The Simpson 10 x 12 Column Base is a heavy-duty structural connector from Simpson engineered to anchor large posts securely to concrete foundations. Designed for cast-in-place or wet-set installation, the base plate sits flush with the concrete surface to deliver full post bearing and exceptional load transfer. Built for demanding residential, commercial, and industrial applications - including structures subject to high wind and seismic forces - this column base supports lumber, glulam, and engineered wood product posts with reliable, long-term structural performance.

Key Features

• Compatible with lumber, glulam, and engineered wood products - gives builders flexibility to use the post material that best suits their structural design without needing a different connector.
• Cast-in-place and wet-set installation methods supported - accommodates common concrete foundation workflows so contractors can integrate this base into their preferred jobsite process.
• Base plate sits flush with the concrete surface - provides full post bearing, maximizing load transfer from the column down into the foundation for improved structural integrity.
• Engineered for high uplift resistance in wind and seismic load zones - makes this column base a dependable choice for projects where structural connectors must meet rigorous lateral and vertical force requirements.
• Finished in Simpson gray paint - provides a consistent, professional appearance while offering a baseline level of surface protection suited to structural hardware applications.
• Domestically produced - reflects a commitment to consistent manufacturing standards that contractors and engineers can count on across projects.
