Sturdy and Secure
I bought an old house that is on a hill. It is supported with posts / beams with the posts resting on pier blocks. This summer I went through and replaced many of the pier blocks with diamond piers to stabilize the house and prevent it from sliding down the hill. I bought four of these screw jacks and can't be happier with how much easier they are to use than a car jack for this project. The stability of these screw jacks is amazing as one side slides into the screw jack and the other side can be nailed or screwed in place. I am really glad I purchased them for this project.

Does the job Well!
I just installed them today. They went in real easy & work perfectly. We'll see how they stand up to a few northern Ontario winters - that'll be the real test. A little pricey by the time I got them between exchange/shipping/import duties... They wound up being over 100$ each.

Weird raising crank
It works, but turning the crank to raise the device is awkward when under weight.
