Video Transcript for etrailer Round A-Frame Trailer Jack Review

Today we're going to take a look at the round a-frame trailer jack, part number TJA-5000-B. This is what our jack looks like when it's installed in a typical application. Start at the top with our handle here. You'll notice that the handle itself has a zinc plate coating to help protect the metal. Also, for protection, our entire jack body has a power coat finish to it. One neat little detail we really liked about this jack is that there's a nut and bolt assembly holding the handle on.

Compared to some other brands that are out there who just use a simple rivet, when the time comes when you need to replace your handle, it can be a real hassle to go ahead and get rid of the old rivet. It may be easier just to replace the whole jack. With this one, the simple nut and bolt assembly, you put a new handle on and be ready to go in just a few minutes. Let's take a look at the bottom of our jack. You notice there's nothing on the bottom there. You can actually add a couple accessories.

For a foot plate to the bottom of this one, you could use part number JF-99, and also, you can add a caster to the bottom of your jack such as part number JC-102. Now I'll go ahead and cover the operation of our jack. It's pretty simple. This is our tip wind style. We rotate it clockwise, it extends the jack and raises the trailer up and then to retract it we go counterclockwise.

Now our jack provides 14 and 1/8 of an inch of lift, so this is what the jack looks like when it's fully retracted and then we'll go ahead and extend it down to its maximum length. A properly installed jack right here will have 5,000 pounds of support capacity, however, one little note here that it'll have 3,000 pounds of lift capacity. This is a very simple jack to install. Couple things to know that this is designed to work with a variety of A-frame couplers that are out there and just double check, you want to makes sure that your opening's about two and a quarter inches. Simple to install our jack. In fact you may have more trouble removing the old jack before you put the new one in.

Go ahead and put it into place, rotate it so the holes line up and then you can install your hardware. Our jack does not come with any hardware to install, you have to provide that. The hardware we're going to use will be a grade five 3/8 bolt, a couple of washers and a lock nut. With this size hardware, typically you'll need a 9/16 socket and a wrench. With that, it only takes a few moments to install your new jack. Now finished with the round A-frame trailer jack, part number TJA-5000-B.

Ask the Experts about this etrailer Trailer Jack

  • Jack With Short Retracted Height for Horse Trailer
    The # TJA-5000-B jack has a 10-3/8" retracted height without a footplate so for a 5,000 lb jack with less retracted height, a great option is the Rack'em B-52 Round A-Frame Trailer Jack # RA-29. This jack has just an 8-1/2" retracted height and if you add the Bulldog Detachable Footplate # BD018564 you will be adding less than half an inch to that. If you needed even less height you would need to get a jack that does not have as much lift capacity. The lift capacity only needs to...

  • Recommendation for Economic A-Frame Trailer Jack with 3 Hole Mounting Plate
    For your trailer, I recommend the etrailer.com Round A-Frame Trailer Jack # TJA-5000-B. This economically priced A-Frame jack features a lift capacity of 3,000 pounds and a static capacity of 5,000 pounds. You will just want to make sure this is sufficient for the tongue weight of your trailer. It will give you a total travel of 14-1/8 inches. It does have a 3 hole mounting bracket and an outer tube diameter of 2-1/4 inches. I have attached a short video demonstration on this product...

  • Does etrailer Drop Leg Fit 5,000 Pound Sidewind Jack
    The drop leg # JF-1005H-Z fits 2,000 pound etrailer and Ram jacks as well as topwind 5,000 pound jacks, like part # TJA-5000-B but it doesn't fit the 5,000 pound sidewind jacks like # TJA-5000S-B. The inner tube on the 5k sidewind jacks have a thicker inner tube that doesn't allow the leg to slide up inside.

  • What is the Lift Capacity of the etrailer.com Square A-Frame Jack # TJDA-5000S
    The lifting capacity of this jack is determined by the drop leg. In this case the Drop Leg # TJD-5000-FT that comes on the # TJDA-5000S jack is rated for a 3,000 lb lift capacity. If you are needing a trailer jack that has a 5,000 lb lift capacity then I recommend the Round A-Frame Trailer Jack # TJA-5000-B. There is a drop leg that you can purchase for this jack as well. The Drop Leg # JF-1005H-Z will give you a little more surface area for your trailer jack to use.
