The Simpson ABU44Z 4x4 Adjustable Post Base is engineered for strength, durability, and ease of installation. Designed to anchor a nominal 4x4 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 Simpson’s ZMAX coating, this base offers superior corrosion resistance—ideal 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).

Features:

• ZMAX Finish: Provides heavy-duty corrosion resistance for outdoor and pressure-treated lumber use.
• 1" Elevated Standoff: Helps reduce moisture contact, preventing rot at the base.
• Slotted Base: Allows for precise post placement and alignment.
• 12-Gauge Steel Construction: Ensures long-lasting structural strength.
• Versatile Applications: Commonly used in decks, fences, and porch framing.
• Easy Installation: Compatible with standard 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.
