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

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.


Demco Coupler Cutaway

Unlike most couplers, which have a pin hole through the handle latch, the eZ-Latch coupler features a hole through 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 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 Review of Demco Straight Tongue Trailer Coupler - Standard Coupler - DM15931-95

Today we're going to take a look at the Demco EZ-Latch Channel Tongue Trailer Coupler for the two and 5/16 diameter hitch ball. This one has a 21,000 pound weight capacity. Now this is a straight tongue coupler, it's made of a sturdy steel construction, it has a nice zinc finish on it. Offers corrosion resistance. It does meet the 200 hour salt spray rating, and it is a channel tongue coupler that will let you hook up your trailer to your tow vehicle, provides the connection point right here for your two and 5/16 diameter hitch ball. Now what's unique about this one, it uses the EZ latch coupler mechanism right here.

This ensures fast, simple, secure hookup and disconnect. Basically it will let you hook up when the latch is in the closed position like it is now, you just drop the coupler over the hitch ball, the latch will snap it into place and secure it.And I'm going to demonstrate that here's a two and 5/16 diameter hitch ball that it would fit on. So you can see if I just take that coupler, drop it on the top and you push down on it. You can see it snaps right into place. This has all stayed closed, and it snaps and secures it to the hitch ball.

And then to release it, just pull up all the way on the latch and it slides right off. Simple as that. There's no pin needed or safety clip to hold it into place. And again, just to show you, we close it, drop it on there, snaps right into place. The latch itself is a corrosion proof polymer nylon resin composite latch handle.

It's very durable and impact resistant. Now to lock this, you can lock this to your hitch ball so nobody takes it. Basically this hole right here is a 5/16 diameter hole. It goes all the way through. You can put a coupler lock pin lock all the way through there as long as you got to make sure it's a 5/16 diameter coupler lock.And it does have a minimum span width, from here to here is three inches.

You can put that lock pin through there, put the lock on this side and it'll lock it so nobody would take it. And again, this is a bolt on installation. You can notice on the side here it has the four bolt holes. Now the installation hardware to install this is not included. This part is made in the USA. Mounting, this is designed to mount to a three inch wide straight channel tongue. So you can see if I measure the inside to inside width on this is three inches. Again, the hitch ball, it's designed to fit onto is a two and 5/16 diameter hitch ball. And the weight capacity on this is 21,000 pounds. But that should do it for the review on the Demco EZ-Latch Channel Tongue Trailer Coupler for a two and 5/16 diameter hitch ball.

See what our Experts say about this Demco Straight Tongue Trailer Coupler

  • Availability for Safety Pin for Trailer Coupler
    Many couplers like the # DM15945 do not come with a safety pin. This likely cuts cost out of the product and allows you to use an existing safety pin if you have one, choose your own, or add a lock instead. This particular coupler has a 5/16" diameter hole and requires a 2-1/2" span so you could use a coupler pin like the # 37201051. I'm not sure which coupler you have. If it is the MC51923 you mentioned that doesn't bring up any product here at etrailer, or anywhere else on the internet...

  • Demco Channel Tounge Coupler Length
    According to Demco the Channel Tongue Trailer Coupler # DM15931-95 is 13.7" long. Don't forget a etrailer Brake Coupler Lock # e98888. As this coupler has an oversized latch to make unlatching easier but does require a special size lock to keep your trailer secured.

  • Comparing Demco Channel Tongue Trailer Couplers # DM16080-95 & # DM15931-95
    The only difference in the Demco Channel Tongue Trailer Couplers # DM16080-95 and # DM15931-95 is going to be the bolt pattern. One will have the 5-Bolt hole pattern and the other is going to have 4-Bolt holes. I have included images below showing the measurements for each of these bolt patterns to compare with what you have on your trailer. The etrailer Surge Brake Coupler Lock # e98888 will allow you to secure the coupler while attached to your vehicle. We also have a Pin # 37201211...

  • Replacement Trailer Coupler For Replacing Titan Model 6 Surge Brake With Electric Over Hydraulic
    For replacing your Titan Model 6 # T4747220 I recommend the Demco Channel Tongue Trailer Coupler # DM15931-95. They will share the same 3" and 2" bolt bolt hole separation that you are currently using on your trailer. You will need a etrailer Coupler Lock # e98888 if you wish to lock this coupler as it requires a 3" minimum span.

  • Hitch Pin/Lock Needed For Demco Channel Tongue Trailer Coupler # DM15931-95
    For the Demco Channel Tongue Trailer Coupler # DM15931-95 you will need the Coupler Pin # 37201281 to ensure the hitch ball does not come unlatched while towing. You can also use the Lock # e98888 for additional security. The Pin # 37201244 you found only has a usable length of 2-9/16" and you need a minimum of 3" to fit your coupler. Also with the coupler pin opening of 5/16" you will not want to use a 5/16" pin as the pin is more likely to get stuck due to corrosion.

  • Is There 36,000 lb Coupler For 36,000 lb Bulletproof Hitches Ball Mount
    I believe by 36,000 lb ball you are referring to the 36,000 lb rated 2-5/16" ball that is part of the BulletProof Hitches ball mounts such as the 2-Ball Mount for 3" Hitch - 9-1/4" Drop, 8-1/4" Rise # ED308 or 2-Ball Mount for 2-1/2" Hitch - 7-1/4" Drop, 7" Rise # ED256. There is not a 36k coupler to go along with this that we offer, the highest rated coupler we can provide is 21,000 lbs, such as the Demco Channel Tongue Trailer Coupler # DM15931-95 or Demco 32-Degree A-Frame Trailer Coupler...
