The Simpson CBS44 CBS Galvanized Standoff Column Base for 4x4 by Simpson is a structural connector engineered to anchor 4x4 posts and columns directly into wet concrete at the time of pour, creating a reliable load path that transfers structural stresses from the column down to the footing. The built-in 1 in. standoff clearance keeps the base of the post elevated above the concrete surface, protecting column ends from moisture contact and helping meet code requirements for exposed structural applications. Trusted by engineers and contractors on residential and commercial projects alike, this galvanized column base combines precise engineering, rigorous testing, and high manufacturing standards to deliver consistent, dependable performance.

Key Features

• Shipped with base plate assembled - arrives ready to install, saving setup time and reducing the chance of misalignment during the concrete pour.
• 1 in. standoff clearance required by code - the elevated base plate keeps the post end off the concrete surface, satisfying code requirements and reducing moisture exposure at the column base.
• Standoff design reduces potential for decay at post and column ends - by preventing direct contact between wood and concrete, this post base helps extend the service life of structural columns in weather-exposed conditions.
• Designed for nominal 4x4 column size - engineered to fit standard 4x4 structural posts, making it a straightforward choice for decks, pergolas, carports, and similar framing applications.
• Dual-gauge steel construction (base 12, strap 10) - heavier strap gauge where load transfer demands are greatest provides strength where it counts without unnecessary bulk throughout the assembly.
• Zinc Galvanized G90 coating - provides extra corrosion resistance, making this column base well-suited for outdoor, wet, or high-humidity environments where bare steel would deteriorate quickly.

Why This Product

• Code-compliant standoff built in - the 1 in. clearance is not an add-on or an afterthought; it is a core design feature of the CBS44, so builders can satisfy code requirements for post-base standoff without sourcing additional hardware or modifying the installation.
• Embeds at pour for a permanent, integrated connection - setting the base directly in wet concrete creates a fixed anchor point that becomes part of the foundation itself, eliminating the need for post-cure drilling or anchor bolt retrofitting.
• G90 galvanized coating for long-term durability outdoors - the corrosion-resistant finish makes this standoff column base a practical choice for exterior structures such as decks, fences, patio covers, and agricultural buildings where moisture exposure is a recurring concern.
• Engineered and tested by Simpson - Simpson connectors are designed to perform under documented load conditions and manufactured to consistent quality standards, giving builders and engineers confidence that the connector will perform as intended across a wide range of structural applications.

Frequently Asked Questions

How is the CBS44 installed?

The CBS44 column base is designed to embed directly in wet concrete at the time of pour. Once the concrete has cured, the column is secured using 5/8 in. diameter machine bolts.

Why does the CBS44 have a 1 in. standoff?

The 1 in. standoff clearance is required by code for structural posts that may be exposed to weather or water splash. This gap between the base of the column and the concrete surface significantly reduces the potential for moisture-related decay at post and column ends.

What size post or column is the CBS44 designed for?

The CBS44 is designed for a nominal 4x4 column size, making it suitable for standard 4x4 structural posts and columns.

What corrosion protection does the CBS44 offer?

The CBS44 features a Zinc Galvanized G90 coating, which provides extra corrosion resistance and makes it well-suited for use in environments where exposure to moisture is a concern.
