Product Description
Simpson CBSQ88-SDS2HDG CBSQ Hot-Dip Galvanized Standoff Column Base for 8x8 with SDS Screws by Simpson Strong-Tie is an engineered standoff column base designed to create a secure, code-compliant connection between an 8x8 post or column and a concrete footing. Ideal for decks, patio covers, and other top-supported structures, this base provides a 1 in. standoff that keeps post and column ends elevated above concrete - reducing the potential for decay - while its hot-dip galvanized finish delivers superior corrosion resistance for exterior and treated-wood applications.

Frequently Asked Questions
- How is the CBSQ88-SDS2HDG installed - in wet or hardened concrete?
- This column base embeds in wet concrete at the time of pour. Install the CBSQ with the bottom of the standoff flush to the top of the concrete surface to ensure proper placement and code compliance.
- Why does this column base have a 1 in. standoff?
- The 1 in. standoff between the post and the concrete surface meets code requirements and reduces the potential for decay at post and column ends by preventing direct contact between the wood and the concrete.
- What fasteners are used to install the CBSQ88-SDS2HDG, and are they included?
- The base installs with 1/4 in. x 2 in. Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product. These screws allow for fast installation, a reduced reveal, and high load capacity.
- Why is the hot-dip galvanized finish important for this column base?
- Hot-dip galvanization (HDG) provides extra corrosion resistance, making this column base well-suited for exterior applications and use with treated lumber, where standard coatings may be insufficient over time.
