Pricey and shipping was extra expensive, but these are heavy duty and work well.

    • Fantastic Tool
Size: 4x4 Painted
I've been a professional remodeler for decades, but only discovered these a year or so ago. They are, without a doubt, one of the most useful tools I've ever bought. We keep 4 of them in the tool van and they come out all the time for shoring and light/medium structural jacking. You don't have to have 4x4's, just grab a couple 2x4's the length you need, screw them together and you are good to go. A 2-3' iron bar is good for turning the bottom (the one Jet sells to go with their screw jacks works well). No more trying to find steel jack posts, that only have a range of a few inches, the right size. No more endless cribbing - if you need another height, just cut another pair of 2x4's. I know, they are stamped made in China, but some good old American ingenuity designed these. They are not cheap junk. I have supported, moved, and straightened a lot of residential framing with these in a short amount of time. If you work on removing and modifying bearing walls (adding headers or beams), beefing up floor systems, rebuilding old porches, etc. YOU NEED THESE. Best thing for structural remodeling since the LVL. ... show more

    • Works great 👍
Size: 4x4 Painted
I used this jack to replace the posts on my front porch, very easy to use and very strong, might want to grease the threads before you use it and cut a short 2×4 for leverage. Well made, fits on a 4x4 nicely.

    • Works well
Size: 4x4 Painted
I don’t know if this post jack is really worth $40.00 more than the competitors jack but it works well I just wish Amazon prime had free shipping (not free when you pay for your membership) so here’s to your ten million dollar yaut Jeff.

    • Sturdy and Secure
Size: 4x4 Galvanized
I bought an old house that is on a hill. It is supported with posts / beams with the posts resting on pier blocks. This summer I went through and replaced many of the pier blocks with diamond piers to stabilize the house and prevent it from sliding down the hill. I bought four of these screw jacks and can't be happier with how much easier they are to use than a car jack for this project. The stability of these screw jacks is amazing as one side slides into the screw jack and the other side can be nailed or screwed in place. I am really glad I purchased them for this project. ... show more

I like the fact that they fit perfectly for what I needed. I also like the fact that they were self-leveling. If I had one dislike I'd say they're steep on the price.

Worked great for my purpose. I needed to raise my porch roof just slightly to replace temporary supports and install cedar beams. Easy to use and had no problem with the weight. Highly recommend.
