Coupler Dims

eZ-Latch Coupler

Cast Coupler Cutaway

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

The contoured, low-profile design of the latch handle helps protect the coupler from damage by allowing any potential hazards - from debris on the road to your ball mount backing into the coupler - to simply slide over the top. This helps prevent anything from getting under the latch handle and releasing the ball, and it can also limit any damage to the coupler should an impact occur

Unlike most couplers, which have a pin hole on the handle latch, the eZ-Latch coupler features a hole 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.

The eZ-Latch's sleek, ergonomically designed handle is constructed of an impact-resistant polymer-nylon-resin compound that provides the flexibility and strength needed to bounce back from a collision. The handle is corrosion-proof, allowing it to withstand whatever the road and the elements dish out.

Video Transcript for Demco A-Frame Trailer Coupler - Standard Coupler - DM15633-52 Review

Today, we're going to be taking a look at the Demco 32-degree A-Frame Trailer Coupler. The A-frame coupler is going to let you hook up your trailer to your tow vehicle. It's going to provide the connection point right here for your trailer hitch ball. It's going to use an easy latch mechanism. What that does is that's going to ensure simple secure hookup and disconnect. It's going to let you actually hook up to the hitch ball with the latch in the closed position.

That's one of the things that makes this coupler unique from the others is that all you have to do is drop the coupler over the hitch ball and the latch will automatically snap into place. That latch mechanism is going to be constructed of a corrosion-proof polymer nylon resin composite. It's a nice strong durable design. It's impact resistant. It's got a nice sleek low-profile design. That's going to allow for hazards to simply slide over the top of the coupler preventing damage to the latch components. The unit is made from a heavy-duty steel construction.

It's going to have a good-looking silver powder-coat finish on it. It's going to offer excellent rust and corrosion resistance. This one does feature a 500-hour salt-spray rating, which makes it great for marine applications, and right here, it's going to have the built in jack attachment point. It's going to allow for quick easy mounting of a round utility jack. This is designed as a weld on installation. It is SAE J684 certified.

Again, it is designed for 32-degree A-frame trailers. It's going to fit a 2-5/16" hitch ball. It's going to offer a weight capacity of 21,000 pounds. There's a few measurements I want to go over with you real quick. The diameter of the jack hole back here, that's going to measure from edge to edge .. that's going to measure about 2-3/8".

That's going to work great for your 2-1/4" outer tube diameter jack. Then these holes, they're going to be spaced apart from one another on center by right on 3". That's going to be the same between each one. These holes are going to offer a diameter of 1/2". To detach the unit from your hitch ball, all you've got to do lift up on that latch. I'll show you that latching component right there. You would place this over your 2-5/16" hitch ball. It would automatically engage, and then to release, you just lift up that latch that lifts up the mechanism and that would release the hitch ball. This is lockable. Its got a small hole right here that's going to measure 5/16". That's going to be the same on each side. That's going to allow you to pass through a coupler pin or a coupler pin and lock so you can secure the unit and lock it onto the hitch ball or you can lock your unattended trailer so nobody else can connect to their hitch ball. A measurement we need to go over real quick with that is, you need to make sure that you're going to get the correct pin length. What we can do is we can just take a measurement of this area right here. From edge to edge, you can see that that's going to measure pretty close to 2-3/4". I would recommend a coupler pin with a usable pin length or a span of at least 2-7/8". That would work really well for this coupler. When it comes to the overall measurements, if we take a look at the overall length measuring from edge to edge, very back to very front, that's going to give us a measurement of about 19-1/4" long. Here at the back, if we take a measurement of the width, again it's designed for 32-degree A-frame trailers. That internal part is going to measure about 9-7/16" wide. That's going to do it for today's look at the Demco 32-Degree A-Frame Trailer Coupler.

  • Replacement Coupler for 2013 Continental Enclosed Cargo Trailer
    The vast majority of A-frame trailers have a 50 degree A-frame which is what the Demco trailer coupler # DM15337-97 fits. This is a weld-on application and welding should be performed by a qualified professional welder. The jack hole accepts a jack that has an outer tube diameter of 2-1/4 inches so compare that to the diameter of your jack. You know how in an auto parts store there will be the large books that list out all the parts for all the vehicles. Unfortunately there isn't anything...

  • Recommended 2-5/16 Coupler To Replace 2 Coupler On 2019 Winnebago Minnie 170K Travel Trailer
    I found a few pictures of the coupler on your 2019 Winnebago Minnie 170k Travel Trailer and you currently have an A-frame coupler. The most likely replacement option is the Demco 50-Degree A-Frame Trailer Coupler w/ Jack Hole # DM13205-95 which is for trailer frames that have the standard 50 degree frame and requires a 2-5/16" hitch ball. The 50 degree A-Frame is the standard but it wouldn't hurt to confirm that the 50-Degree A-Frame is in fact what your trailer uses. The Demco # DM13205-95...
