Video Transcript for Bulldog A-Frame Trailer Coupler - Standard Coupler - BD028499 Review

Today we're going to take a quick look at the Bulldog collar lock coupler with low-profile latch, part number BD028499. Bulldog covers this coupler with a limited 5 year warranty that has a gross trailer weight capacity of 12,500 pounds. It's designed to work with standard 50 degree A frame trailers and it's a well done application so you'll just weld along the edges of the coupler to secure it to your trailer's frame. It has the cut out assembly for a jack where there's the main hole for the body of the jack and three bolt holes spaced apart according to industry standards for mounting the jack to the coupler. Now we're going to go over the coupler's mechanism. There's a collar that has to slide back and this hinged jaw will then be able to open up.

There's a pin in place that stops the collar from moving back accidently. So, we'll remove the pin and then we can operate the jack. We'll grab this lever and pull it, the collar slides back and the jaw pops open. Now, there's a shoulder here on our jaw that holds the collar back so it doesn't close while you're trying to hookup or unhook your trailer. To close the jaw, we can either just hit it closed or push it down while holding the latch and slowly let the collar over it.

We've got a 2-5/16 ball with us so we can show you how it works with an actual ball. The coupler is closed, so we'll grab our latch and open it up and the hinged jaw pops open, fit our ball into place and the coupler closes. Now our ball is secure, but it allows enough movement for it to track behind our tow vehicle. Now we'll just push our latch down and open our collar and the ball comes free. Again, we'll hold the collar back, push the jaw down and we can let the collar slide forward.

Lastly, we'll go over one measurement and that's the overall length of the coupler. It measures about 16-1/2 inches. That's it for a quick look at the Bulldog collar lock coupler with low-profile latch, part number BD028499. .

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.

Ordering the coupler was extremely easy and etrailer com responded acknowledging my order and shipped it asap. I think the organization and professionalism exhibited by etrailer.com is outstanding!

Exactly what I needed to fix my horse trailer. Arrive on time. Awesome.

Best coupler ever - well worth the slightly higher cost. Very easy to operate and slightly more tolerant of misalignment with the ball when hitching up. I keep a plastic deadblow hammer handy to operate it. Way more secure attachment then the cheap Mau coupler that came with trailer which came uncoupled by itself.

This is exactly what I was looking for. This is a very good heavy coupler. It is replacing a 5K surge brake toledo bulldog coupler on a trailer I have beefed up with 600# of steel to the 10K level. To save $$$ and maintenance issues I am going to electric brakes after I decide on current axles or not. Very speedy shipping: I did not expect to see it untill 16 July 12. I have ordered from you several times and you have always exceeded my service expectations and your prices are very competitive.

I'm a fan of Bulldog hitches. This product needs a little fine tuning on arrival. Very difficult to get the retaining pin in or out, I'll need to polish up the holes a bit. Once broken in I'm sure it will be just as functional and dependable as all the other Bulldog hitches on the road.

I purchased a Bulldog coupler to replace a damaged one. Recieved product with rust plumes under paint. Had to bend sliding handle on lock to make it work. Not enough hassle to return- its just a hitch.

I love the bulldog-collar-lok coupler. I used it to replace a broken coupler that never quite worked right. The collar lock coupler is much easier to take on and off the ball. Locking is simple, effective and easily verified for safety. Installation was easy. Pull off the old coupler assembley (torch or plasma cutter works great). clean up the work surface removing old welds. Weld it onto the frame, ensuring the frame is evenly touching on all sides and bottom. touching. Final step...go back to hunting !!

Appears to be a refurbished unit, has several rust spots. Collar does not align very well with the shank of the coupler clam. Retaining pin holes a tad small. Needs some lubricant for the collar, retaining pin holes reamed out a little, and a hammer to help open the collar. All that said, I did get it delivered to my door at a price that was agreeable and better than everyone else. It also arrived about 4 days earlier than expected. Hope my welder does not have plans Saturday. I have bought from etrailer before and will continue to do so. They have a good selection of products and good prices. Service is always fast and courtesy and they followup with you unlike most suppliers.

I needed a new coupler for a custom trailer I built. I love this style of coupler on my bumper pulls. Etrailer was great, product was easy to find and great price. Product shipped fast and easier than running to local store to pay more and not find what you need.

Best trailer tongue made! Great price and fast shipping..Very satified with etrailer!

This product was purchased to replace an existing hitch that could only use a cheap hitch cover lock. After already having one trailer stolen this year security has become a priority. With this coupler we can use a heavy duty lock that covers the entire coupler and making it much more difficult to steal. Bulldog products always work for us.

What's not to like? Bulldog builds stout products, and etrailer got it here quickly.

The hitch is the exact same hitch as my local farm store but it was nearly $40 (30% discount ) cheaper. It took 3 business days to get here, but I was in no hurry. It was worth the wait.

  • What is Difference Between High and Low Profile Bulldog Couplers
    The difference between the low profile latch Bulldog coupler part # BD028499 and the high profile coupler part # BD028463 is the height of the latch and it's design that pulls the collar back. It's really personal preference between the two. Whichever you would want to use would be the way to go. Only real thing to consider would be clearance. If for some reason you didn't have the clearance for the high profile you would need to go with the low profile. I attached review videos for...

    I looked up pictures of the 2001 Thuro Bilt trailer you said you have and they have an a-frame with an interesting angle, but the part # BD028499 does seem to be mounted on top of it so this would work. Then for a jack a top wind jack like the Pro Series part # PS1400600303 would work well as that's also what's used in all of the pictures I saw. If you wanted a wheel caster you'd also want the part # PS1400750340.

For a bolt on option, you may be interested in the Bulldog Heavy-Duty Cast Head Coupler w/ Wedge Latch - 2-5/16" Ball - A-Frame - 15,000 lbs, # BD44150WH301, that has the wedge latch.

  • Recommended Coupler Style for 1956 Spartan Royal Mansion Trailer
    A collar lock coupler like the Bulldog # BD028499 is going to be generally easier to operate and less likely to have latching difficulties because of the larger moving parts. With a collar style coupler, it is easier to visually confirm when the coupler is properly secured around the hitch ball. Because of this, I do recommend a collar lock style, but it is really mostly a matter of personal preference. Either style will be reliable for long trips and will work great on your 1956 Spartan...

  • Does the 12.5K Bulldog Collar-Lok Coupler have a Tongue Weight Rating
    Believe it or not but you almost never see tongue weight ratings on trailer couplers. But the best thing to do is stay at 10 to 15 percent of the gross weight capacity. Bulldog coupler # BD028499 is rated for 12,500 pounds gross trailer weight but doesn't have a listed tongue weight capacity. So at 10 to 15 percent that would be 1,250 pounds to 1,875 pounds. But you would still be limited to the tongue weight rating specified by the trailer manufacturer (if applicable). I have linked a...

  • Could Bulldog Collar Lok Coupler be Used on a Travel Trailer
    The Bulldog Collar Lok part # BD028499 that you referenced would be a great option for your travel trailer. Typically this style is used on construction trailers but it's an excellent design that is very reliable so it would be a great option for you as well. There's nothing about it that prevents it from being used on a travel trailer.

  • Replacement 12,500 lb Rated Bulldog Collar Lok Coupler Recommendation
    You are going to need to replace the entire Bulldog coupler that you have on your trailer. We do not sell replacement parts for the Collar Lok couplers. Besides most likely you damaged enough of the coupler that replacing the entire thing would be the smartest route. Since I can't tell which style coupler you have I attached a link that has all of the 12.5k rated Bulldog couplers we offer that have various attachment styles.

  • Recommended Lock for Bulldog BD028499 Collar-Lok Trailer Coupler
    The Bulldog # BD028499 Collar-Lok coupler is about 2-3/4 inches wide at the point of the coupler where the locking pin is located, so the # e98887 lock you'd looked at wouldn't have a long enough span to work for you. I'd recommend the same lock with a longer span, part # e98888 which would fit just fine. For a more secure lock that's specifically designed to work with a coupler like this, I'd go with the Blalock # BLTL-20-40D which would be harder to defeat and would provide a higher...

  • Recommended Lock for Demco DM14040-81 Coupler
    The # BLTL-23 Blaylock coupler lock is compatible with a very specific type of coupler, the CollarLok like our part # BD028499, so it wouldn't be a good fit for a coupler like the Demco # DM14040-81. A lock like the # DT25013KA or a latch type lock such as # 2847DAT would be your best fits.

As long as your pin diameter on the Bulldog coupler is larger than a 1/4 inch and the span is no bigger than 3-3/8 inches, then this coupler lock will work for you. I pulled the Bulldog coupler # BD028287 you had looked at from our warehouse and a similar style 2-5/16 inch # BD028499 and measured the size of the lock pin that goes in the coupler.

    The distance between the center of the ball hole to the center of the circle used for A-frame jacks on the part # BD44125W0317 that you referenced is 12-1/2 inches. I confirmed this with my contact at Bulldog. The advantages between the latching styles of the wedge latch in the # BD44125W0317 and the collar lock like in part # BD028499 is largely personal preference. But the wedge is easier to lock with an anti-theft device. The collar lock style is more rugged and crude design with...
