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 contoured handle and the coupler socket will automatically release its grip on the ball.

Demco eZ-Latch in Use

Sturdy, Corrosion-Resistant Construction

Made of sturdy steel, this coupler features a durable zinc coating that has a 200-hour salt spray rating, which is designed to limit rust and corrosion. The eZ-Latch's sleek, ergonomically designed handle is constructed of a durable composite material that's corrosion-proof, allowing it to withstand whatever the road and the elements dish out.

Video Transcript for Demco Straight Tongue Trailer Coupler - Standard Coupler - DM13203-95 Review

Today we're going to be taking a look at Part Number DM13203-95. This is the Demco Channel Tongue Trailer Coupler for 2 5/16-inch trailer hitch balls. The straight tongue trailer coupler is made of a sturdy steel construction. It's going to feature a corrosion-resistant finish, so it's going to offer excellent corrosion and rust protection. It's going to feature the Easy Latch Mechanism. This is going to ensure fast, easy secure hook-up and disconnect. This is designed to bolt on to your 3-inch wide trailer tongue. The channel tongue hook-up is going to let you hook up your trailer to your tow vehicle.

It's going to provide a connection point for your 2 5/16-inch hitch ball. The Easy Latch Mechanism is going to feature a corrosion-proof composite latch handle, very strong and durable and it contours perfectly to the front of the coupler, giving it a nice, sleek, clean look. The Easy Latch design is going to let you hook up when the latch is in a closed position, so there's no need to open that, although you can have it open and still connect. It's up to you, but the beauty of this system is you can connect to your trailer hitch ball with the latch in a closed position. All you have to do is drop the coupler over the hitch ball and the latch will automatically snap into place. Disengaging the coupler is just as easy. All you have to do is lift up on the contoured handle and the coupler socket is going to automatically release the grip on the hitch ball and allow you to disconnect. The unit is made from a heavy-duty steel construction.

Again, it's going to have that zinc finish and it's going to feature a 200-hour salt spray rating. It is a bolt-on installation. The hardware is not included. We're going to have the same bolt pattern on each side of our coupler. So I'll go over the dimensions of those bolt holes real quick. They're going to give us a diameter of 1/2-inch.

The measurement that we have center-on-center between these two holes is going to measure right on 3-inches. Center-on-center between these two holes is going to measure right on 2-inches, and center-on-center going either way at a diagonal measurement is 1 7/8-inch between these holes and this hole distance - so 1 7/8 from here to here and from here to here. Again, that's going to be the same on each side of the coupler. Again, this is going to fit the hitch ball size of 2 5/16-inch. The overall length of our coupler measuring from the very front to the very back is going to give us a measurement of 14 1/8-inch. It's going to have a weight capacity of 18,000 lbs.

The measurement here of the channel tongue that's going to give us a measurement of right around 3-inches, so this is designed for 3-inch wide trailer tongues. The last thing I want to show you - a couple of things, I just want to show you how that mechanism in there operates. You can see, again, Easy Latch, so once this gets dropped on the hitch ball it's going to connect automatically; and then to release you just lift up on the lever. It moves that mechanism up which is going to allow it to disconnect really easily. On each side of the coupler it's going to have a 5/16-inch diameter hole. This is so you can install a coupler pin and lock. A coupler pin and lock is going to keep the mechanism from being able to disengage from the ball. It's also going to keep the mechanism from being able to connect to a ball if it's not already connected. The measurement we have from outside edge to outside edge - this is also known as the span - is going to give us a measurement of about 3-inches. If you don't already have a coupler pin and lock you can find those right here on our website. This would also work with a socket lock. Socket locks go around the lip here and engage inside the ball socket. You can only use those when your trailer is disconnected from a hitch ball. The locks are all designed to prevent theft, so if you have the coupler pin and lock installed, and let's say your trailer's unattended. Nobody's going to be able to come up and connect to it. If you have this connected to your vehicle and you have the coupler pin and lock installed, nobody's going to be able to come up and disconnect your trailer and connect it to their set-up, so it's all about theft prevention. That's going to do it for our review of Part Number DM13203-95. This is the Demco Channel Tongue Trailer Coupler for 2 5/16-inch hitch balls. .

We raise cattle, so we don't have the luxury of a hardware store a block away. A friend told us of etrailer. GREAT folks to work with! Ordered what we thought we needed. It didn't fit. "No problem," returned it to etrailer and they helped us get the correct DM13203-95, 2 5/16 ball, 3" channel tongue that our draw-bar required. While talking with the folks at etrailer, they recommended the GT-1007 trailer document holders. These document holders have functioned very well, keeping the registration & license papers dry and free of mud, dirt & dust on our trailers so far - 110 degree summer heat, heavy rain / mud, gravel, snow, freezing night time temperatures and highway speeds. All are still in perfect working order. We have recommended etrailer to others and will continue to do so. Thank you etrailer for your knowledgeable staff, quick response time, and good pricing. 485062

The document holders are still in super shape, & of course so is the 2-5/16 coupler.

New coupler works great. Had to drill one hole that did not match up with old surge coupler but that was no issue. Here is before and after pics. Will definitely come to you guys for any other trailer needs. Thanks. 528262

When the OEM steel brake lines wore out on my boat trailer I decided to upgrade the surge brakes to electric over hydraulic (EOH). I replaced the damaged lines and wired up a Demco actuator and now I can stop my trailer on a dime. Although I could have continued to use the original coupler (surge) it was already quite worn and a pain to open. So into the trash it went and on went this nice new Demco 18K coupler. Now, even my daughter can uncouple the trailer. 546210

100 Satisfied!

We got a new trailer with a 2" coupler. All our vehicles have a 2 5/16" ball hitch. This solved the problem nicely, and arrived in only 2 days. Great service. 737911

I got this hitch coupler as a replacement for my boat trailer hitch. I wanted all my trailers with the same hitch size. This product worked perfectly and it has been over a year of use with no problems! I highly recommend this product! 725684

Good solid product, Easy to mount, and easy to latch to the ball, easy off. 647340

purchased this coupler to create an extension for my sailboat trailer that with together with the boat has a combined weight of 10,000 lbs. The coupler is rated 18,000 lbs and is heavy duty construction. It is pre-drilled (1/2" holes) to easily bolt on to a 3 inch box steel frame. I shop etrailer because of the thorough product descriptions, how-to videos, competitive prices and customer service. 646887

- DM13203-95

Great coupler. I got tired of swapping hitch balls on my truck, so I swapped this coupler onto my bass boat trailer. Now all of my trailers have the same size ball requirement. I like the easy latch system too, you don’t have to open it to latch it, just drop the coupler onto the ball and it auto latches. 640837

Ordering was simple and product came in just as expected...... 582705

Delivery was quick. Very well build. I had to drill hole to mount my safety chain because coupler was a little longer than the one that was on my trailer. I am very well satisfied with this product. 570807

fit 1st time and works great 560366

I ordered the coupler for my jet ski trailer. I was tired of changing back and forth between ball sizes so I standardized to 2 5/16. Cut the old one off, welded shins to the tongue, then welded the coupler on. I like the auto latching feature. 485302

- DM13203-95

Bought it so my trailers would have same size ball. Very easy to use. Just unbolted the old hitch and put this one on. Very pleased! 367230

We have bought an install a number of these couplers and they have worked very well for us 285011

- DM13203-95

Used this product to replace the original on the trailer which was a 2" coupler. I wanted a 2 5/16" coupler so that all of my trailers use the same size ball. With the adjustable height hitch I use, now I only need to adjust the height rather than changing the ball as well. This is a great product, very well built. I own eleven different trailers and the latch mechanism on this coupler latches and releases better than the others I currently use. I will buy another when the need arises. 256948

- DM13203-95

Great service. Item is as described and bolted right up to my trailer. 247527

  • Locating VIN on Top Brand Trailer
    Typically, the trailer VIN will be located somewhere on the trailer tongue. If you cannot find one there, check for plaques on other parts of the trailer. It may also be stamped onto the trailer frame itself. You will want to move the trailer around and check the underside, especially near the axle on the primary frame members. If you cannot locate the VIN on your trailer, your local state police or highway patrol should be able to assign a VIN for you.

  • Coupler Recommendation to Fit 3 inch Wide Coupler
    It's very unlikely your trailer has a channel that is 3-1/2 inches wide as that's not a common size at all. The part # 83010 that you referenced is designed to fit a 3 inch wide channel so what you would want is the # DM13203-95 which is a 18k coupler that would work well.
