Video Transcript for etrailer A-Frame Trailer Coupler - Standard Coupler - CA5100B Review

Today we're going to take a look at the A frame trigger latch coupler with the black powder coat finish, for a two inch hitch ball. This A frame coupler will let you hook up your trailer to you tow vehicle, provide you a connection point for the hitch ball. Now this uses a trigger latch design, which allows for safe and easy coupling and uncoupling of your trailer to the hitch ball. Basically you just put your finger on the trigger latch right here, pull up on it, then pull up on the latch itself, and that'll open up the ball socket underneath. Basically the way to install it, I happen to pull here a two inch diameter hitch ball. Basically you just drop it with it in the open position, you drop the coupler right on to the hitch ball, and then just fully completely close your trigger latch. As you do that, the trigger latch will actually lock into place right there, and then you're all attached, ready to go.

If you want to, the hole right here will allow for a coupler lock to go through, for extra security. To release it, just pull up on the trigger latch, lift the latch up and it'll release it from the hitch ball. This is made of a sturdy steel construction, has a nice black powder coat finish, to provide corrosion resistance. It is an A frame design, so it is designed to mount to a fifty degree trailer tongues. It is a weld-on installation, it is also SAEJ684 certified. If you notice the hole here in the back, that is your built-in jack attachment point, allows for quick, easy mounting of a round utility jack.

The hole diamter right there, I'll put a measurement on it for you, it's going to be right at two and a quarter inches. You also notice there's three threaded holes right here for installation of the jack, so it will require three, three eighths by sixteen inch sized bolts for installing your jack to this. Again, this is designed to fit a ball size of two inches, total weight capacity on it is five thousand pounds, tongue weight capacity is seven hundred pounds. The pinhole diameter right here, which is designed for the coupler lock is five sixteenths of an inch, and just to give you some overall dimensions, the width from edge to edge is going to be right at ten inches. The length from this end to this end is going to be right at thirteen and three eighths inches long. That should do it for the review of the A frame, trigger latch coupler, with the black powder coat finish, for the two inch hitch ball..

The coupler that came with my trailer was slightly misshapen, causing a back and forth jerking motion within the tow vehicle. We ground off the old one and welded on this new one - problem solved! I especially like that the mechanism on this coupler is both adjustable and easy to hook up and unhook. 494799

It might be possible to give 5 stars but after purchasing all the products about a year ago, my little fiberglass trailer is not even close to being ready. All the lighting is hooked up and they all seem to work, so that's a good thing. The other products that I purchased have not been installed yet. I would like to mention how pleased I am with e-trailer videos showing everyone how their products look and how they're used. Keep it up, I am a happy customer. Vic 366252

I purchased items to build 2 complete trailers, including axles, springs, hitches, lights and wiring etc. The service was outstanding! The items were delivered on time and correctly. I was also quite surprised with their very good pricing. In total, my items weighed in excess of 200 lbs., and yet I spent less having these things shipped to California from this company than I would have at my local area stores. Without doubt, I will use this company again when I need these types of products. 336197

Products came sooner than expected package was in good shape and order was right even though I ordered many items 337333



- CA5100B
by:

Only intermittant use, but coupler still working well. Just one word of advice, if you are going to use it on a trailer that is going to be pulled by an ATV, the location of the hole for the trailer jack ends up making the trailer jack too close to the back of the ATV, where I can't put the coupler on the ball on the ATV. I was able to solve this by getting an extension piece (basically part C45006) for my ATV to move the trailer back a bit from the back of the ATV. This would be a problem with any A-frame coupler though. 316418

I just used the handle and the internal parts but the price was not bad and the shipping was not that expensive. I was quoted $85.00 and Shipping and headlining from the local RV place at $100.00. After paying $18.95 and shipping of around $9.00. Now I can go on my next camping adventure after saving $72.00. I even called e-trailer and the lady was very helpful and very friendly. In the future I will be doing more business with e-trailer. Thanks. 268838

Comments

A year in, they are all working well. They all went into an older trailer that needed a lot of TLC. I am happy with the quality of the parts and I have used the trailer quite a bit in the last year. The brakes are what I am most pleased with. Easy install and work very well. Thank you!

Do you have a question about this A-Frame Trailer Coupler?


  • Replacement for Shelby 5101 Coupler
  • Based on my research the Shelby 5101 is an A-frame coupler with a 2" ball and 5,000 lb capacity. We have exactly that with the A-Frame Coupler # CA5100B, which has a trigger latch and has a black paint finish. The same coupler is available with a simple zinc finish, part # CA-5100-Z. I've added links to video reviews of both couplers for you to take a look at.

  • Best Replacement for Shelby 5101 A-Frame Coupler
  • There are no repair kits for Shelby couplers because the company was acquired some time ago; your best option at this point would be to get a new coupler. The Shelby 5101 is an A-frame coupler with a 2" ball and 5,000 lb capacity. We have exactly that with the A-Frame Coupler # CA5100B, which has a trigger latch and has a black paint finish. The same coupler is available with a simple zinc finish, part # CA-5100-Z.

  • Wedge Style Latches Vs. Trigger Latches on A-Frame Couplers
  • The main difference between the wedge style latches and the trigger latches is in the capacity of the coupler. The lighter capacity couplers will use a trigger latch, whereas the higher capacity couplers will use wedge latches. For example, the Bulldog Heavy-Duty Cast Head Coupler w/ Wedge Latch # BD44125W0317 that you referenced uses a wedge latch and has a capacity of 12,500 lbs. An A-Frame Coupler # CA5100B uses a trigger latch and has a capacity of 5,000 lbs. Either style will...

  • Recommended A-Frame Jack And A-Frame Coupler For Custom Boat Trailer
  • We don't have any A-frame jacks with the outer tube measurement of 1-3/4 inches. All of our standard jacks have a minimum of a 2 inch inner tube and 2-1/4 inch outer tube diameter like you find on the Round A-Frame Trailer Jack - Topwind - 14-3/4" Travel - 2,000 lbs, # TJA-2002-B. These jacks come in a wide variety of capacities and with different foot or wheel options. My recommendation because you do have the mounting flange measurements is to get the proper jack for your capacity...

  • Shelby 5101 Coupler Replacement
  • There are no repair kits available for the discontinued Shelby 5101 coupler; your best option is to replace the coupler.

  • Trailer Tongue A-Frame Angle Compatible with CA5100B A-Frame Coupler
  • Because they consider it proprietary information, the manufacturer will not provide a build sheet or detailed drawing of the # CA5100B. I believe you're needing the angle of the A-frame trailer tongue which would be equal to the angle of the two sides of the coupler which is 50 degrees, as shown in the photo I've provided.

  • Trailer Ball is Loose in Coupler
  • Some couplers can be adjusted so that the wedge will grab the trailer ball more tightly, but since the coupler you're using has no adjustment available, I'd first confirm that you are using the correct trailer ball size for your coupler. The required ball size for the coupler should be stamped into the metal on the top of the coupler. If you were using a 1-7/8 trailer ball with a coupler designed for a 2 inch ball, it would explain why the ball is loose in the coupler. If this is the case,...

  • What Are The Dimensions of Redline A-Frame Trailer Coupler # CA5100B
  • I walked out to our warehouse and pulled the Redline A-Frame Trailer Coupler # CA5100B. At the widest point inside the coupler measured approximately 9-1/4 inches, the narrowest approximately 2 inches and 8 inches between those points. Check out the picture that I have attached that I added dimensions to for you to view. This coupler is a weld-on application for A-frame trailers, works with 2 inch hitch balls and has a 5,000 lb capacity. Also linked is an FAQ on trailer couplers.

It consists of all components other than the housing. If you have one of these models - # CA5100B, # CA-5100-Z or CA-5100-BLB - then this is the correct rebuild kit. If you have another brand or model of coupler on your trailer you can refer to the linked page that displays all such kits for many brands of coupler. The Big Tex website...

  • Installation Information for Redline A-Frame Trailer Coupler # CA5100B
  • When installing a trailer coupler like the Etrailer A-Frame Trailer Coupler, part # CA5100B, you want the coupler right up against the edge of the trailer frame. This coupler is a weld-on coupler for A-frame trailers. I would recommend having a qualified welder or trailer professional install the coupler. I have linked an FAQ on trailer couplers and all of the A-Frame trailer couplers we have available.

  • Availability of an A-Frame Coupler that will Fit a 1-7/8 Inch Hitch Ball
  • We don't offer any A-Frame style couplers that are compatible with a 1-7/8 inch trailer ball. The best bet if you're wanting to use a coupler like the # CA5100B you referenced would be to remove the 1-7/8 inch trailer ball you currently have and switch to a 2 inch ball. You'll want to make sure that the 2 inch ball you choose has a shank diameter that's compatible with your existing ball mount. 2 inch trailer balls are available with shanks measuring 5/8, 3/4, 1 or 1-1/4 inch diameter....

  • Replacement Coupler Recommendation for Fulton 33305
  • It doesn't look like we have an exact replacement coupler latch kit available for your trailer coupler. Your best option would be to replace your coupler with something like the # CA5100B which is also a A-frame coupler designed for a 2 inch ball but it has a 10k capacity.

  • Replacement Jack and Coupler for a 1955 Traveleze Trailer
  • Sounds like you are looking for a trailer jack. I looked up some pictures of your 1955 Traveleze and it is built on an A-frame so for an A-frame jack something like the part # BD1700100317 would work great. I attached a review video for more info for you to check out as well. Or it is possible that you are looking for a coupler repair kit. We offer several repair kits, but it will depend on what coupler you have on your trailer to know what would work best. See attached link to see them...

  • Tongue Angle of the A-Frame Coupler Part # CA5100B
  • The A-Frame Coupler with Black Paint Finish part # CA5100B works with a-frame trailers that have a tongue which comes together at a 50 degree angle (Industry Standard). This coupler will attach to a 2" hitch ball and has a 2-1/4" diameter pilot hole for trailer jacks. I have attached a photo of the coupler angle for you as well.

  • Replacement for Pro Series A-Frame Trailer Coupler with Broken Latch
  • If the trigger broke on your Pro Series A-Frame Trailer Coupler # PSE338050303 then you would need to replace the whole unit. I reached out to my contact at Pro Series who said that they unfortunately do not have carry any replacement parts for this coupler. A similar option would be the A-Frame Coupler # CA5100B which also has a 5,000 lb weight capacity and is compatible with 2" hitch balls. The latch system is a little different but because of this there is a replacement part # CA-5100-RK...

  • Trailer Coupler Lock Recommendation When MasterLock and DeadBolt are Too Long
  • If you want a bar and key style lock like the deadbolt, the smallest span that will still fit your coupler is 2 inches. So you will have 3/4 inches left over. Since you have already tried MasterLock and Deadbolt, maybe you would be interested in a different type of lock. I have included a link to our coupler lock main page for you to view. You might find something like the Gorilla Guard, # 63227, will give you a better fit.

  • A-Frame Coupler For 2015 H&H Enclosed Trailer
  • When looking up the specs for the H&H CA Series Flat Top Single Axle Cargo it said that this trailer uses a 2” A-frame coupler. The A-Frame Coupler Item # CA5100B will work with your trailer. It has a 2-1/4" hole diameter for jack: It requires (3) 3/8"-16 bolts for installation (not included). It will need to be welded on. If you need a bolt on coupler # DM14793-81 will work also. I have attached all of our 2" A-Frame Couplers to this page.

  • Recommended Trailer Coupler Lock for A-Frame with Trigger Latch
  • Do you have a photo of your trailer coupler? If it looks like the A-Frame Coupler part # CA5100B then yes, the Master Lock Heavy-Duty Coupler and Latch Lock Combo part # 3784DAT should work for you as that is what it is primarily designed to fit. I have attached a review video on a straight trailer coupler but it will also work on a-frame trailer couplers as well.
