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.

Thankfully etrailer shipped one by ups that got here in 2 days thanks etrailer for taking care of their customers

They are absolutely the best for a bumper pull trailer no worries about popping off the ball

Haven’t installed it yet but looks like it will work just fine.

Product was as promised, they had to backorder 1 of the hitches and I still received it faster than I was able to get the other 2 installed. Great service and really fast shipping....I will order from them again.

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.


Comments
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


Don’t buy this!!! It literally does not work. You can’t open the coupling because it was built incorrectly. There isn’t enough room to slide the coupling back. Of course I didn’t realize this until I had mounted it on my trailer. etrailer customer service is about to get an earful!

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


Extremely happy with my purchase. It took awhile to receive but not do to e trailer but to a manufacturer back order. I was kept up to date on the status of my order and even offered a similar substitute that was available to ship immediately but I choose to wait for what I had ordered. Nothing but great things to say about the product and the staff at E trailer

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


Used it on a gravity wagon we haul cow feed from the feed mill. Welded right up to the trailer tongue and makes the trailer pull better than the old pin hitch.

  • How Does the Bulldog Collar-Lok Coupler w/ Pin, part # BD028444, Mount to the Trailer Frame
    Yes, this Bulldog Collar-Lok Coupler w/ Pin - 2-5/16 inch Ball - 3 inch Channel Tongue - 12,500 lbs, part # BD028444, is designed to fit onto a 3 inch rectangular trailer frame. The slight indentations you see on either side of the coupler most likely are the result of the stamping process to create the curve in the coupler that begins right after the indentations. You will want to mount this coupler in as far onto the frame as you can without causing damage to the coupler. If the indentations...

  • Coupler Lock Recommendations for a RAM Brand Trailer
    If your RAM brand trailer has a collar-lock style coupler like the Bulldog Coupler # BD028444 yes the EZ Lock Trailer Coupler Lock # BLTL-20-40D would be an excellent choice as a trailer lock. A more universal coupler lock that we offer is the Fastway Coupler Lock part # DT25013KA. I attached review videos for both coupler locks for you to check out.

  • Recommended Trailer Coupler and Locks for Rollback Car Trailer with 3 Inch Tongue

This will secure your 3 inch x 3 inch receiver tube and accessory.
