Product Description

The Simpson CB44SS Stainless-Steel Column Base is engineered to securely connect posts to concrete foundations, accommodating a wide range of lumber, glulam, and engineered wood product sizes. This 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 provide full post bearing. Built from heavy-duty 7-gauge stainless steel, the CB44SS delivers exceptional structural performance and is ideal for columns that demand high load values and rugged, long-term reliability - especially in high or severe corrosion environments where standard steel hardware would fail.

Why is stainless steel important for this column base?
The stainless steel material and finish provide high and severe corrosion resistance, making the CB44SS suitable for environments where standard steel hardware would be prone to corrosion failure, such as coastal or chemically exposed locations.
How is the CB44SS installed in concrete?
The CB44SS is either cast-in-place or wet set into concrete so that the bottom of the base plate sits flush with the concrete surface, providing full post bearing. Installation requires two 5/8-in. diameter stainless-steel machine bolts.
Is the CB44SS suitable for high-load structural applications?
Yes. The CB44SS is built from heavy-duty 7-gauge stainless steel and features increased uplift resistance for wind or seismic loading. Its bolt hole locations also meet code-required spacing for optimal load capacity, making it ideal for columns that require high structural values and rugged performance.
