I installed two of these in my crawl space to correct sagging beams. I set down a solid piece of concrete (4"x8"x16") flat, with a 4"x4"x16" piece of treated wood flat on the concrete. Then I installed the jack the screw end down. This required several small adjustments (after the jack was tightened just snug enough to keep it from falling) to get it plum. I then nailed the plate at the top to the beam and the plate at the bottom to the horizontal 4x4 wood (atop the solid concrete block.) With this arrangement, I did not have the problem outlined by ScottC (earlier post.) The approximately 3" diameter of the jack tube at the top pressed nicely against the double timber beam and the screw at the bottom pressed against the metal plate secured to the 4x4 wood. I noticed no warping of the plate as I turned the screw to tighten up the jack until I heard the beam respond a little. I will give 1/2 turn a month.

I ripped out my old master bath fiberglass shower unit and replaced it with a cement mud bed river rock floor, porcelain tile walls and a heavy frame-less glass door. This increased the floor load significantly so I thought some extra support would be a good idea.
I ordered these jack posts from HD and they arrived in a timely manner. These are not a piece of precision equipment so they are a little rough around the edges but more than adequate for their purpose. The packaging is not tight so the parts bang around during shipping. This caused the threads on the screw posts to get dinged up but they can be easily cleaned up with a small file or thread restore tool, I would plan on having to do this. The top and bottom plates are not attached to the posts but could be tack welded if you need firm attachment. My install was nearly plum and I used cement piers with nailing blocks and a 4x4 top support to nail into, so free floating plates were not a problem. I was able to do the install by myself and the bathroom floor feels much more stable now. I would recommend this product if you need similar floor support.

Rated 4.0 out of 5.0 by fnprice Good for holding, not as much for lifting
These didn't have the lifting power to correct the sag in the floor of our single story wood frame house. I had to get a bottle jack to lift and then used these to hold a beam in place while I built piers for permanent support. They worked fine for this.

Rated 1.0 out of 5.0 by wilbur Not at all what I expected
The are basically two pipes that fit into each other with two metal plates you must balance them on put together with nuts and bolts. The two plates do not attach, you have to keep the pipes balanced on them until you can screw a top nut all the way to hold them tight from top to bottom. This may not make sense since you don't own one yet, but bottom line for me is to stay away from these. I could not use them. I needed something to help me work alone, some extra hands, and these just made things more difficult for me. Not good.

This is a well designed, easy to use, product. i used 2 of these jacks to jack up a 10 x 10 cabin in the woods that had settled 1" on one side last winter. The cabin is 2 x 4, 1/2 inch plywood, and pine siding…so it is not that light! These jacks raised it and now it's level again. For the money, a great buy.

Rated 4.0 out of 5.0 by Andy Did the job at a reasonable price.
Used to replace a hidden lower section of a wood porch post which had rotted. Easy to assemble and use, although the upper pad is not attached (just held in place by pressure). Should be a more permanent fix than using wood would have been, and is adjustable if necessary. Much easier and cheaper than replacing the entire wood post would have been.

This unit is intended to correct sagging floors. It was easy to assemble and use. It consists of two metal sleeves that fit one inside the other that are held in place by 2 bolts that set the coarse length. A jackscrew then fits into the top of the unit for fine adjustment. I chose the smallest model that adjusts from 19" to 36", as it had to fit in a crawl space. I wished that the unit could adjust to less than 19" as it barely fit at its minimum length. The minimum length is actually about 19 1/2". The unit needs pliers or a wrench to adjust the jackscrew, but my pipe wrench was too thick to grasp the flats on the adjustment shaft. I had to use a smaller pliers to adjust it. The jaws of the pliers or wrench should be less than 1/2" thick. The unit is supllied with top and bottom mounting plates that are meant to be secured to the joist and floor of the structure using wood screws (not supplied). But as my crawl space has a concrete floor, I did not use the bottom plate. The manufacturer recommends gradual adjustment, about 1/2 turn per week. So far it has corrected a sagging floor in my house, and doors that failed to latch because the frames had parallellogrammed now close properly.
