The Simpson ABU44Z 4×4 Adjustable Post Base is engineered for strength, durability, and ease of installation. Designed to anchor a nominal 4×4 wood post to concrete, it provides a strong connection while allowing for precise post placement during construction.
Made from 12-gauge steel and finished with Simpsons ZMAX coating, this base offers superior corrosion resistanceideal for outdoor applications where moisture is present. The base is slotted for adjustability, making it perfect for decks, patio covers, fences, and other wood-framed structures.
The unit includes a 1″ standoff to help prevent post-end rot by keeping the wood elevated above moisture-prone surfaces. Pre-drilled holes simplify installation with anchoring hardware (sold separately).
Installation Tip:
Secure the base to the concrete with a recommended anchor. Insert the post, align as needed, and fasten using approved Simpson Strong-Tie fasteners for a secure hold.
