NBJINGYI adjustable drop leg for trailer jack Stand extension Drop Leg with 1.75 inch ID for Jacks Foot Jack Camper Accessories

The unit looked good especially for the price so I left 5 stars. Unfortunately it did NOT fit my power tongue jack Atwood Mobile MPD 71119 PC-44F-1001 E186696. Leaving this review to possibly help out the next person with an Atwood jack.

I rolled the dice on this cause I really wanted the wider round foot for my trailer jack. I knew from the other reviews that I might have trouble getting it in the post. I got lucky, it slid in, but was very tight. I had to grease up the tube and hammer it in there. It will never slide up and down for casual height adjustment. So if you're looking for more of a permanent install and if fits, you'll probably be happy with this. (Trailer was a standard cargo trailer, not a camper.)

I'll start with the good part: the jack leg seems sturdy and well built with a nice finish.Bad: it doesn't fit. Not only does it not fit my brand new jack leg, it also does not fit my old jack leg or any jack leg that I tried at local auto parts stores. It seems like they manufactured it about 1/16 - 1/8" too large. It ALMOST fits into numerous lack legs, but not quite. It's simply a hair oversized and therefore doesn't fit.

This part was just what I wanted. Sadly, it was just a little too large to fit inside the post on my trailer jack. Five stars for the easy return.

It was slightly too big to fit inside the factory hand-crank jack stand on a 2016 Jayco Jayfeather. It's too bad because it would have been super convenient to have. Ended up getting a 9" and 15" jack stand extender because I don't trust stacked pieces of wood.Update: I have since upgraded to a 2022 Keystone Bullet with a Lippert electric jack stand. Upon inspection of the jack to see if this would work on that, I noticed there is a metal lip that runs the entire inside of the Lippert electric jack stand, so there is no way it will work for that one either.

Thankfully I read the reviews and knew what to expect with this device. Ordered a used (good) from Amazon option which I assume was a return due to not fitting as expected. Since it was a well discounted item, I took the chance to make it work. Interior of curt jack that I purchased to use this with required a good amount of cleaning up of the rear weld seam to allow for it to fit (very tight at that time) at all. Then a GOOD DEAL of work with the old angle grinder and wheel along all sides of this insert made for a PERFECT fit. A little bit of work, a worn out grinding wheel and about an hours worth of work but in the end, this works quite well in my trailer jack and does exactly what I hoped it would.

This didn't fit my application, and I neglected to check it before the return date expired. My bad. It's very well-built, so I still give it 5 stars. Just make sure it fits your trailer when you receive it.

I was not able to test fit this prior to reaching the return date, missed it by one day. This really looks well made and would be a great product, but for a design flaw which made it difficult to install and use. The issue is the groove on this extension appears to be the same profile as the groove on the exterior of the trailer jack instead of the interior which of course would be slightly wider due to the material thickness. In other words, the groove is to narrow and binds slightly when installing it. I confirmed this by applying grease around the extension and observing the binding points.I had to force the extension into the trailer jack and likewise have to use a long piece of wood, I used a 2"x2", and hammered it back out. I did this a few times hoping that it would slide freely, but with only limited success.This appears to be a design flaw, however I cannot say that this would be the same for all trailer jacks and it may work just fine. These should drop down when you remove the pin, but in my case I have to force up and down.I would like to return, but as I mentioned missed the return date by one day.
