What Customers Are Saying
Customers overwhelmingly praise these deck supports for their ease of installation, lightweight design, and superior durability. Most highlight how simple setup is—simply level the ground and place blocks with no digging, tools, or expertise required. Many note they can carry stacks of 10 with ease, making solo projects manageable. Reviewers consistently confirm the blocks securely support 4x4 posts and beams for decks, sheds, and ground-level structures. Made from recycled plastic, they resist cracking and shifting under load. A few mention cost concerns, but most consider them an excellent investment for convenience and reliability.

Cost a little more but ya get so much more
Would RecommendThese post supports are great for what I needed. They’re much lighter than concrete supports, they provide a stable footing for the 4X4’s and yes they do cost more but what ya get far exceeds the cost incurred. For certain applications these supports are the way to go.
