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. 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

Unlike most couplers, which only have a pin hole on the handle latch, the eZ-Latch coupler features a hole on the latch and 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 silver powder coat finish that is designed to limit rust and corrosion. This finish has a 500-hour salt spray rating, making the coupler perfect for marine use.

Video Transcript for Demco Adjustable Trailer Coupler - Coupler Only - DM15791-52 Review

Today we're going to be taking a look at the Demco trailer coupler. This is a cast ball coupler that lets you hook up your trailer to your tow vehicle. It's going to provide a connection point for a 2 5/16" hitch ball. It's going to feature your easy latch mechanism that's going to ensure simple, secure, hookup and disconnect. Simply lets you hook up when the latch is in the closed position. All you got to do is drop the coupler over the hitch ball, and then the latch will automatically snap into place, and it'll engage the hitch ball.

If you want to do it the traditional way with the latch in the open position, this coupler offers that feature as well. Again, the easy latch design lets you hook to your hitch ball with the latch in the closed position, and it engages automatically. When it comes to mounting, this is designed for an adjustable channel mount. It's got that design to it that's going to let you change the coupler's height depending on your application. Your channel bracket and mounting hardware are sold separately. When it comes to the hardware, we want to recommend using part #DM6166.

It's available, right here, at etrailer.com. This is made from a sturdy steel construction. It's going to feature a really nice silver powder coated finish. It's going to do a great job at resisting rust and corrosion, looking nice, and lasting for a long time. It's going to feature a 500-hour salt spray radium which is going to make this ideal for marine applications. It's SAE J684 certified.

This is designed for a 3" wide channel bracket. We can tell that by taking a measurement, here, at the backside. You can see that's going to measure right around 2 7/8, so it's going to fit perfectly inside the 3" wide channel bracket. Again, it is designed for a 2 5/16" hitch ball. It's going to offer a weight capacity of 21,000 lbs.

The overall length of our coupler measuring from back to front is going to give us measurement of about 8 1/8" long. You can see the wedge mechanism right there. Open and close the latch, and you can see how that controls the wedge. Another neat thing I want to point out is this unit's going to feature two lockable, or pinhole, locations for a coupler lock. You're going to have your traditional one, right here, on the latch, that would prevent the latch from opening up. If you're interested in a coupler pin and clip, or pin and lock, those are going to be sold separately. They are available, here, at etrailer.com. You're going to have this location, right here, and you're going to have a location, down here, that actually locks the wedge into place. That way nobody could connect it to their hitch ball, and it can't become disconnected when it's connected to your trailer, to your hitch ball. If you want to use this location, right there, these holes are going to have a diameter of 5/16". You're going to need a usable pin length, or span, of 1 1/8" for this location. For this location, you're going to need a usable pin length, or span, of 3". That's going to do it for today's look the Demco trailer coupler for a 2 5/16" hitch ball.

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

Review from a similar 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 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

Excellent design, the only small issue is that the top of the coupler that fits over the ball is already rusting. 526058

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 eZ Latch in Adjustable Trailer Coupler


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

Trailer coupling will not fit correctly on a 2" Ball...to tight and is always difficult to get on and off. 440928


Comments
We have contacted the manufacturer and they suggest pulling forward so that trailer is not pushing against the truck. If the ball is being pushed into the latch mechanism if will be hard to unlatch. Pull forward before unhooking it on a level surface.

Review from a similar eZ Latch in Adjustable Trailer Coupler


My old coupler was pretty used up and rated at only 5000 lbs for a 10,000 lb trailer so it had to go. The new bolt-on 10,000 lb coupler is quality. I like the EZ latch because its smooth, self latching and easy. The job was about four hours including removing old coupler, welding some new channel in and drilling holes. New coupler looks good, works great, and trailer is safer. 703091

Review from a similar 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

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

  • Locks and Channel Recommendation for Demco Trailer Coupler # DM15791-52
    The Demco Trailer Coupler # DM15791-52 does not come with the locking pins or the mounting pins. The mounting pins will need to be supplied by you. Grade 5 mounting bolts must be used to achieve the 21,000-lb weight capacity and we do not carry them. For the body of the coupler the lock you'd need is # e98888 and for the pin you'd want # e98883. If you select keyed alike on the drop down menu you'll be able to order them both with the same key number. For a channel to use with this...
