Video Transcript for Bulldog Round A-Frame Jack with Caster Review

Speaker 1: Today we're going to be taking a look at the Bulldog Round A-Frame Jack with caster. This is a top-wind jack. Part number is BD155300.This A-frame trailer jack has a 1000-lb. lift capacity. Customers will like that it includes a caster. The caster's going to make it easier to maneuver your trailer.

The caster is removable for while you're on the road.Customers wonder what the difference is between a top-wind and a side-wind jack is. It's really just a clearance issue. You want to be sure and choose which one works best for your application.The crank has an 8-inch radius. You'll need at least that much for clearance. At its lowest height, it offers 12 inches of lift.

At its highest point, it has 27 inches of lift. That gives you 15 inches of adjustability. It measures 19 inches from the plate to the top of the jack.It's a dependable jack that is recognized as industry standard by the American Society of Agricultural and Biological Engineers. That means it's been tested to high standards for agricultural and commercial use.E-Trailer experts are recommending this jack for use on pop-up campers, smaller traditional campers, and boat trailers as well as utility trailers. Customers on our site are comparing this jack to the Dutton-Lainson A-frame trailer jack, part number DL22530.

They both have 1000-lb. weight capacity with a 15-inch lift. The Dutton-Lainson, however, is a side-wind jack and offers a natural metal look with a zinc plating for corrosion resistance. The Bulldog jack has a gray-painted finish, so you may want to avoid saltwater applications. The Bulldog also includes a caster, whereas the Dutton-Lainson does not.Now that we've gone over the features, I'll go ahead and show you how to get it installed.

I've already gone ahead and removed my trailer's old jack. You want to be sure and support your trailer's A-frame with a floor jack or your vehicle's hitch. Now, it doesn't come with any hardware, so you will have to provide your own. To make it easier, you can just reuse your old hardware.First step is to remove our caster, so we'll remove the pin and then it just slides right off. Now let's go ahead and install it. It's a standard A-frame design, so it should line up with your existing holes. Perfect. Then we can take our hardware. I'm going to loosely install all the bolts, and then I'll tighten them down. Now we can reinstall our caster, and then we're all set. Once it's all the way down, it raises up, and remove our floor jack.That's going to complete our look at the Bulldog round A-frame jack with caster, part number BD155300.

Do you have a question about this Trailer Jack?

  • Weight Distribution Solution for A-Frame Trailer with Side Mounted Jack
  • Your picture is a bit grainy so I couldn't tell for sure, but if there is a hole in the center of the a-frame for mounting a jack you are going to want to install a jack there and remove your side mount jack. The part # BD155300 has a wheel caster like your current jack does as well. With the jack off of the side of the trailer you would have clearance to install a WD system. Since you already have sway control the Reese Trunnion system part # RP66540 would be a great choice for a...

  • Determining Correct Replacement A-Frame Trailer Jack for 1976 Shasta Camper
  • A-Frame trailer jacks such as the Bulldog Round # BD155300 referenced in your question will all have similar outer tube diameters, but not all will be exactly the same. To determine if this will work on your trailer, I recommend simply measuring the outer tube on your existing jack to see if this will match. The Bulldog Trailer Jack has an outer tube diameter of 2-1/4 inches. When choosing a new trailer jack, you will also want to make sure it has the needed capacity to lift the tongue...

  • Available Caster Wheel Trailer Jacks
  • The Fulton Wide-Track Wheel Assembly # F500266 is designed specifically to fit Fulton's F2 jack; it has a special tubing design that is not fully round so it will not work on other standard round tube jacks. The other jack wheels we offer are designed to fit jack tubing of 2-inch or 1-3/4-inch outer diameter. Those caster wheels are shown on the linked page. I also linked our main page for wheeled jacks in case you want to install a whole new jack. You can click on the jack type at the...

  • Correct Trailer Tongue Jack Capacity for a Trailer with GVWR of 2980-lbs
  • When it comes to either trailer tires, hitches, winches or jacks, having extra capacity is a good idea. With jacks, using one rated for more weight than you're actually going to ask it to lift means it will have to work less hard to do its job. That tends to mean reduced wear and tear and can lead to a longer working lifespan for the jack. Since the cost difference between 1000-lb and 2000-lb jack is often quite small, it just makes sense to add safety margin whenever possible. For...

  • 1,000 lb Jack Recommendation for Boat Trailer with 2 inch Pipe Mount
  • The Bulldog Round, Pipe-Mount Swivel Jack - Sidewind - 15 inch Lift - 7,000 lbs, item # BD198250, has a male pipe on the jack and a female receiver that welds to the trailer. This female receiver has an inside diameter of just over 2-1/2 inches to fit on the 2-1/2 inch male pipe welded to the jack. This jack utilizes a 5/8 inch pin to secure the jack to the trailer. For a jack with a 2 inch outside diameter male receiver that welds to the trailer frame and has a capacity of 5,000 pounds,...

  • Wedge Style Coupler and A-Frame Jack that Fits Circle J Horse Trailer
  • The style of coupler you have now on your horse trailer is a Bulldog Collar Lok style which is very common on horse trailers. The Bulldog Wedge Latch Coupler part # BD44150W0317 will fit perfectly on your trailer as thankfully the angles of the couplers and trailer A-frames were all made to the same angle. This means that after you cut off your old coupler this one can easily install in place of it and will work great. For a topwind jack like you have that will fit the new coupler and...

  • Can Bolt-On Trailer Jack be Installed on Round Tube Trailer Frame
  • It sounds like you have a bolt-on trailer jack and unfortunately there aren't any bolt-on jacks that are designed to fit round tube trailer frames. This is because this type of connection would allow for too much movement on the frame, especially when it's under load. Your only option is to use a weld-on type jack such as the Pro Series # PS1401440303 that includes the pipe mount that would be welded to the trailer frame. This particular jack features a 5,000 pound lift capacity with...

  • Sounds like you have a trailer jack on your trailer and you are looking for a wheel caster that will fit it. Or maybe you are looking for a new jack for your trailer.
