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 Adjustable Trailer Coupler - Coupler Only - DM07678-97 Review

Today we're going to be reviewing part number DM07678-97. This is the Demco trailer coupler with the adjustable channel mount and the EZ-latch mechanism. The ball coupler is going to let you hook up your trailer to your tow vehicle. It's going to provide a connection point for your 2 and 5/16 inch hitch ball. It's going to feature the EZ-latch mechanism that's going to ensure a simple secure hookup and disconnect. The EZ-latch design is going to let you hook up to your hitch ball when your latch here on top of the coupler is in a closed position.

All you have to do is literally just drop the coupler over the hitch ball and the latch will automatically engage the ball and snap into place. Really neat system to have. The adjustable channel mount design is going to let you change the coupler's height depending on your application. Your channel bracket and mounting hardware are sold separately. Now this unit is made from a heavy duty steel construction with a nice primed finish. It's designed for 3 inch wide channel brackets.

So if we take a measurement from outside edge to outside edge that's going to give us a measurement of 2 7/8 of an inch. That's going to give us the room that we need to slide this into a 3 inch wide channel bracket. Now these mount holes, we take a measurement of those, the separation we have, center on center. They're going to be separated on 2 inch centers and they're going to give us a diameter of 5/8 of an inch. The weight capacity of this coupler is 20,000 pounds. One of the last things I want to show you is not only the mechanism here on the inside and how it operates with that trigger latch design.

So you can see when we push up on the lever it doesn't open, but when you engage the trigger and then open it's going to allow us to connect or disconnect from our hitch ball. Right here on the latch itself we're going to have a 5/16 inch diameter hole that runs all the way through the latch. Now that hole is there for a theft prevention. What we can do is we can install a coupler pin and lock. If you don't already you can pick one up here on the website. It's not necessary or required for this unit but it's going to add security and safety.

You can install your coupler pin and lock through this hole right here, again 5/16 of an inch in diameter. The span or the or the usable pin length that we would need on a coupler pin and lock, is going to give us a measurement of about 1 1/8 of an inch. But with a coupler pin and lock installed . let's say if you have it installed on your unattended trailer, nobody is going to a able to come up to it and hook it up to their set up. You can also attach our coupler pin and lock when you have this attached to your vehicle, and nobody's going to be able to come to it up and remove it from your setup and move it to theirs. So again, it's all about prevention. Then it's got the nice collar that goes around the ball socket right here. This will accept most coupler socket style locks and those can only be used on unattended trailers. That's going to do it for today's review of part number DM07678-97. This is the Demco trailer coupler for 2 and 5/16 inch hitch balls. .

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


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! 592298

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


The coupler is a fantastic, well built and easy to use unit. The installation was super simple. The coupler lock is a great piece as well, it fits great into the ball socket on the coupler and locks super tight. Great pieces of equipment. The coupler latch pin however did not fit the latch on the Demco coupler. Had to pick up a different one from Farm as Fleet, but we can use the other one on my other trailer. 126978

The coupler would come loose unless it was pinned before I loaded my tractor on the trailer. This coupler stays open when hooking up and closed when in use. 452345

Looks good, quality controle could be a little better. Nothing that will effect the function. It looks like it was not cleaned after welding. There is a lot of weld splatter. I am painting it a different color anyway so I will clean it up. 527512

I just got the hitch coupler. Will know more when it is installed in a week or so. Using the coupler, ball mount and hitch ball to upgrade my car hauler to 10K. 441561

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


Coupler mechanism is finicky, you have to shake the trailer tongue to get it to lock. The pin hole is too small in diameter to accept a lock so you have to use a ball lock to lock the trailer. Also it’s plastic so if it sticks you have to be careful tapping on it. I wouldn’t by again and if it breaks I’ll go back to normal coupler. 489782


Comments
The coupler mechanism is adjustable. Use the adjustment bolt on the underside of the latching mechanism to adjust until the coupler will self-latch when set atop the trailer ball.

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


i had a deck over trailer that rode way too high making the the trailer ass heavy and caused it to sway. I removed the old one and welded this one on and now the trailer rides level and pulls amazing. The quick hookup feature on this is a must have as the ball seats perfectly every time. Great product and will definitely be getting another for my other trailer as it's coupler wears. 462048

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


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. 463489

Review from a similar Demco eZ Latch in Adjustable Trailer Coupler


When my old coupler failed I was very happy to find a bolt on coupler this heavy as most are weld on for a trailer this heavy. I wish I would have changed the coupler years ago. I always had trouble with the old one. This one is so easy to latch and unlatch from my truck. It is great quality. 666913

Ask the Experts about this Demco Adjustable Trailer Coupler

  • What is the Mounting Hole Width on Demco 20K Trailer Coupler DM07678-97
    Demco coupler # DM07678-97 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.

  • Does the Demco Trailer Coupler # DM07678-97 Have to be Painted
    The coupler part # DM07678-97 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 # DM07678-97.

  • 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 part # T2492800 that is rated for use on 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 therefore this is what I recommend you use. In order to use this coupler with a 2" hitch ball you will also need the Demco Trailer Coupler part # DM07678-97. The Demco coupler will...
