Frequently Asked Questions
- Why does the CBSTQ46Z-SDS2 feature a 1 in. standoff design?
- The 1 in. standoff elevates the wood post above the concrete surface, which is a code-required design feature that protects the post-end from direct contact with moisture, significantly reducing the risk of rot and extending the service life of the connection.
- What are the S-shaped bearing tabs and why do they matter?
- The S-shaped bearing tabs are structural elements built into the CBSTQ column base that provide increased strength, allowing the base to handle higher download loads compared to designs without them. This makes the CBSTQ a reliable choice for demanding residential and light commercial applications.
- Why are Strong-Drive SDS screws used instead of bolts?
- The included Strong-Drive SDS Heavy-Duty Connector screws provide a greater wood net section area than bolts. This means less material is removed from the wood member during fastening, preserving more of the post's structural integrity at the connection point.
- Is the CBSTQ46Z-SDS2 suitable for use with pressure-treated lumber?
- Yes. The ZMAX galvanization coating provides extra corrosion resistance specifically designed for exterior and treated-wood applications, making this column base well-suited for use with pressure-treated lumber where standard galvanization may not be sufficient.
