Frequently Asked Questions
- Why does the CBST44Z have a 1 in. standoff design?
- The code-required 1 in. standoff elevates the wood post above the concrete surface, creating an air gap that protects the post end from direct moisture contact and significantly reduces the risk of post-end rot over time.
- What is ZMAX galvanization and why does it matter?
- ZMAX is a thicker zinc coating applied to the steel that provides extra corrosion resistance compared to standard galvanization. This makes the CBST44Z especially well suited for exterior applications and use with treated lumber, where exposure to moisture and corrosive preservatives is a concern.
- What hardware is required to install the CBST44Z?
- Install with (2) 5/8 in. diameter machine bolts. These bolts anchor the base into the concrete during the cast-in-place installation process.
- What do the S-shaped bearing tabs do?
- The S-shaped bearing tabs are a structural feature that provides increased strength to the connection, allowing the CBST44Z to handle higher download loads compared to simpler flat-tab designs, making it suitable for demanding residential and light commercial construction applications.
