The Simpson CB1010 Column Base by Simpson Strong-Tie is 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 into concrete, the base plate sits flush with the concrete surface to deliver full post bearing - providing a stable, code-compliant connection at the base of structural columns. Built from heavy 3-gauge steel and finished in Simpson Strong-Tie gray paint, this column base is the dependable choice for applications that demand high structural values and rugged, long-term performance.

Key Features

• Increased uplift resistance for wind or seismic loading - gives structural columns the holding power needed to perform in high-wind and seismic environments where uplift forces are a critical design concern.
• Bolt hole locations meet code-required spacing for optimal capacity - takes the guesswork out of installation by ensuring fastener placement is already positioned to achieve maximum allowable load values.
• Flush base plate design via cast-in-place or wet-set installation - positions the bottom of the base plate flush with the concrete surface so the full cross-section of the post bears directly on a solid foundation.
• Made from 3-gauge steel - the heavy steel construction delivers the rigidity and load capacity required for demanding post-to-foundation connections in structural applications.
• Simpson Strong-Tie gray paint finish - provides a consistent, recognizable finish that holds up through installation and suits both exposed and concealed structural column applications.

Why This Product

• Built for high-load structural columns - the combination of 3-gauge steel construction and code-compliant bolt hole spacing makes this post base well-suited for columns that carry significant loads, including lumber, glulam, and engineered wood members.
• Reliable in wind and seismic conditions - the increased uplift resistance designed into the CB1010 makes it a sound choice for projects in regions where wind uplift or seismic forces must be accounted for in the structural connection.
• Two installation methods give contractors flexibility - the option to cast in place or wet set the base into concrete means crews can adapt to job site conditions without compromising the integrity of the post-to-foundation connection.
• Sized specifically for 10x10 framing members - purpose-built for a nominal 10x10 column, this post base eliminates fit uncertainty and supports compatibility with the lumber, glulam, and engineered wood products most commonly used at that member size.

Frequently Asked Questions

What post size is the CB1010 designed for?

The CB1010 is designed for a nominal 10x10 column size and is compatible with lumber, glulam, and engineered wood products of that member size.

How is the CB1010 installed in concrete?

The CB1010 can be installed using either a cast-in-place or wet-set method. In both cases, the bottom of the base plate is positioned flush with the concrete surface to ensure full post bearing.

What fasteners are required to install the CB1010?

Installation requires (2) 3/4-in. diameter machine bolts. The bolt hole locations are designed to meet code-required spacing for optimal load capacity.

Is the CB1010 suitable for high-wind or seismic applications?

Yes. The CB1010 provides increased uplift resistance specifically designed for wind and seismic loading conditions, making it well-suited for structural applications where these forces are a concern.
