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.

Video Transcript for Demco Straight Tongue Trailer Coupler - Standard Coupler - DM12717 Review

Today we're going to be taking a look at Part Number DM12717. This is the Demco Channel Tongue Trailer Coupler. The straight tongue coupler is made of a sturdy steel construction. It's going to have a corrosion-resistant zinc finish with a 200 hour salt spray rating. It is a bolt-on installation, and it's designed to bolt onto your 3 inch wide trailer tongue. The channel tongue coupler is going to let you hook up your trailer to your tow vehicle, it's going to provide the connection point for your 2 inch hitch ball.

It's also going to feature an easy latch coupler mechanism that's going to ensure simple, secure hookup and disconnect. The great feature of the easy-latch system is it's going to let you hook up when the latch is in the closed position. All you have to do is drop the coupler directly over the hitch ball and the latch is going to automatically snap into place. Now, to disengage, all you have to do is pull up on the trigger latch mechanism, so it's got that trigger latch function. If you do not hit that trigger, the lever's not going to open. If you push up on the trigger, now the lever will open, and it's going to automatically release the grip on the hitch ball. Again, a heavy duty steel construction, bolt-on installation, hardware's not included.

It's going to feature a 4 mount hole design on each side. Go ahead and take a measurement of those holes. They're going to give us a diameter of a half-inch. The distance that we have center on center between these 2 is going to be 2 inches. Center on center between this one and this one's going to be 3 inches, and then the diagonal measurement center on center between this one and this one, 1 and 7/8.

That's going to be the same between these 2 as well. This product's made in the USA, it's designed for 2 inch hitch balls, it's going to offer a weight capacity of 10,000 pounds. The overall length, measuring from the very front to the very back, that's going to give us a measurement of about 14 inches. Again, it is designed for 3 inch wide channel tongues, so if we take a measurement of the inside edge to inside edge right here, it should be just a little bit larger than 3 inches. That way it gives it plenty of room to slide over your 3 inch wide tongue. It looks to be about 3 and 1/8, so you'll place that over and then bolt it on to secure it. The last thing I want to point out, is I want to show you the mechanism on the inside, how that operates with the lever.

But again, the easy latch is going to allow it to connect to your hitch ball with the lever in the closed position. Then, you're going to notice a pin hole right here, located on each side, as well as a pin hole here on the latch. These are designed for the installation of a coupler pin and lock. That way, you can lock your trailer if it's unattended. It's going to keep anybody from being able to come up and run off with your trailer. You can also secure it once you have the connection made to your vehicle, and it's going to prevent anybody from being able to come up to your setup and disconnect. Those are there. Each one of those holes is going to have a diameter of 5/16 of an inch. If we measure the span here at the top, you're going to need a coupler pin with a usable length of at least, I would say, it looks to be right at 1 and 1/8, but you'll probably want to go with an inch and 1/4, just to be safe. Down here for this one, that's going to offer a span of about 2 and 1/2 inches. That's going to do it for today's review of Part Number DM12717. This is the Demco Channel Tongue Trailer Coupler for 2 inch hitch balls. .

No problems with coupler. Has performed excellent under some rather heavy loads. 313486

- DM12717

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. 667217

- DM12717

The easiest hitch I have ever used. 458013

Highly recommend. Would definitely buy again!!

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. 390075

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. 339808

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. 375374

Heavy duty, well made fit great and easy installation 671740

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. 732769

This product each on, easy off feature makes it much easier to get the trailer tongue onto and off the tow ball. All boat trailers should be equipped with it. 703061

Ask the Experts about this Demco Straight Tongue Trailer Coupler

  • 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...

  • 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....

  • 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...

  • 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.
