The Simpson Strong-Tie CB6-7 is a 6" column base engineered to provide a secure, high-strength connection between posts and concrete foundations. Designed for use with a wide range of lumber, glulam, and engineered wood product sizes, this column base is cast-in-place or wet-set directly into concrete so the bottom of the base plate sits flush with the surface, ensuring full post bearing. Built to deliver high structural values and rugged performance, the CB6-7 is an excellent choice for columns subject to demanding load conditions including wind and seismic forces.

Frequently Asked Questions

What column size is the CB6-7 designed to fit?

The CB6-7 is designed for use with 6X column sizes, making it compatible with lumber, glulam, and engineered wood products in that dimension range.

How is the CB6-7 installed?

The CB6-7 is installed using a cast-in-place or wet-set method, meaning the base is set directly into concrete while it is still wet. This allows the base plate to sit flush with the concrete surface, ensuring full post bearing once the concrete cures.

What fasteners are required to secure the post to the CB6-7?

The CB6-7 requires two 5/8" bolts to connect the post to the column base. The bolt hole locations are positioned to meet code-required spacing for optimal load capacity.

Is the CB6-7 suitable for applications with wind or seismic loads?

Yes, the CB6-7 is engineered with increased uplift resistance, making it well suited for structural column applications subject to wind or seismic forces. It is designed to deliver high structural values under demanding load conditions in both residential and commercial construction.
