Product Description
Simpson CBST44HDG CBST Hot-Dip Galvanized Standoff Column Base for 4x4 is a cast-in-place column base from Simpson Strong-Tie engineered to provide a secure and durable connection between wood posts and concrete foundations in residential and light commercial construction. Its code-required 1 in. standoff design elevates the post above the concrete surface to reduce moisture-related post-end rot, while hot-dip galvanization delivers superior corrosion resistance for demanding exterior and treated-wood applications.

Frequently Asked Questions
- Why does the CBST44HDG have a 1 in. standoff design?
- The code-required 1 in. standoff elevates the wood post above the concrete surface, preventing direct contact between the post end and moisture that can accumulate on concrete. This helps protect the post from moisture-related rot and extends the service life of the connection.
- What makes the hot-dip galvanized finish suitable for exterior applications?
- Hot-dip galvanization (HDG) applies a thick, metallurgically bonded zinc coating that provides extra corrosion resistance compared to standard finishes. This makes the CBST44HDG well suited for exterior environments and installations involving treated wood, where exposure to moisture and corrosive chemicals is a concern.
- What hardware is required to install the CBST44HDG?
- The CBST44HDG is installed with (2) 5/8 in. diameter machine bolts, which anchor the base to the concrete foundation as part of the cast-in-place installation process.
- What do the S-shaped bearing tabs on the CBST44HDG do?
- The S-shaped bearing tabs are engineered to provide increased strength in the connection, allowing for higher download capacity. This design enhancement improves the overall load-bearing performance and stability of the wood post-to-concrete connection.
