Ratings may include incentivized customer reviews.
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.

Would RecommendI used this on a flip to replace old worn out wood that wasn't attached to the deck. Easy to use with a good design

Post will lean
Would Not RecommendDo not attach a fence to posts anchored with these anchors. They will lean in no time!
So far so good
Would RecommendI got these to build a pergola, and then tie that into a fence, around my existing in-ground pool deck. These are holding strong. They need a 1/2" anchor bolt, but also have 2 holes for smaller screw-type anchors for extra security. They attach to the 4x4 with 3 screws on each side. The result seems quite solid. I'll update this review when I finish the build.

Hi Rnor, this is Colin from Simpson Strong-Tie. A fence post will lean when placed in the ABA44Z. This is called rotation about the base of the post....
