This is a must-have for anyone who owns a shipping container or Conex box...coupled with a bottle jack, it makes leveling them a breeze
Make sure the base of the bottle jack you are using is WIDE!!! Nothing wrong with this product, in fact, it worked very well.
This worked great on leveling out my shipping container. It locks in nicely for me to jack the container up to rebuild my concrete block piers. I didn't know that they even made these things to be able to lift these containers properly. Overall, it made the job so much easier and safer.
It works like a charm! Easy to use and it works.
