12Pack Adjustable Deck Support Pedestal - Base Support for Floating Deck Platform, Adjusts 1-3/16" to 2-3/8", Black

I used these to build (replace) a 16x22 floating deck. I also supplemented the install with a few of my original posts that were still solid in concrete. I used pavers with these to get the deck level. They seem well made and unless you are parking a hot tub or a car on the deck, I don't see them failing. I have built over 15 decks in my life and I wanted to avoid using concrete and 4x4 posts this time. I was replacing a large deck that had rotted out after 19 years. The ground was already flat and level, so these were a great option. The adjustment is the key. If anything, buy extra to distribute the weight properly. Too few of them would definitely be a problem.I would absolutely use these for any size deck that is low to the ground. Level ground is key however.

Interesting item. I am in process of doing some deck repair and thought I would give them a try. I think I ordered a dozen and have used all but three of them. The ground underneath my deck is not at all level so adjustable seemed like a logical option. They worked out very well and in places that were lower, I simply put a block or paver beneath the adjustable one. They are very easy to install and not too expensive. Only time will tell how well they hold up, but they seem sturdy enough.

This is an ingenious idea! When laying out a deck and trying to get all of the pier blocks accurately level across the entire deck, then having to shim or precision, cut pieces can be a total nightmare. This makes life easy! Just lay out the deck and use these adjustable piers that only need to be within the adjustment range to function perfectly.

I’m using these to put a floating deck on a concrete pad and they are perfect because at the lowest setting it’s just barely off the ground. My only concern is when I walk on the frame I can actually see it unscrewing itself as I walk which could be a concern later down the road

Made a step down from our deck. These really helped with the leveling and made the job easy!

Work as expected, wonder how long they will last, not suer they how long they will last.

I recently built a very large shed and wanted to use a floating pier system as the ground was uneven and had compound slopes. I purchased a series of these in multiple sizes and they worked perfectly. Adjustments were super easy and the bases were very wide for great load distribution. I placed these on 1'x1'x2" pavers, which gave them room to move and settle as I proceeded with frame and subfloor joist construction. As I built the main frame to which these the piers were attached to, the increased weight compacted the ground underneath, and it was very easy to tweak the height adjustments on these piers. I would absolutely buy these again!

Put these under a small shed I needed leveled. They immediately crumpled, poor quality plastic, no strength at all.
