The Simpson EPB44-12 EPB Elevated Post Base for 4x4 with 12 in. Pipe is a cast-in-place post and column base from Simpson engineered to anchor 4x4 posts or columns securely to concrete. Designed for decks, patio covers, and other top-supported structures, this elevated base embeds into wet concrete via a 12 in. pipe anchor, creating a rigid connection while holding the post end above the slab to help prevent moisture-related rot.

Key Features

• Added standoff adjustability - accommodates a range of installation heights so the base suits a variety of project applications without requiring special modifications.
• Cast-in-place installation into wet concrete - the pipe anchor sets directly in fresh concrete, creating a strong, integrated connection that cures in place for lasting stability.
• Code-required 1 in. standoff with up to 2-1/2 in. adjustability - meets structural code minimums right out of the box while giving you the flexibility to raise the post higher above the concrete surface when drainage or clearance demands it.
• 12-gauge base plate construction with a 1-1/16 in. OD x 12 in. pipe - the heavy-gauge base plate and substantial pipe anchor provide a sturdy foundation for 4x4 post connections in demanding outdoor environments.
• Simpson Strong-Tie gray paint finish - the factory-applied coating provides a clean, consistent appearance while offering a layer of protection against the elements.
• Not recommended for non top-supported installations such as fences or unbraced carports - knowing the intended scope upfront helps you select the right connector for your specific structural conditions and avoid misapplication.

Why This Product

• Built-in rot prevention for long-term post integrity - the required 1 in. standoff keeps the bottom of the 4x4 post elevated above the concrete surface, reducing direct moisture contact and helping protect the post end over the life of the structure.
• Flexible standoff height for real-world conditions - the ability to adjust clearance up to 2-1/2 in. above concrete means this base can adapt to uneven slabs or applications where extra drainage clearance is a priority, without needing a different product.
• Straightforward wet-pour installation reduces extra steps - setting the base during the original concrete pour eliminates the need for post-cure anchoring hardware, streamlining the construction process for deck and patio cover projects.
• Made in the United States by a trusted structural connector brand - this base is produced domestically and carries the Simpson name, giving contractors and builders confidence in consistent quality and code-compliance for post base applications.
