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.

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. 337

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. 203248


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.

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


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. 47860

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


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. 310645

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


Excellent Coupler with low price. I replaced the older Bulldog hitch with this one. The channels made it easy to weld it onto 3" channel iron. I prefer the low profile style, instead of the high profile model. I also purchased a lock from etrailer.com that goes through the hitch, replacing the normal clip that it comes with ( pn 28012). They also shipped me a 2" receiver hitch lock ( pn 7683) for my truck, and they keyed the two locks to the same key. 191173

Replacement for worn out receiver on old trailer. Wish Bulldog were made in the USA, not Mexico. But, the others are made in China, which is even worse. 92372


Comments
No problems. Remember to keep a hand on the lever when squeezing shut and let the slide close gradually so you dont pinch your other hand. I keep mine lubed with bicycle chain lube with Teflon. Also, i always grease the ball. Yes, that is messy but the metal-to-metal squealing is prevented and your coupler will last forever.

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. 265563

Review from a similar Collar-Lok 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. 469915

  • 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.

  • 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...

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Alternative to Blaylock Total-Encasement Coupler Lock that Fits Standard Lipped Couplers
    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,...

  • 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.

  • 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...

  • 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...

  • 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.
