The Simpson Strong-Tie CBST Column Base is engineered to provide solid, code-compliant support for wood columns in outdoor structures. Its standoff design elevates the column above concrete to prevent moisture damage, while the heavy-duty construction delivers strength and stability for a range of applications.

Hot-dip galvanized for corrosion resistance, this base is ideal for use in decks, patio covers, pergolas, and other exposed environments. The CBST model is cast with precision and accommodates multiple post sizes, making it a versatile solution for residential and light commercial builds.

Key Features:

• Standoff base elevates column 1" above concrete to reduce moisture contact
• Cast-in design provides exceptional strength for structural applications
• Made from heavy-duty steel and hot-dip galvanized for corrosion protection
• Compatible with multiple post sizes depending on selection
• Ideal for both new construction and retrofit projects
