Video Transcript for etrailer A-Frame Trailer Coupler - Standard Coupler - CA5400 Review

Today we're going to take a look at the A-frame, thumb latch trailer coupler, with an oily finish for the two and five sixteenths hitch ball. This A frame coupler will let you hook up your trailer to your tow vehicle, provides the connection point right here for the hitch ball. It is a thumb latch design, which makes it very easy to clamp around the ball. Basically to open it up you just pull the latch up, slide it back towards the trailer, and it'll open the ball socket ready for the hitch ball. Then to close it you slide the latch forward and it'll close around the ball. I did happen to pull a two and five sixteenths diameter ball, just to show you how this connects. Again, as we mentioned, to open it just lift up and slide it back, that'll open up the ball socket, goes over the hitch ball.

You just push it forward, you can see that it'll lock right into place. To remove it same way, just release it like that. Now this is made of a sturdy steel construction, this one does have an oily finish to provide corrosion resistance, as you can look at my hand, you can see how the finish is very oily. It is an A frame design, as you can see right here, it mounts to a fifty degree trailer tong. It is a weld-on installation.

This SAEJ684 certified, if you notice on the very back here, the round hole with the three holes, this is a built in jack attachment point. Allows for quick, easy mounting of a round utility jack. The diameter of the hole that the jack goes through, put a measurement on that, it's going to be right at two and a quarter inches. If you notice it does have three threaded holes for installation of the jack. It does require three, three eights by sixteen bolts for installing the jack. The ball size again that it fits on is a two and five sixteenths diameter.

Total weight capacity is fourteen thousand pounds, tongue weight capacity is twenty-one hundred pounds. There is a pinhole right here, that if you do want extra security to lock it, you get a coupler lock, it does have a five sixteenths diameter pinhole diameter. Give you a few overall dimensions, we're going to measure the width, from this edge to this edge. If I put a tape measure on it, it's going to be right at ten and seven eighths inches wide, and in the overall length, from this end to this very end right here. If you can see, is going to be right at twelve and seven eights inches long. That should do it for the review on the A frame, thumb latched trailer coupler with the oily finish, for a two and five sixteenths hitch ball..

A-Frame Coupler with Oily Finish - 2-5/16" Ball - 14,000 lbs - CA5400

Average Customer Rating:  4.7 out of 5 stars   (53 Customer Reviews)

Heavy-duty A-frame coupler features sturdy steel construction, an oily finish and an easy-to-use latch for secure hookup.


Tongue is as advertised and size seems to match the trailer perfectly. Haven't had a chance to have it welded yet but don't anticipate any problems. It definitely has an oily finish. Wear gloves when handling if you don't want it all over your fingers.

After a year the trailer coupler is working perfectly. I recently bought another trailer that Im considering changing the coupler on and buying another one.
Jeffrey W - 06/22/2016


We just got this installed on our 12,000lb (GVWR) car hauler, and it seems quite adequate for the job.

Everything seems to work just fine. We have used this 12,000 lb GVWR trailer to haul cars, trucks, and other sorts of cargo over the past year, and the frame coupler has been as strong as it needed to be. We are very satisfied with this product
Phil D - 01/10/2021


New hitch arrived on time and at a great price. E Trailer helped keep down time to a minimum

Still works and looks like new
Jim B - 07/15/2021


Have used this product before with Etrailers. Price can't be beat. Will purchase with Etrailers in the neat future.


Works! is overkill for the trailer it was installed on but wanted a one ball setup so I could stop changing the ball every time I switched trailers


Product is perfect for this 74 X 120 stucco crew trailer w/7k axle and G rated tires. Very good price and quality. I'll buy again as needed.

After one year, still great service.
George - 01/19/2018


I had a one time need to put a long tongue on trailer to enable me to haul a 60' sail boat hull to the shipyard.

I welded the hitch to a 16' 4" x 5" box beam along with 2" x 2" angles at the angles provided in the Hitch shape. The other ends to the trailer, loaded the boat, and Viola! It all went with only one hitch, the one I bought.

Great help!


The price's at etrailer are great. The trailer Coupler I purchased looks to be better quality than what my trailer was built with. The folks at etrailer are great to do business with, great service,great shipping, as a matter of fact...they even put a rush on my shipping without charging extra for it.....You know I will be back!


Product was great quality. It fit the trailer tongue perfectly. Welded it on and bolted for safety.


The parts I needed were difficult to impossible to find here in the northeast.
You website made it real easy to find what I needed to restore my flatbed trailer.

  • Difference Between Finishes of A-Frame Couplers CA5400 and CA5400-B
    The oily finish of the A-Frame Coupler with Oily Finish # CA5400 that you referenced is designed to fight off corrosion. But it's pretty messy when handling so I'd recommend going with the painted version part # CA-5400-B instead.

  • Replacement For A-Frame Coupler CA5400
    There are no repair kits available for the A-Frame Coupler # CA5400, so the best we can offer is to replace it with the same or, if you don't want the oily finish, the A-Frame Trailer Coupler # CA-5400-B.

  • Replacement A-Frame Coupler That Measures 11 Inches At Widest Point
    The Redline 14K capacity A-Frame Coupler, part # CA5400 you referred to measures 11 inches wide at its widest point, like the A-Frame coupler you showed in the photo you provided (thanks for the photo, by the way.) The # CA5400 is compatible with 2-5/16 inch trailer balls, and would make an excellent replacement for your current corroded A-Frame coupler.

  • What is Angle of Redline A-Frame Coupler, part # CA5400
    Most A-Frame Trailer Couplers have a standard of 50 degrees. I produced a short video for you showing the angle of the etrailer A-Frame Coupler, part # CA5400. I have also linked an FAQ on trailer couplers.

  • Does the etrailer A-Frame Coupler Weld On or Bolt On
    The etrailer A-frame Coupler part # ca5400 is a direct weld-on application. You will weld along the edge of the coupler. I recommend having a qualified welder or trailer professional install the coupler. This coupler works with 2-5/16 inch hitch balls and has a 14,000 lbs capacity. I have linked an FAQ on trailer couplers for you to check out.

  • Availability of an A-Frame Coupler that is 45 Degrees and Not 50 Degrees
    All of the A-frame couplers we carry are for the standard 50 degree A-frames. What you could do, since your A-frame is a lower angle, is have some steel spacers welded on to get to 50 degrees and then use a weld-on coupler. I have linked the weld-on options for you.

  • Can Surge A-Frame Coupler be Replaced with a Fixed Coupler
    From the pictures I found online of your 2000 Jayco Eagle ST it appears your trailer has a standard a-frame style coupler on it so you could replace what you have with a coupler like the part # CA5400 and you'd be set.

  • Determining Year of Manufacture Based on VIN Number
    Your Trailer Vin should be able to give you the year it was manufactured. If your Vin is the 17 digit traditional format post early 1980's, then the 10th digit will give you the ending digit of the year it was manufactured. I've attached a photo to assist with the code. When you say Paris Trailer, all I can find is Paris Custom Trailers or PJ trailers, both of which are located in Paris, Texas. They may be able to assist if you don't have the 17 digit VIN. Your final option would...

  • Registering Trailer With a VIN But No Title
    Since you have VIN number, you will simply need to get a bill of sale since he didn't have a title. The DMV won't have record of the trailer because it hasn't been registered with a title yet. With the VIN and a Bill of Sale, you will be able to get the title you need and get it registered.

  • Difficulty Finding VIN on Old Ranger Trailer
    The VIN on your Ranger might be in a number of possible locations. Typically the number will be found toward the front of the trailer frame, on an inside-facing surface. If you cannot locate the information there, I recommend simply looking up and down the frame along the length of the trailer. If you find that a VIN is simply not present, and you do not have any paperwork with this information, you may be able to have your local state police or highway patrol assign a new one for the trailer.

  • Troubleshooting A-Frame Weld-On Coupler Not Going Over Hitch Ball Smoothly
    There are a few reasons why you might be having some difficulty latching your A-Frame Weld-On Coupler # CA5400. First, I recommend making sure that the coupler is unlatching completely when you are uncoupling from the hitch ball. It's possible that it is unlatching just enough to release from the ball but not all the way, making for a more difficult connection when hooking back up to the tow vehicle. I also recommend making sure that the coupler is free of dirt, debris or corrosion, as...

  • What Is The Angle For The Trailer Tongue For The Coupler # CA-5400-B
    The A-Frame Trailer Coupler - Thumb Latch - Black - 2-5/16" Ball - Weld On - 14,000 lbs # CA-5400-B is designed to fit over the frame of your trailer and sit flat. The angle of the trailer frame to the bottom of the coupler shouldn't change as this is not an underslung coupler. They will be parallel. The angle of the trailer frame side to side is most likely what you are asking and it is the standard 50 degree angle.

  • When Does An A-Frame Coupler Need Replacing?
    An A-Frame trailer coupler like # CA-5400-B is bad and needs replaced if it no longer connects to your trailer hitch ball correctly with its latching mechanism, no longer supports the trailer jack, is not solidly connected to your trailer frame (has cracks), or can't handle the weight capacity it was intended to due to corrosion or impact from an accident.

  • What Trailer Frame Angle Should A-Frame Trailer be Made to To Fit Standard Couplers
    So the standard angle for A-frame trailers where the two beams meet is 50 degrees. So while I can't get you a CAD drawing for the coupler part # CA-5400-B if you are trying to design your trailer to have the correct angle for the A-frame you should make it as close to 50 degrees as you can and standard couplers like this will fit and work well.

  • Is There A Repair Kit Available For The A-Frame Coupler CA-5400-B
    The only option we will have would be a full replacement of the coupler. Unfortunately, there currently is not a repair kit offered for the # CA-5400-B couplers. As this is a weld on coupler, the latch components can be removed from a new one and then installed on your current one.

  • How to Adjust etrailer Weld-On A-Frame 2-5/16-Inch Coupler # CA5400
    The etrailer Weld-On A-Frame 2-5/16-Inch Coupler, part # CA5400, does not have any adjustment screw to enable you to take up the slack in the fit with your hitch ball. This coupler is produced by a stamping process and this type of manufacturing method will have some slight variances from one unit to another. The 1/4-inch play you find is fairly typical. You can test the security of the attachment at the hitch ball by using your trailer jack to lift the nose of the trailer while the coupler...

  • Latch Width and Hole Diameter for Trailer Coupler # CA5400
    I went out to the warehouse and pulled trailer coupler # CA5400 to measure the latch width and its hole diameter. The latch outside width is just over 7/8 of an inch at 0.88 inches. And the hole diameter is just over 5/16 of an inch at 0.32 inches. If you end up needing a lock our lock # e98889 is a good choice. It has a 7/8 inch span and a 1/4 inch diameter pin.

  • Will the Master Lock Trailer Coupler Lock # 377DAT Fit on a 2012 Keystone Cougar Trailer
    I did a little online research and found that Master Lock Trailer Coupler Lock, # 377DAT, should work well on the coupler on your 2012 Keystone Cougar X-Lite 30RLS trailer. I posted a photo of a coupler similar to the one I saw on the same model trailer as yours on the internet for you to check. Compare this coupler to yours so you can be sure this is the style coupler that is on your trailer. If so the # 377DAT coupler lock will work great.
