The Simpson Strong-Tie CB9-10.5 is a heavy-duty glulam column base engineered to deliver a secure, code-compliant connection between posts and concrete foundations. Designed specifically for a 9" x 10.5" glulam column size, this column base is cast-in-place or wet-set into concrete so that the bottom of the base plate sits flush with the surface, enabling full post bearing and maximum load transfer. Finished in Simpson Strong-Tie gray paint and manufactured in the United States, the CB9-10.5 is built to meet the demands of high-load structural applications where dependable uplift resistance and rugged performance are essential.

Key Features

• Full Post Bearing: Base plate sits flush with the concrete surface for complete, uniform post bearing and efficient load distribution.
• Increased Uplift Resistance: Engineered to provide enhanced resistance against wind and seismic loading forces.
• Code-Required Bolt Hole Spacing: Bolt hole locations are positioned to meet code-required spacing for optimal structural capacity.
• Versatile Installation: Suitable for cast-in-place or wet-set concrete installation methods.
• High Structural Values: Ideal for columns requiring demanding load ratings and rugged, long-term performance.
• Durable Finish: Coated in Simpson Strong-Tie gray paint for corrosion resistance and lasting durability.

Frequently Asked Questions

What column size is the CB9-10.5 designed to fit?

The CB9-10.5 is designed specifically for a glulam column measuring 9" x 10.5". It is not intended for standard dimensional lumber posts, as it is engineered to match the exact dimensions of a glulam column of that size.

How is the CB9-10.5 installed into concrete?

The CB9-10.5 is designed for either cast-in-place or wet-set concrete installation. In both methods, the base plate is set flush with the concrete surface, which allows for full post bearing and maximum load transfer from the column to the foundation.

What fasteners are required to install the CB9-10.5?

Installation of the CB9-10.5 requires bolts - specifically two bolts. The bolt hole locations on the base are positioned to meet code-required spacing for optimal structural capacity.

What finish does the CB9-10.5 have, and does it offer corrosion resistance?

The CB9-10.5 is coated in Simpson Strong-Tie gray paint, which provides corrosion resistance and lasting durability for long-term performance in demanding structural applications.
