Simpson Strong-Tie CBSQ44SS - 4x4 Stainless Steel Column Base with Quick-Install Design

The Simpson Strong-Tie CBSQ44SS is a stainless steel column base engineered to serve as the critical interface between columns and their concrete foundations. Designed specifically for 4x4 nominal column sizes, this column base transmits the full structural stresses of the column down to the concrete footing surface, providing a reliable and code-compliant load path from the post to the foundation. Built with a corrosion-resistant stainless steel finish, the CBSQ44SS is well-suited for demanding environments where long-term durability and finish integrity are essential. The CBSQ series utilizes Strong-Drive SDS Heavy-Duty Connector screws, which deliver fast installation, a reduced reveal profile, and a greater net section area of the column compared to traditional bolt-based systems - making this connector a professional-grade solution for structural post-base applications.

Key Features

• Structural Column-to-Foundation Interface: Engineered to link 4x4 columns directly to concrete footing surfaces, efficiently transmitting structural stresses to the foundation.
• Strong-Drive SDS Heavy-Duty Connector Screws: Enables fast installation with a reduced reveal and provides a greater net section area of the column than bolt-based alternatives.
• Stainless Steel Finish: Offers enhanced corrosion resistance for use in moisture-prone or corrosive environments.
• Quick-Install Design: The CBSQ series is purpose-built to streamline the installation process without sacrificing structural performance.
• Made in the United States: Manufactured domestically to Simpson Strong-Tie's rigorous quality standards.
• Reduced Reveal Profile: Screw-driven fastening system minimizes the standoff appearance at the base of the column.

Specifications

• Manufacturer: Simpson Strong-Tie
• Model Number (MPN): CBSQ44SS
• Column Size: 4x4
• Finish: Stainless Steel
• Fastener Type: Strong-Drive SDS Heavy-Duty Connector Screws
• Country of Origin: United States

Approved Applications

• Connecting 4x4 wood columns to concrete footing surfaces in structural framing applications.
• Residential and commercial deck post bases where a column-to-concrete connection is required.
• Covered outdoor structures, pergolas, and patio covers requiring a secure post base with corrosion-resistant hardware.
• Any application where structural loads must be transmitted from a 4x4 column down to a concrete foundation.

Note: Post bases 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 or unbraced carports).

Installation Guidelines

• Use all specified fasteners. See General Notes for complete fastener requirements.
• Install the CBSQ with the bottom of the standoff flush to the top of the concrete surface.
• Post bases do not provide adequate resistance to prevent members from rotating about the base and are not recommended for non-top-supported installations such as fences or unbraced carports.

Frequently Asked Questions

What column size is the CBSQ44SS designed to fit?

The CBSQ44SS is designed specifically for 4x4 nominal column sizes, making it suitable for standard 4x4 structural posts used in deck, pergola, and other load-bearing applications.

What type of fasteners are used with the CBSQ44SS?

The CBSQ44SS utilizes Strong-Drive SDS Heavy-Duty Connector screws. These screws enable fast installation, provide a reduced reveal profile, and deliver a greater net section area of the column compared to traditional bolt-based systems.

Why is stainless steel important for this column base?

The stainless steel construction of the CBSQ44SS offers enhanced corrosion resistance, making it well-suited for moisture-prone or corrosive environments where long-term durability and finish integrity are essential.

What is the structural purpose of the CBSQ44SS?

The CBSQ44SS serves as the critical interface between a 4x4 column and its concrete foundation. It transmits the full structural stresses of the column down to the concrete footing surface, providing a reliable and code-compliant load path from the post to the foundation.
