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

Material: See table.

Finish: Galvanized, available in HDG with HDG screws.

Installation:

• Use all specified fasteners. See General Notes.
• Install Simpson Strong-Tie SDS 1/4"x2" wood screws, which are provided with the column base. (Lag screws will not achieve the same load.)
• For full loads, a minimum of 3" side cover shall be provided.
• 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).

1. For higher downloads, solidly pack grout under 1" standoff plate before installing CBSQ into concrete. Base download on column or concrete, according to the code.
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. See technical bulletin T-C-SCLCLM for values on the narrow face (edge).
3. Downloads shall be reduced where limited by the capacity of the column. See Post Capacities for common post allowable loads.
4. Designer is responsible for concrete design.
