J-S-36

Good item

I have purchased these two different times and am very pleased with how easy they are to use and how sturdy they are! We installed a wood stove in a home with a crawlspace and used these to shore up the floor for the extra weight.This round be be for another area that we want to install a very heavy piece of furniture. I like that they are so easy to install!

Easy to install is relative :) Put several of these under my kitchen center spine before a remodel as insurance as the original metal posts holding my floor up were rusting. Popped these on solid concrete blocks then screwed them to the joists and then screwed them to the blocks. Be sure and level the blocks and the posts. They feel plenty sturdy. You should probably use a bottle jack to raise the house as using the screws on the jack posts felt 'iffy' as you really had to crank on them to get movement. If you put several in - raise each a little at a time. In my case I was supporting rather than raising so it was a non-event. However once you get everything to the right height I think they would support a bunch of floor weight. I felt comfortable that I had saved a ton of money for an afternoons work and the results look very professional. My kitchen floor is rock solid with no creaks or groans. Great value for the money.

Simple to assemble, great value. Only part I wish was different is the top and bottom mounting plates. They do not attach to the post. The plates have a raised punch that the post sit over but not securely. The load is the only thing that holds them in place. The plates are drilled so you can lag them to the structure top and bottom but there is no positive attachment of the plates to the post.

Performed as described.

Product received was as ordered. It was easy to install and adjust. The paint on the post could have been better, but I repainted them as I was installing them in a crawl space. Also, I would recommend putting grease on the screw to make them easier to adjust.

These work great for augmenting support on a foundation that is starting to sag. It's not a perfect fix, but it definitely beats floors that are sagging to the extent that they are in danger of cracking.

I used this floor Jack to secure a 120 gallon fish tank that had one buckled on one side. I was able to secure it back to level in less than 20 minutes.
