you'll keep its integrity intact.

  • What Grade Bolts Are Recommended To Install Demco Channel Tongue Trailer Coupler
    I recommend using Grade 5 1/2" x 4" bolts to install the Demco Channel Tongue Trailer Coupler part # DM12717. These would allow for the full weight capacity of the coupler to be achieved. These can be picked up at most local hardware stores.

  • Total Length of the Demco Channel Tongue Trailer Coupler # DM12717
    The total length of the Demco Channel Tongue Trailer Coupler # DM12717 is about 14". I have attached a photo and a review video to demonstrate this. Trailer tongue couplers like the Demco that you referenced are designed to fit on trailers and so you want to make sure that the 3" channel is correct for your application. It should work just fine with your 2018 Ford F-150 as long as you have a 2" hitch ball you are using. If you have special circumstances or can let me know why you are wondering...

  • How Does the Bolt Pattern on the Demco DM12717 Coupler Measure?
    I had the Demco Channel Tongue Trailer Coupler - Zinc - 2" Ball # DM12717 measured and included a diagram with the spacing you are looking for, and a little more if needed. With that being said, from the center of the first bolt hole to the center of the last bolt hole, it will be 5 inches. I should also mention that this is designed to fit a 3 inch wide channel tongue and is rated up to 10,000 pounds towing. The zinc plating offers corrosion resistance and has a 200 hour salt spray rating....

  • Comparing Demco Channel Tongue Trailer Coupler 12564 and DM12717
    The only difference between the Demco Channel Tongue Trailer Coupler part # 12564 and Demco Channel Tongue Trailer Coupler part # DM12717 is the bolt pattern which is just slightly different with one having an extra hole.

  • Coupler Replacement Compatibility Moving Up in Capacity
    Using a longer and heavier duty coupler is fine, but your trailer capacity will still be limited by the weakest component. So even if you have the # DM12717 coupler, the total trailer capacity may still be 3,500 lbs based on the axle, springs, hubs, frame, etc.

  • Recommendation for a Coupler Lock Compatible to the Demco Channel Tongue Trailer Coupler
    For your Demco Channel Tongue Trailer Coupler for 2 Inch ball, # DM12717, I recommend the Master Lock 1-7/8, 2, and 2-5/16 Inch Trailer coupler Lock, # 377DAT. Unlike the Fastway Universal Trailer Coupler Lock, like # DT25013, the Master Lock coupler lock will fit up into the trailer coupler and uses a sliding lock that secures over the Demco coupler lip. The Master Lock trailer coupler lock is nickel-plated die-cast zinc that will resist rust and corrosion.

  • Is There a Trailer Coupler for 50mm Hitch Balls That Can Support Over 5,000 Lbs
    I do have straight tongue trailer couplers that will work with a 50mm hitch ball and I do have straight tongue trailer couplers that can support 7,000+ lbs. That said, I don't have one that can do both as you are around the max weight for a 50mm hitch ball and could even be over in some cases depending on your exact hitch ball so be sure to check the top. The trailer couplers we offer compatible with 50mm hitch ball like the Titan Trailer Coupler part # T2343400 max out at 5,000 lbs. Therefore,...

  • Will 3 Inch Channel Coupler Work With 2-1/2 Inch Trailer Tongue?
    The Demco Channel Tongue Trailer Coupler - Zinc - 2" Ball - 3" Channel - Bolt On - 10,000 lbs # DM12717 will not work on a 2-1/2 inch tongue. Instead I recommend the Fulton Fas-Lok Coupler, 2" Ball, 2-1/2" Channel - 3,500 lbs # F222500301 or etrailer option # CT-3002-Z. Either of these options will fit your tongue and will work with the 2 inch hitch ball. The weight capacity is significantly less with the couplers that fit 2-1/2 inch tongues so please note that difference.

  • Trailer Coupler Recommendation that Fits 2 inch Wide Trailer Trailer Tongue
    While Demco does not have a coupler that fits on 2 inch wide trailer channel we do have the etrailer part # CT-2001-Z that does fit that channel size and would work great. It has a trigger latch design that is very common and works great.

  • Can Hydraulic Surge Brake Actuator be Locked Out for Electric Brake Conversion
    The Demco Channel Tongue Trailer Coupler # DM12717 and other tongues like it are meant to be mounted on the outside of the frame. None of our couplers will fit a 3-1/2" frame so it would be better (and more cost-effective) to just lock out your older hydraulic coupler. We do have everything that you need to convert your trailer from hydraulic to electric brakes. I have attached a helpful article that shows everything you need. If you let me know what size axle(s) you have I can make some...
