Rated 4.3 out of 5 by 19 reviewers.
Rated 4.0 out of 5.0 by Effective product The jack post is used to help support the floor above the crawl space in a rustic cabin in the Adirondacks. After I figured out that reversing one of the two telescoping tubes gives additional length flexibility it was easy to install. It is probably loaded much below its rated capacity - it seems to be doing the job. I would buy it again. July 7, 2015
Rated 4.0 out of 5.0 by Easy to use but height adjustments are limited The jack is easy to assemble and adjust, seemed very solid although I used it on a relatively small job (jacking up a play structure that probably weighs 1,000 pounds). The main issue is that they provide you a height range that it can lift which I assumed meant it covered all heights in between. But it has dead spots - for my purpose there was about a 7 inch dead spot that was falling right where I needed it. So I had to keep adjusting by adding different height boards on the uneven ground to make this work. It worked fine but if you don't have the flexibility to make those adjustments this product may not work for you. If I had a much heavier lift I would have been nervous stacking various boards under the jack. July 7, 2015
Rated 4.0 out of 5.0 by good value but I would change the design a bit Sturdy construction and good value. For my application, I would have liked the end plates to fasten to the jack in a positive fashion. The current design provides alignment but relies on the pressure to hold the jack in place.

Rated 5.0 out of 5.0 by 4 Ft. 7 In. Super "S" Series Jack Post Excellent Product! Three of these jackposts long with an 8' length of 4X6 structual lumber made easy work of correcting a kitchen floor that was settling unevenly due to newer, heavier appliances. The threaded fittings are extremely strong yet allow for fine-tuning of height adjustment. Simple to use, built to last, it's the perfect solution for what could become a serious condition.

Rated 5.0 out of 5.0 by Excellent jack post I brought this 3 jack post for crawl space to support the beams. They are every easy to install and no complicate at all. Also, good price for these items than order directly are bit expensive than this. June 23, 2015
Rated 4.0 out of 5.0 by Good Product but Manufacturer Needs Better Quality Control The jack posts meet my requirements for the purpose I purchased them for, but when I went to install the last one of the three jacks I purchased I found that there were metal spurs in the threading of the bolt that screws into the post to adjust the jack. I could possibly have used a file to remove these spurs, but did not want to void any return warranty options by altering the product myself. Therefore I had to decide whether to return the product and not finish my project because I had to wait for a replacement, or make a trip to a local Home Depot store and see if they could resolve the issue. Luckily there was a tool rental section in the location closest to me and they filed off the spurs and the jack was then useable. My point being, I should not have had to make that trip to a store when I ordered online AND that if this particular manufacturer would have check it before it left his plant that would not have been necessary.

Rated 4.0 out of 5.0 by Tiger Brand steel jackpost I had a problem with a wood deck that settled 6 inches off-level (downhill slope). The jackposts (3) were used to gradually bring the deck back to level. The adjustable bolts proved easy and precise to use to ease the deck back in position. For safety I attached the steel mounting plates to the overhead wood joists and slipped the jackposts in position (no wobbling / unsteady feeling). Jackposts are available for rent $12 each a day, it made no sense to rent when Home Depot could deliver them to my doorstep (and own them) for such a reasonable price. May 28, 2006
Rated 5.0 out of 5.0 by Great for crawl spaces It is as described and really works well in crawl spaces. Our crawl space is just above 4'. I like the design as well. February 11, 2014
