How many house jacks are needed? The number of jack posts you need depends on what needs to be supported, how heavy it is, and how big of an area is being supported.

Two Jack stands used too support saging steps
Size: 2PC(31"-63") Color: Orange
I purchased two of the jack post to help hold up a set of steeps that were saging. They completely fix my problem. The are built of very strong material and are easy to adjust and put into the required space.

Big enough for the job, small enough to fit
I have a live floor under the dining room china cabinet, which allows the china to rattle whenever anyone walks across the room. I thought it might help to brace the floor from the crawl space (photo). Access to the crawl space limited my choice of materials, so I got some strut channels to support and frame the jacks. It was convenient to space the channels just slightly apart so I could use strut nuts to secure the jacks. Works well. The only thing I'd like is to have the handle a few inches longer so I could exert more torque in lifting the overhead beams. ... show more

stable support for garage storage racks
Size: 2PC(31"-63") Color: Black
These were used to support a cracked wooden support in an existing garage storage rack. The adjustability and stability are excellent.

Jack or support
Size: 19-38 inches / 2 Pack Color: Orange
I bought these because I thought they would be helpful in raising a sagging beam. However, when I put a load on them, I couldn't screw them up. There is no bushing in the top plate, so when I put weight on them the top plate locks down and turns. It will turn itself off the object that you are trying to raise. So, I had to use an automotive jack to raise the beam and use the floor jack as a backup support. So, in my opinion, they are not jacks but strictly good for support once the beam is in place. ... show more
