Video Transcript for Bulldog Straight Tongue Trailer Coupler - Standard Coupler - BD028444 Review

Today were going to take a quick look at the Bulldog Collar Lock Coupler with pin part number bd028444. Now Bulldog covers this coupler with a limited five year warranty. It has a gross trailer weight capacity of 12,500 pounds. Well go over a quick measurement with you. The overall length of the coupler is about 16 and half inches. This is a weld on coupler and while you weld it to the tongue of the trailer along the edges of the coupler.

Its built to be used with three inch wide tongue trailers. Well take an inside width measurement here and we get our three inches. The bulldog latch system is a little bit different. Theres a hinge jaw here that needs to open in order to release the ball or fit a ball in when coupling up. To do this youll slide the collar back and the spring loaded jaw will open up.

To slide our collar back far enough we need to remove this pin. Once we remove the pin we can take our collar and slide it back and the jaw will open. The jaw has a stop here that will hold the collar back into place while you hookup or unhook your trailer. Once you get the coupler fitted over the ball take some tension off the collar, push in the hinge jaw and let the collar slide forward. At this point the ball would be locked into place.

Now well show you how it works with an actual two and five sixteenth trailer ball. Slide our collar back and the jaw pops open. Well fit our ball into place, close the jaw and let the collar slide forward over it. Now our ball is completely captive and itll allow smooth rotation to keep the trailer tracking nicely behind the vehicle. Again to remove it slide the collar back, the jaw pops open and the ball is free.

Once you have everything connected to your trailer ball slide the pin back into place and fit the clip over it. Now the pin is also attached to the coupler via chain so that you dont lose it. Thats it for a quick look at the Bulldog Collar Lock Coupler with pin part number bd028444.

Review from a similar Collar-Lok in Straight Tongue 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 Straight Tongue 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 Straight Tongue 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 Straight Tongue 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

Review from a similar Collar-Lok in Straight Tongue 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.
