Video Transcript for Bulldog A-Frame Trailer Coupler - Standard Coupler - BD44150WH301 Review

Today, we're going to review part number BD44150WH301. This is the Bulldog Heavy-Duty A-Frame Coupler with the Cast Head and a Wedge Latch. This Bulldog durable cast coupler features the easy-to-use wedge latch that's right here for quick coup up. It has a built in attachment point for round A-frame utility jacks. This heavy-duty bolt on coupler is ideal for use with a utility livestock, cargo or construction trailer. It has a wedge style latch that you can see underneath, which is secure and easy to use.

It has the built-in attachment point for the jack and this is an A-frame design coupler which means it will mount to a 50-degree trailer tongue. This does fit on a ball size of 2-5/16 and, basically, what you would do is there's a pin here that locks the latch in place. Just pull that pin out. Actually, there's a release right here underneath that if you pull up on that release it will allow you to pull up on the lever, and you can slide your pin back and it will keep it in the open position. And what that basically does is move the wedge latch which is right in here off of the ball so you can release the coupler from the ball.

And then if you go to lock it over the ball if you watch that wedge latch, pull the pin out and if you release the latch it will slide up on top of the ball. And once you know it's in position, the latch will fall down in place and then just put the pin in to lock into place over the ball. The overall length on this coupler is 18 inches. It does have a weight capacity of 15,000 pounds. It does come with a five-year limited warranty.

And again, here's the location for the three-hole A-frame utility jack to bolt on to. And that should do it for our review of part number BD44150WH301.

Item ok. Buyers need to determine where they plan to attach there safety chains. The Fulton Unit I was replacing had a better location for safety chain connection. The two 1/2 holes dont allow for easy chain connection die to very limited space. 183351

Comments

Not a problem on the review. Im glad to help. I recall I was mainly writing the review because of e-trailers service, which is outstanding. The coupler, on the other hand, I dont really like. We have purchased about two dozen of these couplers from our main vendor over the past year and a half for a special line of trailers we are doing. *I purchased that one from e-trailer since we were in a pinch with our main vendor. These couplers, while appearing to be very heavy duty, they have a flaw that is pretty frustrating. If the customer happens to forget to unlock the coupler before letting their jack down, or vice-versa when hooking up, this puts a bit of stress on the bolt inside the locking mechanism. This bolt comes pre-bent from the factory and the design, in my opinion, is not good. The bolt is bent on the threads of the bolt and this weakens the bolt. The bolt needs a very tight tolerance angle in order for the locking mechanism to function properly. Ifwhen the customers hitch ball jams up in there in any way, after repeated times, the bolts bent angle changes which greatly affects the travel of the locking mechanism. Often it results in a complete failure of the coupler itself since the locking mechanism is now junk. All that said...I would not recommend this coupler. We are only continuing to use them since it is what our marketing folks specd and we have a signed contract and were only building a few more and then were completely done with that. Sorry for the long story. I hope its helpful info for you.

I am now in the process of removing the old (El Cheapo) coupler that came with my (El Cheapo) tow-behind travel trailer and installing this serious-serious "Bulldog" coupler because I never again hope to be out with a crowbar trying to disconnect my tow vehicle from my trailer! A bit of dignity afforded by replacing a $33 item with a $142 item is, as is said, priceless. I read the earlier reviews and, as an engineer, will be surprised if I ever again need that crowbar with this fine piece of machinery!!! 249752

The original one I had on my Featherlite enclosed car trailer cracked and I wanted one that had the holes predrilled to align with the existing holes in the A frame.

Real nice piece and great customer support...Thank You!!! 206966

This a heavy-duty connector that I am using to replace a broken one on my flatbed trailer. This unit is designed well and fit as it should onto the A-frame of the trailer.( Once I got the old hitch cut off with a grinder!) The ball receiver is very solid and the latch hitch, I think, will be better than what I had, which was a wrap-around type that broke. I plan on adding a couple of spot welds just as insurance, although using 12 Grade 8 bolts will certainly hold the thing just fine. 151977

Ask the Experts about this Bulldog A-Frame Trailer Coupler
Do you have a question about this A-Frame Trailer Coupler?


  • Yoke Style Coupler Replacement for 2-5/16 Inch Hitch Ball Compatibilty
  • Unfortunately we don't have a repair kit at this time. If you choose to replace the entire coupler, I recommend the Bulldog Collar-Lok Coupler w/ Low-Profile Latch - 2-5/16" Ball - A-Frame - 12,500 lbs # BD028499. For a bolt on option, you may be interested in the Bulldog Heavy-Duty Cast Head Coupler w/ Wedge Latch - 2-5/16" Ball - A-Frame - 15,000 lbs, # BD44150WH301, that has the wedge latch.

  • Is There A Bolt-On Collar Lock Style Coupler For 5,000-7,000 lb Application?

We also have the Bulldog Heavy-Duty Cast Head Coupler w/ Wedge Latch - 2-5/16" Ball - A-Frame - 15,000 lbs # BD44150WH301.

  • What Hardware is Needed for the Bulldog Heavy-Duty Cast Head Coupler With Wedge Latch
  • The Bulldog Heavy-Duty A-Frame Coupler, # BD44150WH301, does not come with the attachment bolts. I have attached two images showing the bolt pattern measurements and the bolt hole sizes. I would recommend using grade 8 bolts, but grade 5 is acceptable and the amount of bolts you will need will depend on how you plan on mounting the coupler. I would recommend using the bolt holes on the side of the coupler to mount to your trailer. I spoke with my contact for Bulldog and he said you...

  • Trailer Coupler Solution for a 30 Degree Trailer Frame
  • All of the A-frame couplers we sell are designed to fit 50 degree frames. As long as you, or the person doing the welding, is a qualified welder who knows what they are doing you could use the # BD44150WH301 on your trailer and then have wedges used so that the angle of the trailer and coupler match up.

Based on the picture you submitted this coupler should work as a replacement since Fulton and Bulldog are sister companies.

We do have A-frame couplers that bolt on, like # BD44150WH301 and others shown on the linked page, but none of these is a sleeve lock type. Drilling the coupler to allow bolt-on installation could result in a reduced capacity. The trouble is that there is no way to know exactly what effect drilling has without actually testing the coupler. The part has never been tested in this way and so you would be...

  • Adding Different Bolt-On A-Frame Trailer Coupler to Rusted Trailer in the Woods
  • Well, that is a coupler, though it is in bad shape. It is a bottom mount or underslung coupler like # CA-5335-B. You can check the ball cavity to see if it is in working order but all that corrosion makes me think that using its coupler is not going to work. In order to use a regular coupler you will likely have to cut off that bottom mount coupler so a new coupler will be able to be lowered on the ball. The jack will also have to come out to be able to install a new coupler. As long...

  • Is Bulldog Heavy-Duty Cast Head Coupler Made of Cast Iron?
  • The Bulldog Heavy-Duty Cast Head Coupler # BD44150WH301 is actually made out of cast steel. It also has a zinc finish in order to protect it from corrosion. This coupler has an A-frame design and mounts to a 50-degree trailer tongue. I've added a link to a video review of this product for you to take a look at.

  • Bulldog Heavy-Duty Cast Head A-Frame 2-5/16-Inch Coupler # BD44150WH301 is intended for standard 50-degree a-frame trailer frames. This unit is a bolt-on item and its rated 15,000-lb capacity is based on it being installed using all mounting holes to evenly distribute forces. If you were to use only 8 of the 10 mounting holes there would be some undetermined loss of capacity. It is not possible to exactly predict this drop in weight capacity. I recommend drilling the additional holes, or...

  • A-Frame Trailer Coupler that Can be Bolted Onto a Trailer
  • Bulldog A-frame trailer coupler # BD43805W0317 does not have holes on the side because it is a weld-on coupler. Coupler # BD44150WH301 can be bolted on but it is for a 2-5/16 inch ball, not a 2 inch ball like # BD43805W0317. All of the other A-frame couplers we have are weld-on applications. If you go with a weld-on coupler the welding will need to be performed by a qualified professional welder.

  • Mounting Hole Spacing of Bulldog A-Frame Coupler
  • The Bulldog Heavy-Duty Cast Head Coupler # BD44150WH301 has the same standard mounting hole dimensions as the Demco DM13205-52 that are 1-1/4 inches from the top. You said you believe yours are 1-1/2 inches so if you are going to replace the coupler I recommend taking it off and double-checking; you may find that the holes are 1-1/4 inches. Otherwise there are weld-on options available that you may want to consider; I've added a link to our selection of A-Frame couplers that use a 2-5/16"...

The link provided will show you each of these 15,000-lb-rated wedge latch couplers from Bulldog.

  • Recommended Trailer Jack to Use with Bulldog Heavy-Duty Cast Head Coupler # BD44150WH301
  • I do have a solution for you, however the Bulldog Square A-Frame Jack # BD195322 referenced in your question will not work well with the Bulldog Heavy-Duty Cast Head Coupler # BD44150WH301. This is because this particular coupler features a 2-1/4 inch diameter hole that is designed to accept round tube trailer jacks, not a square design like the Bulldog model you mentioned. For this coupler, I instead recommend looking at the Bulldog Round A-Frame Jack # BD1550101344. This is another...

This ball mount is about 6 inches longer than most Convert-A-Ball ball mounts. Since I'm not sure what amount of rise or drop you need, I've attached a link to all...
