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


Five star service from etrailer, and maybe a two or three-star product from Bulldog. Aside from the rust and the fact that the collar is so stiff that it can't be operated by hand, the fabrication on the steel attachment plate is poor. The holes for the tongue jack are punched out, twice in some cases, resulting in an enlarged hole, but there are no threads for the tongue jack so you'll have to fumble around and use nuts underneath. The vertical angles on the steel are wrong, so it will splay out at the bottom and won't fit tightly to the A-frame and you will need to shim it out. The interior of the casting is full of weld spatter that will chafe the tow ball. I bought the less-expensive Ram sleeve-lock coupler under a Curt label and the fabrication is much better, having none of the problems the BullDog did. etrailer kindly sent me an RMA to return the BullDog.

We hate to see rust and other complications when it comes to the products that we sell. I have sent this information over to our customer service team for them to contact you.

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


The Bulldog coupler is SO MUCH easier to hitch up and disengage than my previous coupler which required several back and forth movements of my tow vehicle to engage/disengage the hitch ball.

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


A great product. The original crappy hitch on our new trailer was always a real pain to unhitch. Typically would have to keep the trailer wheels chocked and let the tow vehicle (no brakes and in neutral) roll forward or back freely while raising the tongue - only then would the ball be released from the ball socket. Not good when on a slope. A few times we actually had to pull out the 5/8" ball mount pin and drive forward and let the ball mount slide out of the receiver. No issues at all with the Bulldog hitch. And it's nice to have the positive and easy-to-verify clam-shell hitch mechanism instead of the sliding yoke lock of the original hitch. $200 bucks to have the old hitch torched and ground off and the Bulldog welded on. Money and time well spent.

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


Solid coupler a good company. The coupler doesn’t have any mechanism to assist in sliding the collar back but I welded on to nubs to pull it back with. I wanted several Master disk padlocks keyed alike but Etrailer could not get those for me so I went with a different online trailer co. that offered a six pack of them at a good price.

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


After purchasing a trailer that came with a Collar-Lok coupler standard, we decided to swap out more of our standard couplers over to the this style. So far this product has held up very well. The only downside is the finish/coating is a bit cheap and it started showing corrosion within a few weeks.


Comments
What I recommend is touching up the coupler with a rust resistant spray to help prevent rust.

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


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.

Product was exactly as advertised, and got here earlier than expected. I plan to use it on an old pickup truck frame which I am converting into a pull behind trailer. Staff very helpful and efficient.
