Video Transcript for Bulldog A-Frame Trailer Coupler - Standard Coupler - BD028463 Review

Today were going to take a quick look at the Bulldog collar lock Coupler with high profile latch part number bd028463. Bulldog covers this coupler with limited five year warranty. It has a 12,500 pound gross trailer weight capacity. Its designed to work with 50 degree A-frame trailers. It has the standard cut and bolt pattern cut to mount a trailer jack. Now well show you how this jack operates.

It comes included with a pin that fits through the latch mechanism to prevent it from being opened. You can replace this pin with a coupler lock, sold separately, that will also secure the latch and prevent it from coming open while trailering down the road but itll also help protect against theft when you have your trailer stored. As for the mechanism well lift the handle, this collar slides back so that the spring loaded hinge jaw can open up and release the ball. Well lift our latch, the collar moves back and the jaw pops out. Well hold the jaw in and close the collar over it.

Now weve got with us a two and five sixteenth ball so well show you how it works with an actual ball. Pull our latch open. The hinge jaw pops open and it provides a little stop here for the collar to rest so you dont have to worry about it closing when youre hooking or unhooking your trailer. Weve got a two and five sixteenth ball that well fit into the socket. We can then close our jaw and let the collar close over it.

Now our ball is completely captive but it allows enough movement for it to track nicely behind eh vehicle. Well pull open our jaw and our balls free. Thats it for a quick look at the Bulldog collar lock Coupler with high profile latch for two and five sixteenth balls part number bd028463.

I've used these types of couplers before on my other trailers and love them! Simple operation and gives me a very secure feeling this will never come off my ball hitch. This coupler is to replace my old hard-to-operate other style coupler on my flat bed car hauler. Would've given 5 stars if it weren't that I had to work the spring loaded latch back and forth many many times and with lubrication to finally become semi-free in operation.


Comments
Spring loaded clam shell still stiff in opening completely. Other than that, factory welds are showing no signs of stress or cracks. Original star rating remains the same.

Easiest hook up there is. The first time I bought one of these connectors I was in Texas. They are easy to find out there. Well I have a problem with my tow vehicle. It has a spare tire hanging right on top of my receiver ball. The connector that came with the trailer required about 6+" of space between the ball and the tire, which I did not have, I could lengthen the ball out which I definately wanted to avoid. This connector was the answer to my situation. I went up north last weekend to visit my son and when I got back this connector was setting on my front porch, this was about 4:30 PM. Before I went to bed it was installed on my trailer, after I cut the existing one off ofcourse. This connector connects up like a dream, it's self centering, has no adjustments, so you do not have to worry if it is too tight or too loose and may come apart. I modified the toung on my last trailer also and used this same connector, it's neat, sweet and compleat. I may be in the market for a load leveler kit.

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


This is the second bulldog I have purchased from Etrailer. I just sold my trailer the second one is for my new trailer. I got the high profile one this time, I have arthritis in my hands. The lever gives me a better grip and it’s a lot easier on my hands. The bulldog is so easy to hitch and unhitch!

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


Somehow my old hitch was damaged and a new hitch was required since the moving parts are not replaceable. The old hitch was a pain to use - it required an extra drop to get the ball into proper position, and it required my jumping on the bumper for extra lift to get the ball to release. This hitch will solve the hard-to-attach, hard-to-release issues thanks to the side opening design. It is also nice to have that positive visual feedback that everything is in the proper position prior to drive-away. The one disappointment is that the latch requires a lot of hand strength to operate. I am hoping that once installed that an application of WD-40 will overcome some of the friction in the mechanism. Time will tell. It is possible that I may have been happier with the high profile design for more leverage. Hard to know.

This is a perfect replacement for the one that broke, first of all my trailer was stolen, thanks to Las Vegas Metro police department they recovered it. The genius's that stole the trailer didn't understand how this coupler worked and it must have come loose. This was a perfect replacement, I cut the old one off, installed the new coupler, and my trailer is back to normal, in fact it's loaded up for a very large job tonight.

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

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.

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


Arrived promptly. Well packaged and went on without a hitch. Mounted it on with grade 5 bolts instead of welding it on in case I ever need to replace it or want to put it on a different trailer. Just a tip use 4 in x1/2 bolts with a lock nut and it’s a perfect fit.

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.

WOW. A company that apparently really cares. "Just what I wanted" was my husbands remark about the hitch receiver. He could not been happier with the purchase as well as the attention shown him through emails. The shipping time was super, especially as we ordered it during Christmas rush. Thank you. I know you will be his "go to place" and has already told several people about you.

been a year and husband still tells people what a great place to shop. Clearly living up to his expectations and that says A LOT!

  • Bolt-on Trailer Coupler to Replace Bulldog # BD028463
    You could drill into the Bulldog # BD028463 and make it a bolt-on but that's not really ideal. We don't have the exact match in a bolt-on model. We do have part # BD44150WH301 for a bolt-on Bulldog coupler. It has a higher rating but the price tag is quite a bit more. Another option is a Demco coupler. Part # DM16680-52 has even more weight capacity and a nice latch. It fits the same ball size and bolt pattern as well.

  • Will Bulldog A-Frame Jack Fit Bulldog Collar-Lok A-Frame Coupler
    Yes, the Bulldog jack # BD155033 is an exact fit for the # BD028463 Bulldog coupler. Both the jack and the coupler's hole are 2-1/4 inches. Most A-frame jacks are a universal fit.

  • What are the Dimensions of the Bulldog Collar-Lok Coupler, # BD028463
    I went out to the warehouse to measure a Bulldog Collar-Lok Coupler, # BD028463. It is 17-5/8 inches long (overall). The rear portion is 2-7/8 inches tall and 11-1/2 inches wide at the widest point. The holes for mounting a jack are 3 inches apart on center. The diameter of the jack hole is 2-1/4 inches long. From the bottom of the coupler to the top of the latch when in the closed position is 5-1/2 inches. When open it is 7-3/4 inches. The collar has a 2-5/8 inch diameter. The coupler...

  • Collar Lok/ Hammer Blow Repair Kit Recommendation
    The Bulldog Collar-Lok Coupler w/ High-Profile Latch # BD028463 that you referenced used be called a hammerblow style coupler. The rebuild kit you would need that comes with the spring and pin is the part # BD024200.

  • Wide A-Frame Coupler Recommendation for a Trailer
    I did some checking and the a-frame coupler with the most distance at the widest point is the Bulldog Collar-Lok coupler part # BD028384. This coupler has a 11 inches at the widest point. Is there a reason you need one that wide? All that really matters is the angle of the coupler as it matches your frame. Nearly all A-frame trailer have a 50 degree angle where the coupler installs. The # BD028463 would install on a 50 degree angled A-frame trailer.

  • How Does a Hammer Blow Trailer Coupler Work and Function
    The HammerBlow Trailer Coupler, like the # BD028463 is a coupler that will mount to the from frame of a trailer and be used to attach to a hitch ball on the back of a vehicle. It mounts to 50 degree A-Frame Tongue and will couple to a 2-5/16 in hitch ball. It has a 12,500 lb weight capacity. I have included a product demonstration video for your reference, and a helpful article about trailer couplers.

  • Location of VIN on Hammerblow Car Hauler Trailer
    A trailer's 17-digit VIN will usually be located near the tongue area on an inside-facing surface where the information will be protected from impacts from road debris. Although this placement is common there is no absolute rule about where a trailer manufacturer has to place the VIN. The linked photo shows an example of a 17-digit VIN. The Hammerblow trailer company from Wausau, Wisconsin was bought out by Cequent Performance Products, which is now known as Horizon Global. I checked...

  • Solution for Collar Lok Style Coupler with Broken Latch Mechanism
    Just the piece you broke on your Hammblow coupler is not replaceable. Only solution would be a new coupler like the Bulldog Collar Lok part # BD028463 that you referenced. Most likely your coupler is fatigued elsewhere too based on it breaking like yours did.

  • Coupler Lock for Bulldog Collar-Lok Coupler
    Hi. You would not have needed to make a hole in the Bulldog Collar-Lok Coupler # BD028463 to lock it, you would only need to use Trailer Coupler Lock # e98888. This lock would go through the latch where the pin is to secure your coupler.

    Thank you for sending the photo! While I have a solution for you, the Blaylock Total-Encasement Coupler Lock, part # BLTL-23 will not work. I is designed to fit Bulldog Collar-Lok style couplers that use a 2-5/16" ball, like # BD028463 for example. For a lipped coupler, like yours, Blaylock does offer the EZ Lock Trailer Coupler Lock for 2-5/16" Lipped Couplers - Aluminum - Push Button # BLTL-34. Or, if you prefer something that provides a more complete enclosure for your coupler,...

  • Is a Bulldog Collar Harder to Latch Than a Wedge A-Frame Trailer Coupler
    In regards to the Bulldog Collar-Lok Coupler w/ High-Profile Latch part # BD028463, you will indeed need to be more centered over the hitch ball in order to couple in comparison to the Bulldog Heavy-Duty Cast Head Coupler w/ Wedge Latch part # BD44125W0317 which will more or less center itself with enough pressure. For that reason, I do prefer the trigger/wedge style.

  • Will Replacement Coupler Cap Spring # BD500354 Work on 2-5/16" Ball Coupler
    The Replacement Coupler Cap Spring # BD500354 is specific to certain model Bulldog Collar-Lok Couplers, however it can indeed be used on a 2-5/16" ball coupler as it's a confirmed fit for the Bulldog Collar-Lok # BD028463. If this is what you have the spring will work perfectly as a replacement. If you have a different model coupler just let me know and I will be happy to see if we have a better solution available.

  • 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...

  • Recommended A-Frame Coupler for Flatbed/Car Hauler Trailer
    The Yoke style or Collar-Lok style couples are definitely the best to use when it comes to loading heavy weight in a trailer, like a car. I recommend looking into the weight of your trailer and the vehicle you plan on hauling before deciding on a coupler. The A-Frame Trailer Coupler # CA-5210-B is a great option that is rated for up to 8,000 lbs but if you are needing something rated even higher than that the Bulldog Collar-Lok # BD028463 or # BD028499 is the better route to go as they...
