Simpson Column Bases

Column bases support larger columns in substantial structures, such as large decks and covered patios. They provide firm structural support and enhanced stability under heavy loads.

Types of Column Bases

  • Standoff Column Bases: Elevate the post or column above the concrete foundation to prevent moisture contact.
  • Non-standoff Column Bases: Installed directly on the concrete slab, suitable where moisture is not a major concern.

Simpson Standoff Column Bases

  • CBS/CBSQ Column Bases: These bases secure columns to their concrete foundations, effectively transmitting structural stresses to the foundation.
    • CBS: Installed using standard hardware, offering flexibility in hardware choices.
    • CBSQ: Includes Strong-Drive® SDS Heavy-Duty Connector screws for faster installation and a cleaner look.
  • ECB Elevated Column Bases: The ECB elevated column base offers a 2-inch standoff height, allowing for easy installation of waterproofing materials while maintaining required clearance to keep posts dry and prevent decay.

Simpson Non-Standoff Column Bases

  • CB Column Bases: The CB column base anchors posts to concrete foundations, accommodating various materials and ensuring high structural integrity and durability.
