Rated 4.2 out of 5 by 108 reviewers.
Rated 5.0 out of 5.0 by Posted up, taking a load off... As a state licensed builder, I find this product simple to install with easy directions (pay attention to whether it is used to support metal or wood), and it simply handles it's business. Secure and solid, it holds up no matter how many times I bash into it (funny how the places you need these for are always in the most inconvenient places, i.e. The middle of my basement wood shop). Even comes painted up with scratch resistant durable paint (which is code in my state when used in a basement) which saves me the hassle when I need to install them. February 18, 2014
Rated 5.0 out of 5.0 by Product works as designed The Jack Posts supported my concrete porch floor while replacing the foundation walls. March 18, 2014
Rated 5.0 out of 5.0 by Did the job just fine I followed the earlier suggestion to buy using store delivery to make sure all the parts were included. Sure enough, one of the boxes was open - but fortunately everything was there. Plates are a little flimsy - they bend quite a bit under load and the shaft really grinds into it when it turns. I found it helped a lot to us a very good lube - like super lube- on the threads and also on the bottom plate. I added a heavy 1/2" washer beneath the shaft where it turns on the plate - with superlube on both sides. With this I was able to turn the jack with a 12" crescent wrench with no problem.

Rated 5.0 out of 5.0 by Holds a heavy load,easy to use We used the jackpost to hold the porch roof up while ,replacing the floor and the old post . It was easy to put the Jackpost in place next to an old post and lift the weight of the roof up so the old post could be easily removed. We raised the jackpost with a wrench August 21, 2013
Rated 5.0 out of 5.0 by Easy to setup, east to adjust to various heights and THEY WORK Used the jack post to support ceiling joist to replace a 21 foot long, 3 1/2 " wide and 16" deep support beam in house. "Tiger" jack post were easy and fast to set up. They worked great and the price was right. July 31, 2013
Rated 5.0 out of 5.0 by Did Exactly What I Wanted This product was less expensive than renting from the local rental shop. They (2) held up my patio overhang while I replaced the 4x6 posts. Simple, quick and safe. June 2, 2012
Rated 5.0 out of 5.0 by Very useful The jack post was used in conjunction with other jacks to raise a ceiling from within a house before placing a new support beam in place. I was able to raise the interior ceiling 1.5 inches where it had sagged over the years. I accomplished this with no damage to the sheet rock textured ceiling. December 10, 2014
Rated 1.0 out of 5.0 by Missing Parts Ordered 4 of these. 2 of the 4 were missing parts and were unusable. This is super frustrating. September 29, 2015
