What Customers Are Saying

Customers overwhelmingly praise these post anchors for their heavy-duty construction, rock-solid stability, and ability to prevent rot by elevating posts off concrete. The ZMAX coating resists corrosion effectively, and the pre-drilled holes with split-side design allow easy alignment during installation. Most reviewers highlight durability and code compliance as key strengths, calling them the best choice for decks and outdoor structures. A few mention needing additional washers or note alignment requires patience, but these minor concerns barely diminish the strong consensus that performance justifies the investment for critical structural applications.

Quality Strong-Tie Base

Would Recommend

We used the Simpson Strong-Tie ABA 4-in x 4-in ZMAX Wood to concrete (retrofit) Base for our deck project and these worked great. They gave us confidence that it will hold up well against moisture and ground contact. Highly recommend these for any deck or outdoor build where you want strength and long-lasting durability!

Great for support posts

Would Recommend

These are great for the bottom of posts. They keep the post about an inch off the ground and they’re sturdy. I wish I could use these for fence posts as well.
