### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Cost-effective and quality jack - furniture application
  

*by C***M on Reviewed in the United States on October 8, 2024*

I needed a small jack to support the center of a very long couch which I raised with bed lifts. The center support leg wouldn’t reach the floor anymore and this turned out to be the perfect solution to extend the support leg. The thumb wheel to set jack height was adjustable while the couch was putting its load on the jack, which meant no additional time was spent measuring the gap and testing iteratively.

    they did what I needed them to do
  

*by C***R on Reviewed in the United States on April 27, 2023*

I bought a few sets of these things and they're real simple machinist jacks that could be made at home. My only complaint was that the threading on all but one of them was very loose. Also for such a small increment of movement it would have been a lot nicer if they were fine thread vs the course the manufacturer used. But they were cheap and did what I needed.
