The Simpson Elevated Post Base for 6x6 is a cast-in-place post and column base engineered to securely anchor 6x6 posts or columns to concrete - purpose-built for decks, patio covers, and other exterior structural applications where a reliable, code-compliant connection is critical. Simpson designed this base with a hot-dip galvanized finish and an adjustable elevated standoff that keeps post ends clear of moisture, making it a dependable choice for treated-wood construction and exposed outdoor environments.

Key Features

• Added standoff adjustability - suits a variety of project requirements, giving installers flexibility to dial in the right post height above the concrete surface
• Cast-in-place installation in wet concrete - the base is set during the pour for a secure, integrated connection that does not rely on post-pour anchoring
• Provides the code-required 1 in. standoff when properly installed; allows up to 2-1/2 in. of standoff above concrete (if desired) - keeps post ends elevated and protected from standing moisture, helping prevent rot and extending the life of the post
• Hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications - the heavy galvanized coating stands up to harsh outdoor conditions and the corrosive chemistry of pressure-treated lumber
• 12-gauge base plate with 1-1/16 in. OD x 8 in. pipe construction - delivers a sturdy, load-bearing assembly appropriate for structural deck and patio cover posts
• Not recommended for non top-supported installations (such as fences or unbraced carports) - knowing the correct application upfront helps buyers select the right connector and avoid costly installation errors

Why This Product

• Built-in rot protection at the post base - the elevated standoff design provides the code-required 1 in. clearance between the post end and the concrete, a critical detail for long-term structural integrity in outdoor post and beam applications
• Flexible standoff height for real-world conditions - adjustability up to 2-1/2 in. above the concrete surface means the base accommodates varying site conditions without requiring workarounds or custom hardware
• Hot-dip galvanized for demanding exterior use - the HDG finish provides extra corrosion resistance specifically suited to exterior environments and treated-wood contact, where standard coatings can break down prematurely
• American-made construction from Simpson - backed by Simpson engineering, this post base is manufactured to meet code requirements for deck and patio cover connections, giving contractors and homeowners confidence in both compliance and performance

Frequently Asked Questions

What is the standoff range this post base provides?

When properly installed, the EPB66HDG provides the code-required 1 in. standoff above the concrete surface and allows up to 2-1/2 in. of standoff if a greater clearance is desired for your application.

How is this post base installed?

The EPB66HDG is a cast-in-place base, meaning it is set into wet concrete during the pour. It should be installed with 0.162 in. x 3-1/2 in. nails to secure the post to the base plate.

Is this post base suitable for fences or unbraced carports?

No. The EPB66HDG is not recommended for non top-supported installations such as fences or unbraced carports. It is designed for applications where the top of the post is supported, such as decks and patio covers.

Why is hot-dip galvanization important for this post base?

Hot-dip galvanization (HDG) provides an extra layer of corrosion resistance, making the EPB66HDG well suited for exterior environments and applications involving treated wood, where standard coatings may not hold up over time.
