Video Transcript for Bulldog Adjustable Trailer Coupler - Coupler Only - BD028390 Review

Today were going to take a quick look at the Bulldog collar lock coupler with pin part #: BD028390. Now Bulldog covers this coupler with a limited five year warranty. It has gross trailer weight capacity of 7,000lbs and its designed to work with 2 inch trailer balls. This style of coupler comes with a pair of bolts that youll use to mount this coupler to a channel bracket. A channel bracket will look something similar to this. Were going to go ahead and measure the outside width here and we get 2 7/8 inches.

So you want to make sure that it will fit the bracket that you already have on your trailer. The overall length of coupler measures about 9 inches. Now I want to show you how this coupler system works. Theres a collar here that needs to slide back in order to release this hinge jaw on the couplers head. In order to do that well need to remove this pin so the collar could move back far enough.

Now the pin is secured to our coupler with a chain lanyard. That way you dont lose the pin. To open our coupler well just slide the collar back. The hinged jaw will pop open as its spring loaded. This will create a large enough opening to get your trailer ball in and out.

To close it pull the collar back, hold the jaw closed and let the collar slide back into position over the jaw. Now weve got a 2 inch trailer ball with us so well show you how it works in conjunction with the ball. Again, well slide the collar back, the jaw pops open and provides a shoulder for the collar to rest on while youre hooking or unhooking your trailer. Well fit the ball into place, hold the jaw closed and again let the collar slide forward. Now our ball is completely captive, but it has enough movement that the trailer should track nicely behind our vehicle.

Again, to remove the ball slide the collar back and the ball pops free. Well reinstall our pin and secure it with the clip. And thats it for our quick look at the Bulldog collar lock coupler with pin part #: BD028390.

We ordered this on 5/27 and installed it on a burial vault trailer. Two weeks later, the pin holding the collar together fell out while in transit. 659505

Was the snapper pin secured correctly? The only way I could see this happening is if the bail wasnt secured over the snapper pin and it wasnt closed.

Hitch clamp is great quality material but sometimes hard to open. This is because the sleeve does not have support lever to pull back. I have a similar hitch that has a lever which pulls the sleeve when it needs to be opened. That makes it much easier. 617422

It was just as stated on the web site. I bought it to replace the one that was already on our concession trailer since we bought a different vehicle to pull it with. 182563

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. 149482

Review from a similar Collar-Lok in Adjustable 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

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 Adjustable 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

Review from a similar Collar-Lok in Adjustable Trailer Coupler


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

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

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

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

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.

Review from a similar Collar-Lok in Adjustable Trailer Coupler


Could not be more happy with this trailer hitch. Just two days after I got the hitch welded to my trailer I had to make an emergency run to Louisiana from north Mississippi to help my Step-father get back home. Drove all the way there and had to load the GMC Yukon. I was a little scared of the untested trailer, but we made the hole trip over some very rough roads without issue. I would recommend this hitch for any trailer. 816335
