The Simpson 6 x 8 Column Base Hot Dip Galvanized is a heavy-duty structural connector from Simpson engineered to anchor 6 x 8 posts and columns securely to concrete foundations and footings. Compatible with lumber, glulam, and engineered wood products, this hot-dip galvanized base is built for demanding structural applications - from residential decks and pergolas to commercial framing projects where reliable, long-term column connections are non-negotiable.

Key Features

• Hot-dip galvanized finish - provides robust corrosion resistance for outdoor, exposed, and high-moisture environments where untreated hardware would fail prematurely
• Designed for 6 x 8 lumber, glulam, and engineered wood products - gives contractors and builders flexibility to use the connector across a broad range of column materials without needing a different base
• Cast-in-place or wet-set installation - allows the base plate to sit flush with the concrete surface, delivering full post bearing and efficient load transfer to the foundation
• Enhanced uplift resistance - makes this connector well-suited for structures subject to wind or seismic forces, supporting compliance with code requirements in demanding conditions
• Accepts two 5/8 in. bolts - bolt hole locations are designed to meet code-required standards, ensuring a properly engineered connection every time
• Made in the United States - confirms consistent manufacturing quality backed by Simpson's engineering standards

Why This Product

• Built for tough environments - the hot-dip galvanized coating goes beyond standard finishes, making this column base a dependable choice for exposed outdoor structures, coastal projects, and any installation where long-term corrosion resistance matters
• Versatile column compatibility - supporting lumber, glulam, and engineered wood products in the 6 x 8 dimension, this base fits a wide variety of structural column types, reducing the need for project-specific hardware sourcing
• Engineered for high-load and code-sensitive applications - whether connecting columns on a covered carport, a pergola, or a commercial framing project subject to wind uplift or seismic loading, this connector is designed to meet the structural demands of the job
• Trusted Simpson engineering - backed by one of the most recognized names in structural connectors, this column base delivers the design confidence and installation reliability that builders and engineers count on for load-critical connections

Frequently Asked Questions

What column size is the CB68HDG designed to fit?

The CB68HDG is designed for 6 x 8 posts and columns, and is compatible with lumber, glulam, and engineered wood product sizes in that dimension.

What fasteners are required to install the CB68HDG?

Installation requires two 5/8" bolts. Bolt hole locations on the CB68HDG are designed to meet code-required spacing for optimal load capacity.

How is the CB68HDG installed?

The CB68HDG is designed for cast-in-place or wet-set installation into concrete. The base plate sits flush with the concrete surface to provide full post bearing and efficient load transfer between the post and the foundation.

Why is the CB68HDG finished with hot-dip galvanizing rather than a standard coating?

Hot-dip galvanizing provides superior corrosion resistance compared to standard coatings, making the CB68HDG well suited for exposed or harsh environments where moisture, weather, or other corrosive conditions are a concern. This finish supports long-term performance in demanding applications such as outdoor decks, pergolas, carports, and covered structures.
