The Simpson Elevated Post Base for 4x6 is a cast-in-place anchor engineered to create a secure, code-compliant connection between a 4x6 post and a concrete footing. Built for decks, patio covers, and similar top-supported exterior structures, this post base features a hot-dip galvanized finish that delivers enhanced corrosion resistance in outdoor and treated-lumber applications. The cast-in-place design installs directly in wet concrete, and the adjustable standoff height keeps the post end clear of moisture contact - helping protect the structural integrity of the connection over time.

Key Features

• Adjustable standoff height - provides the code-required 1 in. clearance above concrete when properly installed, and allows up to 2-1/2 in. of standoff if greater clearance is needed, giving you flexibility across a variety of project conditions.
• Cast-in-place installation in wet concrete - sets directly into fresh concrete before it cures, creating a permanent, solid anchor without the need for drilling into hardened concrete after the fact.
• Hot-dip galvanized finish - offers extra corrosion resistance compared to standard coatings, making this base well suited for exterior post-to-concrete connections and applications involving treated wood.
• 12-gauge base plate with 1-1/16 in. OD x 8 in. pipe - the heavy-gauge construction provides a rigid, stable foundation for the post, supporting the structural demands of decks and patio covers.
• Designed for top-supported applications only - intended for structures like decks and patio covers where the post is supported from above; not recommended for fences or unbraced carports, so you can be confident this base is matched to the right job type.

Why This Product

• Built-in moisture protection - the elevated standoff keeps the post end raised above the concrete surface, reducing direct moisture exposure at the base of the post and helping extend the life of the structural connection.
• Corrosion-resistant finish for demanding environments - hot-dip galvanization provides a higher level of protection than standard finishes, making this post base a dependable choice for exterior decks, patio covers, and installations where treated lumber is used.
• Flexible standoff range suits multiple applications - the ability to dial in anywhere from the code-required 1 in. up to 2-1/2 in. of standoff height means this single base can adapt to varying site conditions without requiring a different product.
• Straightforward wet-concrete installation - setting the base during the pour eliminates extra steps and hardware, making it a practical choice for new construction footings and concrete piers.

Frequently Asked Questions

What standoff height does the EPB46HDG provide above the concrete surface?

When properly installed, this post base provides the code-required 1 in. standoff above the concrete. It also allows up to 2-1/2 in. of standoff above concrete if a greater clearance is desired for your application.

Can the EPB46HDG be installed in wet concrete?

Yes. The EPB46HDG is a cast-in-place post base designed specifically to be installed in wet concrete, creating a secure and permanent connection once the concrete cures.

Is the EPB46HDG suitable for use with treated lumber?

Yes. The hot-dip galvanized (HDG) finish provides extra corrosion resistance, making this post base well suited for exterior applications and use with treated wood.

Are there any installations for which the EPB46HDG is not recommended?

This post base is not recommended for non top-supported installations, such as fences or unbraced carports. It is intended for top-supported structural applications like decks and patio covers.
