Question:

For this TJDDP-20000SP-F, the outer tube is 4 3/8, the inner is 4, what size is the leg? If you buy this jack and need a replacement leg later, is that available? Thanks. Steve

Hello Steve, thanks for reaching out. The leg on the etrailer Square Jack # TJDDP-20000SP-F is a 4" tube. You could maybe call is 3-15/16" if you want to get picky lol. I went to our warehouse and took a measurement and a picture for you.

The replacement leg is not a part that is available by itself sadly.

I hope this helps. Please let me know if there is anything else I can do.

Jesse, I am traveling and using my phone, so maybe that is why I can't see the picture that you took. So to clarify, are you saying there are only two legs/tubes (an outer 4 3/8", and an inner 4")? Is there a drop leg, too? If there is, what is that size? It can't be the same size as the inner leg/tube, correct? Thanks. Steve M.

@SteveM No Steve, its not your phone we are having issues/bugs with our pictures uploading to these answer pages here the last day or two. They are working on a fix but I can assure you it is nothing you are doing lol. There is a single inner tube the let attaches to. I will send the picture I took to you email.

@SteveM I just got done measuring the jack. The jack with handle weighs about 67 lbs. The diameter of bar the handle attaches to is 1". The drop leg is 3-5/8" wide and the holes are 2-1/2" apart on center. The drop leg is held in place by two pins that are operated by a spring loaded handle on the front of the jack.
