Video Transcript for Bulldog Straight Tongue Trailer Coupler - Standard Coupler - BD028244 Review

Today were going to take a quick look at the Bulldog Collar Lock Coupler with pin part number bd028244. Now this is a weld on design so youre going to weld it directly to the tongue of your trailer coupler along the edge here and on the back. Its designed to be used with three inch trailer tongues. Well measure the inside width and again we get our three inches. Well also quickly measure our overall length and we get about 16 and a quarter inches. Now the coupler itself is made out of high strength steel so its very durable.

The collar lock system is a little bit different than typical trailer systems. The collar will slide back releasing this hinge and the socket opens up so you can get the ball in or out. To be able to release it the collar needs to slide back far enough so we need to remove our pin first. Theyve secured the pin to the coupler with a chain lanyard to make sure you dont lose it. With the pin out of the way we can slide our coupler down and this wedge here will release and swing open.

Theres the little hook here that will hold it open while you get the ball fitted into your coupler. Weve got a two inch trailer ball. Well fit it into place and then as we close the wedge the spring loaded collar will slide forward securing the wedge side around the ball. This provides a nice captive snug fit around the ball to insure that the trailer doesnt come undone. Once the balls engaged in place you can then re-insert your pin and secure it.

Thisll prevent the collar from coming back and releasing while youre trailering down the road. To release the ball well just reverse the process. Again the pins removed so we can slide our collar back. The wedge opens up and the ball is free. Thats it for a quick look at the Bulldog Collar Lock Coupler with pin part number bd028244..

Heavy-duty coupler has a pin-style securing mechanism and hinged ball socket with visual indication of proper closure around the ball - all to ensure quick, easy and secure hookup. Designed for use with square or rectangular tongues.


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.


I was having trouble finding a longer coupler to extend the tongue on my boat trailer and went online to locate what exactly I needed. After some frustration searching different sites, I found the perfect coupler on! It's been a year since I installed it and I'm happy to say it's still working perfectly! Highly recommend for difficult to find items for your trailer needs!


It should be a law that all trailers have bulldog type hitches. Over the years I have had two trailers come unhooked when I thought they were correctly hooked but instead were closed above the ball and not securely on the ball. More expensive but worth it!


Don't waste your time with any other style coupler! Weld it on and never have to think twice about the security of the trailer connection. The only drawback that I can think of is that I had my trailer hot-dip galvanized after fabrication, and the design of the coupler is not conducive to that process (cannot be disassembled), so I had to paint it instead, but it is a small price to pay for having the extra piece of mind with a welded setup.


Exactly what I ordered and came very quick will order from them again!


Works like a charm, I couldn't be any h appier

It is an honest up to date upgrade. I HIGHLY recommend it
Eric B - 10/19/2021


Installed new coupler on wheeled fish. I unhook and hook up a lot. Old style ball hitch was difficult to unhook, new style will just slip on and off without issue of getting caught. New ball hitch is also suppose to be the safest on the market. So far working perfect.


The Bulldog coupler was as promised and advertised. I will use these couplers in an industrial setting, so high quality and timely delivery are very important to me. I found, however, that delivery was greatly improved by calling and talking to a person (thanks Rose) rather than depending on the online anonymity and predefined processes. Perhaps adding an optional field that defines "when a product is needed" can help. I will do business with "etrailer" in the future.


Found exactly what I was looking for on, received the hitch within 5 days of placeing the order. The Bulldog Collar will be a great replacement and improvement for the old coupler on the boat trailer.


Have always used Bulldog hitches - over 30 years. Excellent product.

Been using Bulldog products for years. Always performed as advertised.

All the parts came on time and they were the right ones. Can't ask for more!


Great Product. Much better than the cheap couplers that come on the trailers offered on the market.

Thanks Jeff

  • Can Trailer Coupler for 3 Inch Wide Tongue Fit 2 Inch Wide Trailer Tongue
    Usually you want to have a coupler that fits the exact channel size on your trailer tongue but you should still be able to get a coupler designed for a 3" channel, like the Bulldog Collar-Lok Coupler w/ Pin # BD028244, to fit your 2" trailer tongue by welding on some shims to take up the extra 1/2" on either side of your tongue. I recommend having a professional welder do this for you so they will know how to get the welds exactly right for this type of application.

  • Will the Bulldog High-Profile Coupler Latch Repair Kit Work on a Bulldog 2B Hammerblow Coupler
    There are several different styles of Bulldog 2B coupler latches. If your coupler has the high profile latch like the one on our Bulldog Collar-Lok Coupler w/ High-Profile Latch, item # BD028462, the Bulldog High-Profile Latch Repair Kit, item # BD024200, will be the correct replacement.

    I recommend going with a Demco Channel Tongue Trailer Coupler # DM13689-95 on your Tracker Trailstar boat trailer as the Bulldog Collar-Lok Coupler w/ Pin # BD028244 is designed to be welded on. If it is not welded on as per the manufacturers intended usage you could develop issues with the coupler.

  • Lock Recommendation for Bulldog Collar-Lok Trailer Coupler
    I'm assuming you have a Bulldog Collar-Lok trailer coupler like the # BD028244 you'd looked at. Blaylock makes a lock specifically designed for a Bulldog Collar-Lok trailer coupler, part # BLTL-20-40D. The lock includes the lock assembly itself as well as the locking pin and disc padlock. I'll link you to a demonstration video featuring the # BLTL-20-40D coupler lock.

  • Lock Recommendations for a Collar-Lok Style Trailer Coupler
    It sounds like you have a Collar-Lok coupler such as # BD028244. For that type of coupler you could use lock # BLTL-23. The body is aluminum but the pin inside that goes way up into the coupler is steel. It fits 2-5/16 inch Collar-Lok couplers. For 2 inch models use # BLTL-22. Another option, if your coupler has the pin behind the collar to keep the collar from sliding back, is to use a lock such as # e98888 in place of the pin. This would prevent the collar from opening all the way. Or,...
