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..

This was to replace a damaged part. Fit perfectly!

I have no idea who is packaging these, but they have no idea what they are doing. These packages with 4 jacks and a coupler in it look like they've been ran over by a truck. The coupler was missing.

It really sounds like the boxes went through a lot. I will have our Customer Service team reach out so that we can have this taken care of for you.

Perfect fit thanks to Amy

I have be buying my trailer parts from etrailer for the last 5 trailers
and I'm very pleast with the secvice and products



by:

Product was perfect for what I needed. Great quality.



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.



by:

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.

by:

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.



by:

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.



by:

Exactly what I wanted and needed



by:

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.



by:

just what I needed to fix my trailer



by:

The product was exactly as described. The fit and function are excellent, the price was good and so far the hitch has worked perfectly.



by:

Easy install for updating trailer. Welded right on and works great!

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!



by:

i purchased 3 A-couplers. I was very pleased with the transaction as a whole. The shipping was "free"! How can you not like that's? Would reccomend and encourage others to purchase etrailer products!

A happy Customer,
Gary H.



by:

I dealt with Chrystal; very helpful and professional. The trailer parts arrived promptly and in good condition. I would buy from etrailer again. Today I ordered steel and will begin building a 5X8 utility trailer.



by:

Good product



by:

Work great and fast shipping
I will
come back if I need more trailer parts.



by:

Great stuff to work with. Pallet racks and etrailer parts



by:

The coupler was very nice! We love you prices. There was fast shipping. Will buy from you again!



by:

Quality All around! Welded up beautifully on my trailer. ????



by:

Have used the trailer on 3 road trips between San Jose Ca and Reno NV over the path year and have no complaints.



by:

Service was excellent throughout product order process. Product was high quality, fit perfectly for welding and was priced lower than comparable brands.



by:

Solid and well crafted. A much better choice than sanding and repainting the old coupler. Thanks e-trailer!



by:

just what i expected. welded it on the tongue. works fine.

  • Replacement Weld-On Coupler For A-Frame Trailer
    The A-Frame Coupler, part # CA5100B is a weld-on coupler that will fit a 2 inch trailer ball. This coupler has a 5,000 lb weight capacity, and also features a 2-1/4 inch diameter hole for a jack to be mounted. I have attached a photo of this coupler with some dimensions noted you can check out. And I have attached a link to a product review video for this coupler.

  • 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...

  • Replacement Coupler for Pro Series A-Frame Coupler
    We have verified with the manufacturer previously that there are no repair kits for the Pro Series A-Frame Trailer Coupler with Trigger Latch PSE338050303, so the if you latch is busted that does mean you'll need to get a new coupler. Thankfully these aren't terribly pricy, and if you want an option for a similar coupler that does have a replacement latch, I recommend the A-Frame Coupler with Black Paint Finish # CA5100B. This coupler has the same 5,000 lb weight capacity and couples...

  • 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 # TJA-5000S-B 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...

  • 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.

  • 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.

  • Coupler Replacement for Damaged Atwood A-Frame Coupler
    Atwood is no longer in the coupler business so we can't get you the repair kit you are in need of. The best solution we can offer is a similar a-frame coupler that fits a 2 inch ball like the etrailer # CA5100B.

  • 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.

  • 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.

  • 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.

  • Replacement for Shelby 5107 A-Frame Trailer Coupler
    Based on my research the Shelby 5107 coupler looks to be an A-frame coupler that accepts a 2" ball, though I was unable to find the weight capacity as this seems to be an older coupler. For a replacement coupler there are a couple different options, depending on the weight capacity you require. These are bolt-on A-frame couplers that accept a 2" ball: - 5,000 lbs: A-Frame Coupler with Black Paint Finish # CA5100B - 7,000 lbs: Sleeve-Lock A-Frame Trailer Coupler - Flip Latch # CA-5196-B

  • Replacement Trailer Coupler Repair Kits for 2-Inch Couplers
    Coupler Repair Kit # CA-5100-RK includes all parts needed to rebuild an etrailer brand or Ram brand 5K-rated 2-inch ball coupler with a trigger latch. 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...

  • 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....

  • 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.

  • Availability Of Repair Kit For A Fulton 5,000 lb 2" A-Frame Coupler
    Hello Jason. Unfortunately we do not offer a repair kit specifically for the Fulton 5,000 lb 2" A-frame couplers. It is possible that the # CA-5100-RK repair kit would work, since the Ram models are quite similar to the Fulton. We have never tested this ourselves though, so I really can't say if it will or will not work. If your coupler is in need of repair, I would have to recommend replacing the coupler entirely with a new one. Something like part # CA5100B is a very similar 5,000 lb...

  • 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.

  • 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.

  • 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,...

  • 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.

  • 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. 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.

  • Coupler for A-Frame Trailer
    The type of coupler you have is actually pretty common as it's an a-frame style like the part # CA5100B. This does not have holes in it but we don't have an option that does so you could either weld this on or drill holes to use the current holes you have.

  • A-Frame Coupler and Trailer Jack Replacement for Shelby 5101 Trailer
    I looked up your Shelby 5101 trailer and it is an a-frame trailer that has a weld on a-frame coupler that has a jack mounting hole built into it. So since the coupler uses a non-standard bolt pattern for the jack I'd recommend replacing the coupler and jack together like with the # CA5100B for a coupler and then for a jack the # TJA-5000S-B would be a great option.
