The Simpson EPB44 Elevated Post Base for 4x4 by Simpson is a cast-in-place post base engineered to anchor the bottom of 4x4 posts or columns to concrete with a secure, code-compliant connection. Designed specifically for top-supported structures like decks and patio covers, it delivers the code-required 1 in. standoff between the post end and the concrete surface - helping to protect against moisture intrusion and reduce the risk of rot at the base of your post.

Key Features

• Cast-in-place installation into wet concrete - lets you set the base before the pour cures, creating a strong, integrated connection from the ground up rather than relying on surface anchors.
• Code-required 1 in. standoff with adjustability up to 2-1/2 in. above concrete - meets code minimums out of the box while giving you flexibility to increase clearance for drainage, ventilation, or site-specific conditions.
• Added standoff adjustability to suit a variety of applications - allows builders and contractors to adapt the post elevation to different project requirements without sourcing a different hardware model.
• 12-gauge base plate with 1-1/16 in. OD x 8 in. pipe construction - provides a robust structural foundation that supports consistent load transfer from the post to the concrete.
• Simpson Strong-Tie gray paint finish - delivers a clean, finished appearance and baseline corrosion resistance suited for exterior construction environments.
• Not recommended for non top-supported installations such as fences or unbraced carports - clearly defined application scope helps ensure the connector is used where it performs as engineered, keeping your project code-compliant and structurally sound.

Why This Product

• Built-in rot prevention by design - the code-required 1 in. standoff keeps the post end elevated above the concrete surface, reducing direct moisture contact and helping to extend the service life of wood posts in outdoor deck and patio cover applications.
• Flexible standoff height for real-world job site conditions - with adjustability from the required 1 in. minimum up to 2-1/2 in. above concrete, this post base accommodates a wider range of installation scenarios than a fixed-height base, reducing the need for custom solutions.
• Trusted Simpson construction hardware for top-supported structures - engineered specifically for decks and patio covers where posts carry vertical loads, giving contractors and builders confidence that the connector matches the structural demands of the application.
• Straightforward fastening compatibility - designed to install with 0.162 in. x 3-1/2 in. nails or #10 x 1-1/2 in. Strong-Drive SD screws, making it easy to complete the connection with fasteners commonly used on framing job sites.

Frequently Asked Questions

What is the required standoff height for the EPB44, and can it be adjusted?

When properly installed, the EPB44 provides the code-required 1 in. standoff above the concrete surface. It also offers standoff adjustability, allowing up to 2-1/2 in. of clearance above concrete if a greater elevation is desired for your application.

Is the EPB44 suitable for fences or unbraced carports?

No. The EPB44 is not recommended for non top-supported installations, such as fences or unbraced carports. It is designed for top-supported structures such as decks and patio covers.

How is the EPB44 installed, and what fasteners are required?

The EPB44 is a cast-in-place post base designed to be set into wet concrete. Once the post is positioned, it is fastened using 0.162 in. x 3-1/2 in. nails or #10 x 1-1/2 in. Strong-Drive SD screws.

What post size is the EPB44 compatible with?

The EPB44 is designed for a nominal 4x4 post size. It features a 12-gauge base plate and a 1-1/16 in. OD x 8 in. pipe to properly accommodate and secure a standard 4x4 post or column.
