The Simpson Strong-Tie CB68PC Column Base is a cast-in-place post base engineered to anchor 6 x 8 wood column members securely to concrete foundations. Designed with its base plate flush to the concrete surface, this column base delivers a clean, low-profile installation while effectively preventing wood members from rotating at the base. The CB68PC is finished in a textured flat black powder coat - a significantly more durable and visually refined finish than standard paint - making it equally at home in structural and architectural applications where appearance matters.

Note: Fasteners are not included. (2) 5/8" bolts are required for installation.
Installation Guidelines
- Use all specified fasteners as outlined in the installation requirements
- Allowable loads have been increased 60% for wind or earthquake loading; no further increase is allowed - reduce where other loads govern
- Minimum side cover for full loads is 3" for CB-series bases
- Install all models with the bottom of the base plate flush with the concrete surface
- Post bases do not provide adequate resistance to prevent members from rotating about the base and are therefore not recommended for non-top-supported installations such as fences

Note: Product dimensions and/or screw or bolt holes may differ from picture.
Frequently Asked Questions
- What size wood column is the CB68PC designed to fit?
- The CB68PC is specifically engineered to anchor 6 x 8 wood column members. It is not intended for use with other column dimensions, so confirming your column size before purchasing is important.
- How does the CB68PC attach to the concrete foundation?
- The CB68PC is a cast-in-place column base, meaning the base plate is installed flush with the concrete surface during the pour. It is secured using two 5/8" bolts, resulting in a clean, low-profile connection between the wood column and the concrete foundation.
- Is the CB68PC suitable for use with pressure-treated lumber?
- No, the CB68PC is not approved for use with treated lumber. If your application involves pressure-treated wood columns, a different Simpson Strong-Tie column base rated for treated lumber should be selected.
- What makes the black powder-coat finish on the CB68PC different from standard paint?
- The CB68PC features a textured flat black powder-coat finish, which is described as more durable and better-looking than standard paint. This makes the connector well suited for both structural applications and architectural settings where the appearance of exposed hardware is important.
