The Simpson EPB44A Galvanized Elevated Post Base is a cast-in-place post base engineered by Simpson to anchor 4x4 posts and columns securely to concrete in top-supported structural applications. Built for decks, patio covers, and similar outdoor construction, it delivers the code-required 1 in. standoff above the concrete surface to keep post ends clear of moisture and help prevent rot - making it a reliable foundation component wherever long-term structural integrity matters.

Key Features

• Adjustable standoff height (1 in. to 2 in. above concrete) - meets the code-required 1 in. minimum while offering flexibility up to 2 in. of clearance, so the base suits a wider range of project conditions without special modification
• Cast-in-place design for wet concrete installation - sets directly into the concrete during the pour for a stronger, more integrated connection than surface-mounted alternatives
• 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, supporting long-term structural performance
• 14-gauge steel construction - provides solid, dependable strength appropriate for load-bearing post and column base applications
• G90 zinc galvanized coating - adds a robust layer of corrosion resistance well-suited to outdoor environments such as deck footings and patio cover anchoring
• Sized for nominal 4x4 posts - fits standard framing lumber directly, keeping installation straightforward without custom fitting or shimming
• Not recommended for non top-supported installations - clearly defined application scope (fences and unbraced carports are excluded) ensures the base is used in conditions where it performs as designed and tested

Why This Product

• Built-in rot protection through elevated standoff - the 1 in. code-required clearance lifts post ends away from concrete where moisture tends to collect, directly addressing one of the most common causes of premature post failure on decks and patio covers
• Flexible standoff adjustment for real-world conditions - the ability to set standoff height anywhere from 1 in. up to 2 in. above concrete gives builders practical latitude to accommodate slight variations in pour height or finished surface level without compromising compliance
• Permanent, integrated concrete connection - because the EPB44A installs directly into wet concrete, the anchor becomes part of the footing itself rather than sitting on top of a cured surface, resulting in a more secure and structurally sound post-to-foundation connection
• Corrosion-resistant finish for outdoor longevity - the G90 zinc galvanized coating is specifically suited to the exposed, moisture-prone conditions common in deck and patio construction, helping the base maintain its structural integrity over time without premature degradation

Frequently Asked Questions

How much standoff clearance does the EPB44A provide above the concrete surface?

When properly installed, the EPB44A provides the code-required 1 in. standoff above the concrete surface. It also allows up to 2 in. of standoff above concrete if desired, offering added adjustability for a variety of applications.

Is the EPB44A suitable for installation in wet concrete?

Yes. The EPB44A is specifically designed as a cast-in-place post base, making it fully suitable for installation in wet concrete during the pour.

Can the EPB44A be used for fences or unbraced carports?

No. The EPB44A is not recommended for non top-supported installations such as fences or unbraced carports. It is intended for use in top-supported structural applications such as decks and patio covers.

What corrosion protection does the EPB44A offer?

The EPB44A is made from 14-gauge steel with a G90 zinc galvanized coating, providing extra corrosion resistance suitable for outdoor applications like decks and patio covers.
