The Simpson 8 X 10 Column Base Powder Coated is a cast-in-place post and column base engineered by Simpson to prevent wood members from rotating at their base. Designed so the bottom of the base plate sits flush with the concrete surface, this column base delivers a clean, low-profile appearance alongside structural reliability for top-supported column and post installations - including those subject to wind or earthquake loading.

Key Features

• Cast-in-place design with flush base plate - the bottom of the base plate sits level with the concrete surface, resulting in a finished, professional look with no raised lip or exposed hardware gap
• Rotation resistance at the base - prevents wood members from rotating about the base, adding critical stability to supported column installations where lateral movement cannot be tolerated
• Textured flat black powder-coat finish - far more durable and visually refined than standard paint, holding up to the elements while contributing a consistent, finished aesthetic on exposed column bases
• 3 gauge heavy-duty steel construction - thick-gauge steel provides long-term structural performance and resists deformation under load in demanding installations
• Wind and earthquake load applicability - approved for applications subject to wind or earthquake loading where a 60% load increase factor applies, expanding the range of structural projects this base can serve

Why This Product

• American-made quality from a trusted structural hardware brand - built in the United States by Simpson, this column base reflects the manufacturing standards and engineering accountability that structural professionals rely on
• Flush installation means no compromises on appearance - the base plate's flush-with-concrete positioning suits both functional framing and finish-sensitive projects where exposed hardware must look intentional and clean
• Purpose-engineered for rotation resistance - unlike generic post hardware, this base is specifically designed to prevent member rotation, making it the right choice for top-supported columns where stability at the base directly affects the integrity of the structure above
• Powder-coat durability over painted alternatives - the textured black powder-coat finish offers a more resilient surface than conventional paint, reducing the likelihood of chipping, fading, or corrosion over time in exposed outdoor or semi-exposed applications

Frequently Asked Questions

How is the CB810PC column base installed?

The CB810PC is a cast-in-place column base. It is installed with the bottom of the base plate flush with the concrete surface. All specified fasteners must be used, including (2) 5/8" bolts, to achieve rated performance.

Can the CB810PC be used for fence posts or other non-top-supported installations?

No. Post bases like the CB810PC do not provide adequate resistance to prevent members from rotating about the base, and therefore are not recommended for non-top-supported installations such as fences.

What finish does the CB810PC feature, and why is it beneficial?

The CB810PC features a Textured Black Powder-Coat finish. This finish produces a much more durable and better-looking result than standard paint, making it well suited for exposed or decorative structural applications.

Are the load values on the CB810PC adjusted for wind or seismic conditions?

Yes. Allowable loads for the CB810PC have been increased 60% for wind or earthquake loading. No further increase is allowed, and loads should be reduced where other governing load conditions apply.
