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.

I needed to install another post on the concrete pad to attach the other side of the trellis to, so I chose this to complete the job.
