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 Coupler in Straight Tongue 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 Straight Tongue 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.

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


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.

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

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


The couplers (3) are of excellent quality. Ordering was very simple by telephone. All questions were answered. Shipping was immediate and the product arrived in an unmolested box which surprised me due to the weight. I expected the box to be dented and the corners smashed. Tracking of shipments was important to me. Couplers will be installed on a rather unique vehicle. Each of the three cars of this miniture train will receive the new couplers.

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


I recently sold a dump trailer that had a Bulldog 2 inch hitch on it. The new dump trailer I purchased is smaller but has a Chinese 2 5/16" hitch for some reason. I really like the Bulldog style and since everything else I have is 2", I purchased this to replace the one that came on it. As a self employed mechanic I have recommended my customer's use etrailer for supplies I use for them. They and I have always had a pleasant experience. Thank you!


Comments
Sometimes, those shiny metal formed hitches can be difficult to on the ball without the latch getting in the way. And, maybe you think its locked down when it isnt. Thats why I cut those types off and install a cast iron Bull Dog. Simple to on and simple to secure. No guesswork.
