The Simpson EPB44MB Elevated Post Base for 4x4 Posts is a cast-in-place post and column base engineered by Simpson Strong-Tie to create a secure, code-compliant connection between 4x4 posts or columns and concrete footings. Designed for decks, patio covers, pergolas, and other top-supported structural applications, this elevated post base embeds directly into wet concrete and delivers the adjustable standoff clearance needed to protect post ends from moisture-related rot - making it a dependable foundation solution for outdoor structural builds.

Key Features

• Cast-in-place installation into wet concrete - sets the base permanently during the pour, eliminating the need for anchor bolts or drilling into hardened concrete and simplifying the footing process.
• Adjustable standoff range from the code-required 1 in. up to 2 1/2 in. above the concrete surface - gives contractors and builders flexibility to suit varying site conditions and application requirements while maintaining code compliance.
• Code-required 1 in. standoff when properly installed - keeps the post end elevated above the concrete surface to reduce moisture contact and help prevent rot, meeting structural code requirements for post-to-concrete connections.
• 12-gauge base plate construction with a 1-1/16 in. OD x 8 in. pipe - provides a sturdy, well-proportioned base that delivers reliable load transfer from the post down into the concrete footing.
• Simpson Strong-Tie gray paint finish - offers a clean, consistent appearance suitable for exposed outdoor structural applications where finish quality matters.
• Installs with 0.162 in. x 3-1/2 in. nails or #10 x 1-1/2 in. Strong-Drive SD screws - compatible with common fastener options so crews can use familiar hardware without sourcing specialty fasteners.
• Nominal post size 4x4 - engineered specifically for standard 4x4 framing lumber, ensuring a properly fitted, structurally sound connection without field modification.
• Not recommended for non top-supported installations such as fences or unbraced carports - clearly defined application limits help specifiers and builders select the right base for the job and avoid improper use.
• Packaged as a 50-count carton - supplies enough bases for a full deck or patio cover project in a single order, reducing reorder interruptions on larger jobs.

Why This Product

• Built-in rot protection through adjustable standoff - by holding the post end between 1 in. and 2 1/2 in. above the concrete surface, this base actively reduces the moisture exposure that leads to post deterioration over time, extending the service life of the entire structure.
• Engineered specifically for top-supported applications like decks and patio covers - rather than a general-purpose connector, this base is purpose-matched to the structural conditions where it performs best, giving builders confidence in long-term performance under real-world loading.
• Streamlined wet-concrete installation - embedding directly into the footing pour means no return trips to drill, anchor, or epoxy into cured concrete, keeping project timelines tighter and labor costs lower.
• Trusted Simpson Strong-Tie engineering and finish - the gray paint finish and domestic manufacturing back a connector built to the quality standards that structural contractors rely on for code-inspected, load-bearing connections.

Frequently Asked Questions

What is the standoff range provided by the EPB44MB?

When properly installed, the EPB44MB provides the code-required 1 in. standoff above concrete. The design also allows up to 2-1/2 in. of standoff above the concrete surface if a greater clearance is desired for a specific application.

Can the EPB44MB be installed into hardened concrete?

No. The EPB44MB is a cast-in-place post base designed specifically for installation into wet concrete. It is not intended for attachment to existing hardened concrete.

Is the EPB44MB suitable for fence posts or unbraced carports?

No. The EPB44MB is not recommended for non top-supported installations such as fences or unbraced carports. It is designed for top-supported structural applications such as decks and patio covers.

What fasteners are required to secure the post to the EPB44MB?

The post is secured to the base using 0.162 in. x 3-1/2 in. nails or #10 x 1-1/2 in. Strong-Drive SD screws.
