The Simpson 4x6 Column Base Standoff in stainless steel is a structural connector engineered to create a secure, code-compliant connection between a 4x6 post or column and a concrete footing. Built by Simpson with a quick-install design, this standoff column base is well suited for structural posts in basements, columns exposed to weather or water splash, and any application where a dependable column-to-foundation interface is required.

Key Features

• Stainless Steel Construction - Provides superior corrosion resistance, making this column base a reliable choice for exterior installations, areas exposed to weather, and locations subject to water splash where standard finishes would degrade over time.
• Quick-Install Design - Designed for use with Strong-Drive SDS Heavy-Duty Connector screws, which allow faster installation compared to traditional bolts and reduce the disruption to the net section area of the column, helping structural professionals work more efficiently on the job site.
• 1-Inch Standoff Height - Elevates the column base of the post above the concrete footing surface, helping to prevent moisture contact at the base of the column and supporting code-compliant standoff clearance requirements.
• Engineered for 4x6 Column Size - Precisely sized to fit a 4x6 post or column, ensuring a proper structural fit without the guesswork or fitment issues that can arise from using an incorrectly sized base.
• Approved for Structural Applications - Suitable for column-to-concrete-footing connections in basements and weather-exposed installations, giving contractors and builders confidence that the connector meets recognized structural application requirements.

Why This Product

• Purpose-Built for Demanding Environments - The stainless steel finish is specifically suited for posts and columns exposed to weather or water splash, offering long-term durability in conditions where other finishes would be inadequate.
• Faster, Cleaner Installation - The quick-install design paired with Strong-Drive SDS Heavy-Duty Connector screws means less time on installation and a stronger, neater connection compared to conventional bolt-based column bases.
• Protective Standoff Clearance Built In - The 1-inch standoff keeps the bottom of the column elevated above the footing surface, reducing the risk of moisture-related damage and supporting code-compliant structural post installations without additional modification.
• Trusted American-Made Quality - Produced under the quality standards that Simpson is known for, this column base connector reflects consistent manufacturing and material integrity for structural professionals who cannot afford connection failures.
