Video Transcript for etrailer Trailer Jack JF-101BK Review

Today, we're going to be looking at a footplate for round tube jacks. This foot plate's going to fit on your round tube jack, and it's going to help spread out the applied weight . especially on softer ground. It's going to help prevent sinking. And it's going to increase overall stability. It's made from a steel construction.

It's going to feature a nice clear, zinc finish, so it's going to be resistant to rusting, corrosion. The weight capacity is two thousand pounds. It does come with the pen and clip, that way you can secure it to the inner tube of the jack. There's going to be four pinholes on the tube here of the footplate. That way you can rotate it .. and you can have the foot plate facing whatever direction you want.

So, if you want it facing this direction . you have the pinholes that allow you to do that; and the other direction you have the pinholes that allow you to do that as well. The pinhole diameter is going to measure just over three-eighths of an inch. The actual diameter of the pin is three-eighths of an inch. Again, this is designed for round tube trailer jacks. It's going to fit, um, jacks that have an out tube diameter of two and one quarter inches with an inner tube diameter of two inches.

The inner tube is going to fit inside the tube here on the foot plate, and it's going to secure with the included pin and clip. I do want to point out that inside the tube there's going to be some stops in there. That's going to prevent the inner tube of the jack from going down further into the tube. The distance that we have from the top of one of those stops to the center of the pinhole is going to measure one inch. So you want to make sure that from the bottom of the inner tube on your jack to the center of the pinhole in the inner tube you have about that one inch measurement, and that's going to let you know if that's going to work for your application or not. Taking a look at the foot plate dimensions, measuring this direction first. This is going to give us a length measurement of about six and one quarter inches.

Going this direction, we're looking at about four and a half inches. The overall height . that's going to give us a measurement of about eight and three quarters of an inch. And then the actual extension that this is going to add to your jack, we can tell that by measuring from the bottom of the foot plate to the center of the pinhole, because that's our attachment point to the jack. That's going to be about seven and fifteen-sixteenths of an inch. That's going to do it for today's look at the foot plate for round tube jacks.

Was delivered earlier than I thought it would This was a replacement of the original part ,but is built heavier than the original which is great. Ordered the pad and wheel adapters which work awesome. Have bought items from etrailer before and very satisfied with their service and product. 690559

- JF-101BK

This product was recommended to me by etrailer customer service staff after I told them what I was looking for and after giving them the diameter of my trailer jack. Unfortunately, it did not fit. I had to take it to a shop that did custom exhausts to have the upper tube expanded which cost me an additional $10. Needless to say, I'm not happy with my experience with etrailer. 674817

Quality build. Fit perfectly. 661639

Well made product. The foot appears to be able to hold water from rain and cause rust...so I may drill drain holes in it. 589047

Ask the Experts about this etrailer Accessories and Parts

  • Can Ultimate A-Frame Trailer Jack 322-RDJ-2K Be Completely Removed from Collar Assembly
    Yes, the Ultimate A-Frame Trailer Jack # 322-RDJ-2K uses a separate trailer-mounted A-frame collar that allows complete removal of the jack tube from the collar. Please note that the jack ships with a black plastic wedge that is held in place with a small retaining bolt. If this bolt and wedge are removed from the jack then the entire jack can be lifted up and out of the collar to give you the clearance you need for opening the rear door on your Jeep. Please refer to the linked photo...

  • Size of Footplate or Caster With Wheel That Fits Ultimate Trailer Jack A-Frame Jack
    You can add either a footplate or caster to the Ultimate Trailer Jack # 322-RDJ-2K. This jack has a 2-1/4" outer tube and 2" inner tube and the correct footplate is # JF-101BK while for a caster with wheel assembly # JC-102 is a fit and attaches to the inner jack tube. I've added links to video reviews of each of these parts for you to take a look at.

  • Trailer Jack that Doesnt Hang Down Very Far for a Big Tex Utility Trailer
    Depending on the capacity you need I do have some A-Frame jack options you might like. Take a look at the Ultimate Trailer Jack # 322-RDJ-2K. It is more adjustable than other jacks and measures just 1-3/4" from the mounting bracket to the bottom of the leg with the jack fully retracted and the collar at the lowest setting. This jack is rated for 2,000 pounds. A wheel or foot will add more to that 1-3/4 inches so keep that in mind. For a wheel you can use # JC-102. For a foot you can...

  • Mounting Plate Dimensions and Bolt Holes on Ultimate Trailer Jack # 322-RDJ-2K
    I went out to our warehouse to measure the Ultimate Trailer Jack # 322-RDJ-2K for you. The bolt holes are oval slots each having a 3 inch on center measurement. They range from 2-5/8 to 3-5/8 inches from the front of the coupler back and then the side to side holes range between 2-3/8 inches to 3-7/8 inches. The overall plate dimensions are 4-7/8 inches on the back and 4-5/8 inches on the sides from the coupler back. I've attached a photo to assist. You may also be interested...

  • What Is The Correct Footplate for the Ultimate Trailer Jack322-RDJ-2K

  • Can Tube of Ultimate Trailer Jack 322-RDJ-2K Be Completely Removed
    With the right tools and enough time a determined thief can steal almost anything. This is true for the inner tube of the Ultimate Trailer Jack # 322-RDJ-2K as well as the caster wheel # JC-102 or foot plate # JF-101BK that might be used with it. In order to remove the inner tube the black wedge shown in the linked photo would have to first be unbolted.

  • Ultimate Jack # 322-RDJ-2K Compatibility with 22 Foot Travel Trailer
    The Ultimate Trailer Jack # 322-RDJ-2K is rated for a tongue weight of 2,000 lbs. As long as your 22 foot travel trailer has a tongue weight less than that amount you will be fine to use this jack. Most trailers have a tongue weight that is 10-15% of the total trailer weight, so based on that your trailer could be up to 13,225 lbs total weight and you'd be good. This jack does not come with a foot plate, so I recommend # JF-101BK which is rated for up to that same 2,000 lbs and can...

  • Ultimate Trailer Jack # 322-RDJ-2K Pin Function and Security
    The Ultimate Trailer Jack # 322-RDJ-2K has the pin and holes in the outer tube assembly allowing the entire jack to be adjusted in 2 inch increments. The pin inserts the full 1/4 inch thickness of the outer tube and has a pin to keep the spring loaded pin mechanism from accidentally moving so you won't have the issue of trailer movement or a physical bump causing the jack to release under load. I've attached a video to further assist. This jack does not come with a footplate or wheel,...

  • Trailer Jack Recommendation with Best Under Trailer Ground Clearance
    I have a great solution for you. The Ultimate Trailer Jack # 322-RDJ-2K has an adjustable height outer tube that you can raise as high as needed to give you the best under trailer clearance. For a foot plate you'd then want the part # JF-101BK.

  • Can Electric Jack be Submerged in Water
    Electric jacks such as the Electric Jack w/ Footplate # EJ-3520-BBX should not be submerged in the water; they are resistant to rain but not being completely immersed under water. Instead you will want to go with a manual jack, such as the Ultimate Trailer Jack # 322-RDJ-2K which has a 2,000 lb capacity and 27-1/2 inches of lift. It would require either Footplate # JF-101BK or Wheel # JC-102. If you need more capacity but less lift there is the Bulldog # BD155032 which has a 5,000...

  • Can an A-Frame Trailer Jack Be Rotated for Clearance
    Yes, you can mount the Ultimate Trailer Jack part # 322-RDJ-2K so that the release pin faces outward instead of towards the trailer. All you need to do is rotate the jack until the mounting holes line up and the pin is pointed away from the trailer. This should in turn give you the clearance you are looking for. If you would like to add a foot pad to this jack then you can use part # JF-101BK which is a direct fit.
