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 black 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.

  • Help Understanding and Achieving the 21K Weight Capacity of Demco Trailer Coupler # DM14040-81
    First I want to make sure you verify your channel mount for the Demco Trailer Coupler # DM14040-81 has a 21K or larger capacity as often times they are less like the Demco # DM15349-52 which often times people look at and think it is a channel mount like the coupler so it has to be rated the same. The other big hang up most people have is the see the Hardware # DM6166 only being grade 5 instead of grade 8 which should be stronger. The big difference is while grade 8 bolts allow for more...

  • How To Replace Surge Brake Shocks On Demco Actuator On 2004 Heritage Boat Trailer
    Thank you for the image of your setup Steve. I do not know what the manufacturer was thinking when they welded in the Demco Actuator on your boat trailer. With how it was installed there is no way for you to access that rear pin without drilling a hole through the frame. They should have installed either the Disc # DM8205222 or Drum # DM8202232 brake actuator which would sit on top of the A-Frame and allow you to access all components of the hitch. If you decide this is the best way to...

  • Coupler Lock Recommendation for Demco EZ Latch Style Coupler
    The Demco Channel Tongue Trailer Coupler - Zinc - 2-5/16" Ball - 3" Channel - Bolt On - 18K # DM14040-81 has an integrated 5/16 inch pin hole with a 3 inch span for that lockable feature. I recommend using the Trailer Coupler Lock # e98888 which has a 3-3/8 inch span and is 1/4 inch diameter.

  • Recommended Lock For A Demco 2-5/16" EZ Latch Coupler
    You certainly can use the Trimax Coupler lock # TMX47FR with the Demco 2-5/16" Ez latch coupler like the # DM14040-81. The Demco coupler is 2-7/8" wide on the outside so it will undoubtedly fit with the Trimax lock, which is more or less universal. That being said, if you need a lock for the Demco EZ latch, I recommend the InfiniteRule Lock # IR66FR which is made specifically for the 2-5/16" Demco EZ Latch couplers so it will be a perfect fit.

  • Torque Needed For Bolts on Demco Channel Mounted Coupler
    Good question; the bolts in the Hardware Kit for Demco Adjustable Channel Mount Couplers # DM6166 should be torqued to 150 lb-ft during install of a Demco coupler like # DM14040-81 to a bracket like # DM66134.

  • Locking Coupler Pin Capable Of Fitting A Demco eZ-Latch Coupler With 2-5/16 Hitch Ball
    You will need to use the etrailer Coupler Lock # e98888 with your Demco Trailer Coupler # DM14040-81. The InfiniteRule Lock is only for a 2" Demco eZ-Latch coupler. The etrailer lock above is longer to fit your wider coupler.

  • Availability of Demco EZ Latch Couplers for 2 inch Ball that Fits Adjustable Channel
    That part number BC21014 is actually the part number for a Demco coupler decal and not for an actual ball mount. I was able to determine that your coupler uses a 2 inch ball from the sticker though. For a channel mount style Demco EZ latch coupler we have the part # DM14976-52. If you have a different style of coupler I attached a page that has all of the 2 inch Demco couplers we offer.

  • Can Auto Latch of Demco Trailer Coupler # DM14040-81 Be Operated with Pin Lock In Place
    If you had a pin lock inserted in the coupler part # DM14040-81 that you referenced it would not auto-latch onto the hitch ball. The latch portion would not be able to slide up to let the ball pass. If you check out the picture I attached you can see that the pin hole would prevent that.

  • Recommended Lock for Demco DM14040-81 Coupler
    The # BLTL-23 Blaylock coupler lock is compatible with a very specific type of coupler, the CollarLok like our part # BD028499, so it wouldn't be a good fit for a coupler like the Demco # DM14040-81. A lock like the # FA86-0015-316 or a latch type lock such as # 2847DAT would be your best fits.

  • Can Coupler Pin Be Added To Demco Trailer Coupler
    Yes, you can use a coupler pin or safety pin with the Demco Trailer Coupler # DM14040-81. A pin like the # 37201211 will fit the 5/16" pin hole or you can use the etrailer Surge Brake Coupler Lock # e98888 if you want even more security.

  • What to Do If Coupler is Designed to Fit Wider Trailer Channel
    Hey Steve, so I think you maybe worded what you were trying to explain backwards but I know what you are asking about. If the coupler was designed to fit a slightly wider frame channel what is best way to take up the extra room? In that situation we recommending having thin spacers welded to either side of the frame channel. So for a difference of 1/8 inch you'd want to have 1/16 inch spacers welded on either side.

  • Recommended Coupler Lock For A Demco EZ Latch Coupler
    When it comes to a good coupler lock for your Demco Trailer Coupler - Cast - Adjustable Channel - eZ-Latch - Black - 2-5/16 inch Ball - 21K # DM14040-81 I recommend The Fastway Universal Trailer Coupler Lock for 1-7/8 inch, 2 inch and 2-5/16 inch Couplers # FA86-0015-317.

  • Recommended Lock for Demco eZ-Latch Coupler
    To secure your PJ Trailer that's equipped with the Demco eZ-Latch Coupler # DM14040-81 I highly recommend the Fastway Universal Trailer Coupler Lock # FA86-0015-318, which doesn't require a lip on the coupler for a proper connection. This is a heavy-duty lock that uses a ball and shackle to prevent potential thieves from coupling their truck to the trailer and taking off. Its hardened chrome-plated construction will resist corrosion and the bolt-blocked locking system prevents the lock...

  • Wheel Lock Solution for Trailer that Was Stolen that Had Demco Coupler
    That is a super frustrating story. There isn't really a great way to lock the Demco coupler part # DM14040-81 to a trailer but a better option might be a wheel lock like the part # 288-02020 which would at as a theft deterrant. Somebody must have really planned out the theft of that trailer though as they had tools to remove the coupler and seemingly had the same coupler or drug it off by the safety chains.

  • How to Lock Demco 21K Adjustable Channel Trailer Coupler
    The Demco Adjustable Channel Trailer Couplers like the 21K # DM14040-81 use 5/8" diameter bolts for attachment to the adjustable channel, so you could potentially replace them with 5/8" locking pins like etrailer.com # e98881. Please keep in mind though that Demco does state that the standard Grade 5 mounting bolts # PS024202 do need to be used to achieve/maintain the coupler's 21,000 pound weight capacity. With this in mind I don't recommend doing this, as this could potentially lower...

  • Will The Blaylock EZ Coupler Lock Work With A Demco EZ Latch Coupler.
    I have a solution for you. The Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33 will not work with the Demco Trailer Coupler - Cast - Adjustable Channel - eZ-Latch - Black - 2-5/16" Ball - 21K # DM14040-81. You will need a coupler lock like etrailer Surge Brake Coupler Lock - 3-3/8" Span - 1/4" Diameter - Chrome # e98888. This can be used while coupled to a trailer or while off vehicle.
