The Simpson Glulam Column Base CB7-6 6.75 x 6 Inch from Simpson is a heavy-duty column base engineered to deliver a secure, high-capacity connection between glulam posts and concrete foundations. Designed specifically for a 6.75 in. x 6 in. glulam column, this base uses a cast-in-place or wet-set installation method so the base plate sits flush with the concrete surface, ensuring full post bearing and long-term structural reliability. Built for demanding residential and commercial applications, it is a go-to solution wherever strong column-to-foundation connections and resistance to wind or seismic forces are required.

Key Features

• Cast-in-place or wet-set installation - the base plate sits flush with the concrete surface, providing full post bearing and a clean, stable foundation connection without raised hardware that could compromise bearing area.
• Engineered for 6.75 in. x 6 in. glulam columns - precise sizing eliminates guesswork and ensures a proper fit with glulam, lumber, and engineered wood products, reducing installation errors on structural projects.
• High uplift resistance - designed to handle wind and seismic loading demands, giving builders confidence that column connections will perform in code-required structural applications.
• Bolt hole locations meet code-required spacing - optimized fastener placement supports maximum load capacity and simplifies the inspection and approval process on permitted projects.
• Simpson gray paint finish - provides a consistent, corrosion-resistant surface appropriate for the structural environments where this column base is typically installed.
• American-made construction - produced to the quality standards expected from a trusted name in structural connectors, supporting confidence in material consistency and performance.

Why This Product

• Purpose-built fit for glulam construction - with dimensions matched specifically to a 6.75 in. x 6 in. glulam column, this base integrates cleanly into engineered wood framing systems, saving time and avoiding compatibility issues common with generic hardware.
• Wind and seismic load capacity built in - the increased uplift resistance makes this column base a dependable choice for projects in high-load zones where structural connectors are subject to strict engineering and code requirements.
• Flush installation for full post bearing - the cast-in-place or wet-set method means no gap between post and base, maximizing the bearing surface and contributing to the overall integrity of the structural column connection.
• Versatile across structural applications - suitable for both residential and commercial column base connections involving lumber, glulam, and engineered wood products, making it a practical single-solution choice across a range of project types.

Frequently Asked Questions

What column size is the CB7-6 designed to fit?

The CB7-6 is designed specifically for a 6.75" x 6" glulam column. It is also compatible with a wide range of lumber, glulam, and engineered wood product sizes.

How is the CB7-6 installed - does it sit above or flush with the concrete?

The CB7-6 is designed for cast-in-place or wet-set installation, meaning the base plate sits flush with the concrete surface. This method provides full post bearing and exceptional structural integrity.

What fasteners are required to install the CB7-6?

The CB7-6 requires two 5/8" bolts. The bolt hole locations are also designed to meet code-required spacing for optimal load capacity.

What types of structural applications is the CB7-6 suited for?

The CB7-6 is suited for connecting glulam posts and columns to concrete foundations, structural applications requiring high uplift resistance due to wind or seismic loading, and cast-in-place or wet-set concrete foundation installations where high structural values and rugged, long-term performance are required.
