Ellis Manufacturing Adjustable Mini Screw Jack Post – House Jack for Foundation, Floor Leveling, and Concrete Bracing – 15,000 lb Max Load Capacity – 2.5" Adjustment

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.

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.

Jack worked well as advertised

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

It’s a great lift but they sent it with out the bar to affect the turns.

These are great for lfting floor joists and live up to the hype. Highly recommend if you have a project like mine

Came quickly

Great product and quality.
