The Simpson Strong-Tie CB9-6 is a heavy-duty glulam column base engineered to deliver reliable post-to-concrete foundation connections for 9" x 6" glulam and engineered wood columns. Designed for cast-in-place or wet-set installation, this column base positions the bottom of the base plate flush with the concrete surface, providing full post bearing and maximizing load transfer. Built to handle demanding structural applications, the CB9-6 is the trusted choice for columns requiring high structural values and rugged, long-lasting performance in wind and seismic loading conditions.

Key Features

• Engineered to connect posts to concrete foundations across a wide range of lumber, glulam, and engineered wood product sizes
• Cast-in-place or wet-set installation with the base plate sitting flush with the concrete for full post bearing
• Increased uplift resistance for wind or seismic loading conditions
• Bolt hole locations meet code-required spacing for optimal load capacity
• Ideal for columns requiring high structural values and rugged performance
• Finished in Simpson Strong-Tie gray paint for durability and corrosion resistance
