The Simpson CB44 Galvanized Column Base for 4x4 by Simpson is engineered to connect posts to concrete foundations across a wide range of lumber, glulam, and engineered wood product sizes. Designed for either cast-in-place or wet-set installation, the base plate sits flush with the concrete surface to ensure full post bearing for maximum load transfer. Built from 7-gauge steel with a G90 galvanized zinc coating, this column base is the dependable choice for structural applications where high load capacity and long-term durability are non-negotiable.

Key Features

• Increased uplift resistance for wind or seismic loading - helps keep the post-to-concrete connection secure in high-stress environments where lateral and uplift forces are a concern
• Bolt hole locations meet code-required spacing for optimal capacity - simplifies the installation process while ensuring the connection performs to its rated structural values
• Nominal column size: 4x4 - sized to fit standard 4x4 lumber, glulam, and engineered wood products for a reliable, tight fit without field modification
• Made from 7-gauge steel - provides the heavy-duty strength needed for columns requiring high structural values and rugged performance
• Galvanized (G90) for extra corrosion resistance - the zinc coating guards against moisture-related deterioration, extending the service life of the connector in demanding conditions

Why This Product

• Cast-in-place or wet-set versatility - the CB44 supports two concrete installation methods, giving contractors and builders the flexibility to match their preferred workflow without sacrificing structural integrity
• Built for structural-grade performance - 7-gauge steel construction combined with code-compliant bolt hole spacing makes this post base well-suited for columns that carry significant loads, including those in wind- or seismic-prone regions
• G90 galvanized coating for long-term reliability - the zinc galvanized finish provides a meaningful layer of corrosion protection, making this column base a smart choice for exterior or moisture-exposed applications where an uncoated connector would degrade over time
• Made in the United States by Simpson - backed by a brand with a strong reputation in structural connectors and hardware, offering builders confidence in consistent quality and engineering standards

Frequently Asked Questions

What installation methods are available for the CB44 column base?

The CB44 is designed for either cast-in-place or wet-set installation into concrete. In both methods, the bottom of the base plate sits flush with the concrete surface, ensuring full post bearing for maximum load transfer.

What type of posts or beams is the CB44 compatible with?

The CB44 is compatible with a wide range of lumber, glulam, and engineered wood products sized at a nominal 4x4. It is well-suited for applications requiring high structural values.

What fasteners are required to install the CB44?

Installation of the CB44 requires two 5/8-in. diameter machine bolts. The bolt hole locations are positioned to meet code-required spacing for optimal load capacity.

How does the G90 galvanized coating benefit the CB44?

The G90 galvanized zinc coating provides extra corrosion resistance, making the CB44 suitable for environments where moisture exposure could compromise the long-term integrity of an uncoated steel connector.
