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 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.

  • Can the Demco 32-Degree A-Frame Trailer Coupler Be Bolted On
    The Demco 32-Degree A-Frame Trailer Coupler part # DM15633-81 must be welded per the manufacturer. I'm sure you could drill holes and attach the coupler that way but we can't recommend this. The weight capacity would be severely compromised if not welded. The location of the holes and size are all crucial factors that require extensive testing for bolt-on applications which we cannot provide for the above.

  • Recommended 2-5/16" A-Frame Coupler w/ Ez-Latch and 9-7/16" Width
    The Ez-latch a-frame coupler we have that will accommodate your trailer's tongue is a little longer than your measurements. It is the Demco 32-Degree A-Frame Trailer Coupler w/ Jack Hole item # DM15633-81. This has the requested Ez-latch and fits a 2-5/16" ball.

  • Options If You Have an Unidentified Coupler That Needs a Latch Repair Kit
    There is not a universal latch repair kit. You will need to match the correct latch repair kit to the correct coupler, you cannot use another brand latch repair kit with a different brand coupler. Typically the coupler information is engraved on the coupler. If you are unable to find the coupler information, you will need to replace the coupler. For that you can use a coupler like the Demco 32-Degree A-Frame Trailer Coupler w/ Jack Hole # DM15633-81. This coupler has an eZ latch style...

  • Replacement Parts or Coupler for UFP CA-50 A-Frame Trailer Coupler
    UFP was bought out by Dexter Axle a number of years ago and they've been phasing out those parts for a while now so I recommend swapping out your a-frame coupler to one that is currently being manufactured so if you need to replace anything in the future it will be easier to do so. For your application I recommend checking out the Demco 32-Degree A-Frame Trailer Coupler which comes in Black # DM15633-81 or Red # DM15633-97 and is rated for 21K lbs. This has the smaller 32-Degree A-Frame...

  • How Much Play Between Demco eZ Latch Trailer Coupler and 2-5/16 Inch Trailer Ball
    According to the good folks at Demco, you can expect to have as much as 3/4 of an inch of vertical play in a 2-5/16 inch coupler like the Demco # DM15633-81 without having an issue. This is necessary, otherwise you could have problems when trying to hitch up on uneven ground. If you're seeing much horizontal play, that would indicate a problem.

  • 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...

  • How to Measure Trailer Frame Angle for Coupler
    You'd just have to physically go out to your trailer and measure the angle. So to do this, you'd need to get a protractor or something similar and place it on the edge of the inside on one side of the trailer frame, and check to see if the other inside edge of the frame is parallel with the 50 degree line on the protractor. 50 degrees is the standard angle for trailer frames, so that's why we recommend you start there. If you do happen to have a 32 degree frame then # DM15633-81 will...

  • A-Frame Coupler with Smaller than 50 Degree Angle
    The standard a-frame coupler degree is 50 degrees but we do have a 32 degree coupler with the part # DM15633-81 but the rear width of it is 9-7/16 inches.

  • 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...
