The Simpson CB1212 Column Base is engineered to connect posts to concrete foundations, accommodating a wide range of lumber, glulam, and engineered wood product sizes. This heavy-duty column base is either cast-in-place or wet set into concrete, with the bottom of the base plate sitting flush with the concrete surface to ensure full post bearing. Built from 3-gauge steel and finished in Simpson Strong-Tie gray paint, the CB1212 delivers the high structural values and rugged performance demanded by large-scale column applications requiring a nominal 12x12 member size.

Frequently Asked Questions

What column size is the CB1212 designed for?

The CB1212 is designed for a nominal 12x12 member size and is compatible with lumber, glulam, and engineered wood product columns of that dimension.

How is the CB1212 installed into concrete?

The CB1212 can be either cast-in-place or wet set into concrete. In both methods, the bottom of the base plate sits flush with the concrete surface to ensure full post bearing. The column base is secured using two 3/4-in. diameter machine bolts, which are not included.

What material and finish is the CB1212 made from?

The CB1212 is made from 3-gauge steel and is finished in Simpson Strong-Tie gray paint, providing a durable coating suited for heavy-duty structural applications.

Is the CB1212 suitable for use in wind or seismic conditions?

Yes. The CB1212 features increased uplift resistance for wind or seismic loading, and its bolt hole locations meet code-required spacing for optimal load capacity, making it well suited for structural column applications subject to these forces.
