Video Transcript for Review of Demco Gooseneck Coupler - eZ-Latch Coupler with Inner Tube Only - DM73KV

Hi everyone. Steven here with etrailer.com. Today we're looking together at this Demco Easy Latch gooseneck coupler. Now, this is a round inner tube. It fits a standard two and 5/16 inch gooseneck ball, and it's rated at 30,000 pounds gross trailer weight. Now this is what's called an easy couple, or easy latch, and if you're not familiar with them, basically all you have to do is just literally set this down over the top of your gooseneck ball, and it's gonna automatically lock, couple, and be connected on itself, just because you put the weight down on it.

And I went ahead and got a two and 5/16 inch gooseball to show you this. So basically, you got your ball set up on the gooseneck itself, or in the truck rather, and then the gooseneck coupler just comes straight down. (coupler clicking) And as you heard it click, the weight of everything connected. I'm gonna tilt it to the side so you can see it, and now it's not going anywhere. And then to disengage it, all you literally have to do is pull this lever up, and then turn your, or you know, twist your jack, and it's gonna come right off.

So very easy to use. I'll show you that one last time. Again, lever's down, just drop the gooseneck over the ball, automatically engaged, it's not going anywhere. And then to disengage, pull the lever. And as you can see the mechanism inside moved out of the way to then let that engage.

But it does it automatically, which is really nice. I like that on this particular one. So again, if you've never used easy latch couplers, that's how they work. Pretty simple design, pretty simple concept. You do have four holes here.

The space in between those holes is two and three quarter inches apart on center, giving you a total adjustment of about eight and 1/4 inches. Now, from the top of here, all the way to the bottom lip, I got 28 and 3/4 inches long or tall, however you want to word it. And this again, is your standard inner tube, and the outer diameter here across is four inches. So you would need an outer tube already on your trailer. If you don't have one, we sell 'em here separately. Now this is a black powder coat finish over a nice hardened steel. It's gonna resist rust and corrosion. And it's very easy to use, as I just demonstrated for you. So if you're looking for a new inter coupler, this might be a a good option for you as far as ease of use and those kind of things. Well folks, that's gonna wrap it up for our quick look together. I'm Steven. As always, stay safe while you're towing. Thanks for watching.

Great, well built coupler. I was looking to get my trailer level and this gained me about two inches. Trailer is being pulled by a 5500 with a dump bed.

  • Replacement Inner Tube Gooseneck Coupler 4" Diameter For BullDog Bx1 25k
    Hey there John, I can help you out with this. While we don't have the specific Bulldog inner tube for the Bulldog BX1 Gooseneck Coupler - Adjustable Height - Round - 2-5/16" Ball - 25,000 lbs # BD1289000300, but Bulldog carries it under part number 1289020300. I'm working on getting it added to our site for you, but it may take a few days. That said, this is a pretty standard size (4" inner tube) so you can pair it up with a different brand inner tube like the Demco eZ-Latch Gooseneck...

  • Recommended Lock for the Demco eZ-Latch Gooseneck Coupler Adapter
    Hey Connor, there is no integrated lock for the Demco eZ-Latch Gooseneck Coupler # DM73KV but you can use the InfiniteRule Lock for Demco eZ-Latch Trailer Couplers # IR66FR to lock it, no Gooseneck coupler lock necessary. What kind of trailer do you have? If you have any other questions, please feel free to drop a comment and let me know!
