Video Transcript for Review of Bulldog A-Frame Trailer Coupler - Standard Coupler - BD64FR

Michael: Hi there, I'm Michael with etrailer.com. Today we're going to take a quick look at the Bulldog Collar Lock Coupler with high profile latch. This is a heavy duty coupler, that's going to be ideal for your utility, livestock, cargo, or construction trailers. It does have a weld on 50 degree A frame connection there, so if you've got a 50 degree A frame trailer, this is going to work great for you, you just welded in place and it will give you that connection so that you can pull it.It does have a 15,000 pound weight capacity. So it should do a good job for you pulling those trailers. It has a hinge socket, the ball socket here.

So when we pull back on our collar lock lever, it's going to pop out, make it easy to get connected to that 2-5/16 inch hitch ball. Then when we're ready to reconnect, we just push that in, pull the collar back, pull the latch back, which will release the collar forward. That will lock it in place. So we're going to have a continuously tight fit, which is going to make sure that we're not coming loose. We're also going to have that visual indication to know that everything is lined up properly, it's all in place.So that's the nice part of that collar lock, just automatically pulls back to release and then closes when everything is connected.

Our high profile latch is going to be very easy to manipulate, even if we've got thick work gloves, just simply pull up on that, and then back. It does have a 1/4 inch hole right here. So they've included a pin, but if you want, you could substitute like a padlock or something to make sure you have extra security for your trailer.This whole thing is a high strength, steel construction. So it's going to be very durable, should hold up well to the use and abuse that your trailer receives. We do have a built in jack attachment here.

This whole opening is right at 2-1/2 of an inch in diameter. So it's going to be a great place to mount your round 2-1/2 inch utility jack. Our overall length as you can see it kind of tapers back here and expands down. But if I measure from the front piece to the back here at the top, it's right about 16-3/4 of an inch. If I we're to measure from the front to this bottom edge here, I'd call that closer to about 18-3/4 of an inch.So it's going to be a nice option if you are needing a coupler for your A frame trailer.

This does come with a five year limited warranty from Bulldog. So if you're in the market for a trailer coupler, I think this is going to do a good job for you. That spring loaded latch, I think is a nice option to make it easier, give you a little bit wider ball opening so that it's easier to get hooked up to your ball when you're connecting. And overall, I think it's just going to do a good job for your A frame trailer. So that's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

Review from a similar Collar-Lok Coupler in A-Frame Trailer Coupler


Five star service from etrailer, and maybe a two or three-star product from Bulldog. Aside from the rust and the fact that the collar is so stiff that it can't be operated by hand, the fabrication on the steel attachment plate is poor. The holes for the tongue jack are punched out, twice in some cases, resulting in an enlarged hole, but there are no threads for the tongue jack so you'll have to fumble around and use nuts underneath. The vertical angles on the steel are wrong, so it will splay out at the bottom and won't fit tightly to the A-frame and you will need to shim it out. The interior of the casting is full of weld spatter that will chafe the tow ball. I bought the less-expensive Ram sleeve-lock coupler under a Curt label and the fabrication is much better, having none of the problems the BullDog did. etrailer kindly sent me an RMA to return the BullDog.

We hate to see rust and other complications when it comes to the products that we sell. I have sent this information over to our customer service team for them to contact you.

The Bulldog coupler is SO MUCH easier to hitch up and disengage than my previous coupler which required several back and forth movements of my tow vehicle to engage/disengage the hitch ball.

Used it on a gravity wagon we haul cow feed from the feed mill. Welded right up to the trailer tongue and makes the trailer pull better than the old pin hitch.

Review from a similar Collar-Lok Coupler in A-Frame Trailer Coupler


Really fast shipping, install only took 15 min, and much more solid than the original coupler on the trailer that used two long bolts (which wore and caused the holes to get oblong making the connection to the trailer sloppy), as compared to the four bolts provided with the new coupler.

Review from a similar Collar-Lok Coupler in A-Frame Trailer Coupler


I bought this old really cheap to rebuild. One of the parts that had to be replaced was the hitch, I towed it home with my fingers crossed. I googled trailer hitch, trailer and etrailer was one of the sites that was suggested. I had to find a hitch that fit the 3 1/2" pipe that was the tongue, voila there it was to my amazement. I ordered it right then, 4 days later it was delivered yesterday. Today I mounted it, it was an easy installation and I am really pleased with the hitch and install. My fears of losing a trailer are now history, tomorrow it gets tested with 1 1/2 yards of gravel for the slab for my new. shop

A great product. The original crappy hitch on our new trailer was always a real pain to unhitch. Typically would have to keep the trailer wheels chocked and let the tow vehicle (no brakes and in neutral) roll forward or back freely while raising the tongue - only then would the ball be released from the ball socket. Not good when on a slope. A few times we actually had to pull out the 5/8" ball mount pin and drive forward and let the ball mount slide out of the receiver. No issues at all with the Bulldog hitch. And it's nice to have the positive and easy-to-verify clam-shell hitch mechanism instead of the sliding yoke lock of the original hitch. $200 bucks to have the old hitch torched and ground off and the Bulldog welded on. Money and time well spent.

Solid coupler a good company. The coupler doesn’t have any mechanism to assist in sliding the collar back but I welded on to nubs to pull it back with. I wanted several Master disk padlocks keyed alike but Etrailer could not get those for me so I went with a different online trailer co. that offered a six pack of them at a good price.

The collar hitch was put on my home made trailer and we use it 2-3 times a week. It is smooth working and easy to hook up. Thanx

Works great. Welded it on and was ready to go. Have ordered from etrailer before, and just like every time before my parts arrived very promptly and have never had any complaints with service. Will definitely be using etrailer again.

Review from a similar Collar-Lok Coupler in A-Frame Trailer Coupler


After purchasing a trailer that came with a Collar-Lok coupler standard, we decided to swap out more of our standard couplers over to the this style. So far this product has held up very well. The only downside is the finish/coating is a bit cheap and it started showing corrosion within a few weeks.


Comments
What I recommend is touching up the coupler with a rust resistant spray to help prevent rust.

Review from a similar Collar-Lok Coupler in A-Frame Trailer Coupler


I have a 2003 Jeep Liberty CRD. The spare tyre of the Liberty means the standard tow hitch is on a long bar to clear the spare tyre. I wanted a low profile coupling so I could bring the hitch point in closer to the rear axle to improve the towing characteristics with a 5000 lb trailer. One photo shows my old set-up and the other with the Bulldog. This coupling was ideal.

Great site. This is the second time that I have purchased items from etrailer. Your web page is easy to use and I like the product videos. The trailer couplerI bought was very good and fit properly.

Review from a similar Collar-Lok Coupler in A-Frame Trailer Coupler


LOVE this Bulldog hitch! I welded it to my new custom built motorcycle trailer and I will never go back to the other kind again. So much easier to get a positive connection. I also like the integrated lock hole in the latch. It's definitely worth the money.

Review from a similar Collar-Lok Coupler in A-Frame Trailer Coupler


I changed out the conventional ball hitch on a dump trailer to a bulldog style hitch. There were issues ensuring the original hitch was on the ball correctly. The Bulldog hitch will eliminate that potential problem. Installation was easy. Took about 10 minutes to get the old hitch off and the new one on. The only improvement that I would suggest is to have the lever to retract the collar as the lighter Bulldog hitches do. This one simply has a sliding collar that must be forced back by hand. I always use my foot on the hitches with the lever. But this is a Bulldog issue and not an etrailer issue. etrailer service was outstanding.
