CBQGT Column Base

This product is only available in Canada

The CBQGT uses Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws, which allows for fast installation, reduced reveal, high capacity and provides a greater net section area of the column compared to bolts.


  • 7 gauge


  • Simpson Strong-Tie gray paint, available in HDG


  • Use all specified fasteners; see General Notes.
  • Install 1/4" x 2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column base. (Lag screws will not achieve the same load.)
  • Minimum 3" side cover on concrete is required.
  • 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).
  • Other sizes available. Check with Simpson Strong-Tie for details.

  2. Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. Values in the tables reflect installation into the wide face.
  3. Designer is responsible for concrete design.
  4. Factored resistances shown assume dry service condition (KSF = 1.00). Multiply table values by 0.67 under wet service conditions.
  5. Minimum f'c shall be 20 MPa.
