I utilized these as the base to build my hot tub deck. Super easy to use and super strong. Makes installing a deck on un-even terrain pure simplicity.
Very easy to adjust, just build your frame, then just turn the knobs until the base of the deck is level, then just put on the top boards and you’re done.
These just work and makes deck building easy. I built a 10×10 in under an hour and a half. Highly recommend.

Used two of these on new foundation piers to support one end of a garden shed that had settled. Had to lift the shed using hydraulic jack first. Used others under a deck at the front of my house to stabilize areas that had settled as well. Pretty easy to adjust the height, just keep the top and bottom pieces fixed and rotate the center disk.

We used these to build a level wood floor. I have a 20’x8′ studio/workshop area which I didn’t want to have a hard concrete floor which would aggravate my legs and pain in feet. So we left it gravel and used these adjustable blocks then put the 2x4s with 12″ center So easy to level everything then lay down plywood I showed them to my local hardware pro desk and he’s going to suggest they stick them I’d highly recommend these

We used these during a deck repair project that resulted in finding several rotting joists. We used these to replace some of the old posts, and they worked very well. They were easy to install and adjust for level support.

Worked perfect to install a floating deck over a sink patio slab and make even with the entry. Holds weight really well. I have a rain barrel where I put extra supports. Deck composite weighs about 1000lbs and is holding well.
