I needed to add support to some floor joists in a tight crawl space. These worked just right. A bit expensive but good quality and they don’t loosen up.

Perfect range of adjustment 6"-9", very robust, capable of much more than the load I expect it will experience.

The Ellis mini screw jack is easy to use and supports seriously heavy loads. I have a prefab cottage in the backyard that, due to heavy rains, began to sink on one side…most of the foundation is on a concrete pad but I was forced to use gravel and flagstones on one end. The end supported by the flagstones dropped approximately two inches. Using the Ellis Jack I was able to raise the base and insert a series of paving stones. I then raised the other end to insure the cottage was level. Once done I left the Jack in place to insure the leveling was secure. Once these heavy rains cease I will make the permanent supports and remove the Jack. I highly recommend this product as it is solid and easy to use.
