Rated 4.3 out of 5 by 36 reviewers.
Rated 5.0 out of 5.0 by Good product 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. March 14, 2012
Rated 4.0 out of 5.0 by Quality Product 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. September 22, 2014
Rated 5.0 out of 5.0 by Porch Lift Just what was needed to lift our sagging Cement Porch. Placed a concrete block under it and secured a treated 2x6 board to the top and with a few cranks, everything is back to being level November 3, 2015
Rated 5.0 out of 5.0 by Jack Post Did the trick raising our deck so that a post could be re-placed. Saving it for other times it is needed. September 15, 2015
Rated 4.0 out of 5.0 by 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. September 17, 2013
Rated 4.0 out of 5.0 by super S series jack post 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. May 28, 2006
Rated 4.0 out of 5.0 by 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. December 18, 2013
