Video Transcript for Bulldog Trailer Jack BD500240 Review

Today we're going to be taking a look at the weld-on male pipe mount for trailer jacks. This works for many jack mount applications. This piece gets welded to the trailer frame and provides an attachment point for a pipe mount swivel jack. It's constructed of a raw steel construction. Again, it is a weld-on application. A few measurements to go over with you real quick starting with the outer diameter. Edge to edge it's going to measure two inches.

Inner diameter is going to measure about an inch and a half, which means that this is a quarter inch thick steel. Taking a look at the length measurement, that's going to give us a measurement of around two and one quarter inches. The pin holes, there's going to be four pin holes on this pipe. Those all have a diameter of five-eighths of an inch. From the center of one pin hole going to the edge of the mount is about three quarters of an inch.

From this edge of the mount to the center of that pin hole is about an inch and a half. That's going to do it for today's look at the weld-on male pipe mount for trailer jacks.

Weld-On Male Mount Kit for Bulldog Round Jack - BD500240

Average Customer Rating:  4.8 out of 5 stars   (21 Customer Reviews)

Replaces the male pipe mount for your Bulldog round jack (BD1701480317). Includes 1 male pipe mount.


Here are some pictures of what I used your product for. The splitter just had a fixed position stand and it is fairly heavy so it was difficult to hook to the ranger because the stand had to be removed first. Now I can just let it down to the hitch and with the wheel I can also move it around the shop without lifting it. We also put an extra mount on the back so the wood falling from the splitter would not damage it. Thanks for the good service,


Good product, as advertised. The customer service has been exceptional, especially from Odelia.


I ordered 2 of these mount adaptors so i could weld them on either side of the tounge of my car trailer , Sometimes your forced into a tight spot and the jack won't fit if the truck is turned too sharp , This allows me to swap my tounge jack to the other side , Quality is great , If i counted my time and the part it would cost me 3 times what it cost to get this part from you Keep up the good work , Ive bought alot of supplies from you and have never been disapointed Thanks Wally P


Worked well, welded easily and robust. Had to replace a mount that was damaged (from theft) but the jack was still good. Kudos to etrailer for offering just this part so I didn’t have to buy a whole new jack setup


My package arrived exactly as ordered and one day earlier than expected. E-trailer folks were very helpful and enabled me to make correct choices for my project. I was able to repair my trailer jack mount better than it was from the factory. i ended up spending one fourth as much as I would have without ettrailer's assistance. HIGHLY RECOMMENDED


Fast shipping and good price! Who could ask for more? Etrailer rocks!


Product was as pictured and just what I needed to complete the installation of the jack. Great service.

  • Replacement Swivel Jack with Pipe Mount for Snow Plow
    The Pro Series Round, Pipe-Mount Swivel Jack w/ Footplate - Sidewind - 10" Lift - 5,000 lbs # PS1401420303 has a 10-1/2 inch dimension from the center of the mount but is only 6-1/2 inches from the center of the mount to the top of the unit. This is the shortest length from base to mount. If you need clearance when not in use, I recommend inverting the jack. If you need that measurement for function, then I recommend resting your plow on something to allow the jack to swing into place...

  • Inner and Outer Tube Dimensions for Bulldog Trailer Jack # BD1701480317
    I went out to the warehouse to measure a Bulldog Round Jack, # BD1701480317. The outer tube diameter is 2-1/4 inches. The inner tube diameter is 2 inches. I used digital dial calipers to take the measurements. If you need a foot or a mounting solution for this jack, we have the Detachable Footplate, # BD018564, Mount Tube, # BDPG9810-00, and Weld-On Male Mount Kit, # BD500240.

  • What is Overall Height of etrailer Jack # TJP-2002S-B
    The overall height of the trailer jack # TJP-2002S-B is 21-3/4 inches when fully retracted. When the pipe mount # BD500240 is welded to the trailer the jack will basically be flush up against the trailer frame so there wouldn't be any clearance there. Now the body of the hitch would be more like 3-1/2 inches away from the frame of the trailer though so if that's the clearance you are looking for this would work to fit past your 1-1/2 inch supports.

  • How to Install a Swivel Jack on Trailer So that Cranks Parallel to the Vehicle Direction of Travel
    The reason the jack handle is put on the side of the jack is for a couple reasons. If it cranked the way you referenced it would potentially interfere with the frame of your trailer as it would crank across it, and it would be kind of awkward to crank the jack as you would have to swing the handle in across the trailer frame. Where it's at now the person cranking the jack has complete access to the full range of motion of the crank handle. This would be helpful when jacking a heavy trailer. With...
