  • Does the job.
Size: 54-150 Inch (1 PACK)
They arrived on time. Sturdy, heavy, easy to use and did the job that I needed done. They are temporary support for our deck while we replace some rotted wooden suppirts.

  • Quality Reeks
Size: 16 in, 3 pack
I bought a set of 3 for under my 50 year old house to sturdy up the flooring. After paying a foundation specialist company $5000 for leveling and bracing the main floor beam with their jacks, I decided to brace the center under the living room floor with my own jacks. These Bob's foundation jacks are just as good as the ones the foundation company used. I just want sturdy support, I'm not using them to raise the floor. I looked at other jacks and I believe these are money well spent ... show more

  • Well-made and affordable
Size: 19-36 Inch (4 PACK)
I have an older house that's 60 years old and needed the floors raised as they had settled about three inches over time. A local company quoted me over $10K to do the job and after some official YouTube research I decided to take a swing at it myself and save some $. I bought 4 of these and hired some local contractors for $2K and 3 days later My house is dead level. I made sure everything was done properly with poured footers and after all was said and done the project was done for 1/4th of the price. ... show more

  • Work Great for Elevated Cabin
Size: 19-36 Inch (6 PACK)
We built a cabin inside a shed frame and didn’t think through the beams very well. We had three 2x4’s spanning 8 feet as beams. Ok for a shed maybe but definitely not for a finished cabin. We used these jacks between the poles to cut the span of the beams in half and are very happy. Have been able to take sag out of the beams with them. Very happy and they’ll stay in place permanently. ... show more

  • Good quality jacks,
Size: 54-150 Inch (2 PACK)
These are thick gauge steel, something you want when supporting a deck or beam when repairing. Read the directions!! Understand that improper use will get you hurt or worse. Don't go cheep when your life is at stake. If your saying "the should hold it" add another jack. More is better. I'm actually buying more as my family wants to use them too. Great value & quality product. I'll put my life on it... ... show more
