CBSQ Column Bases

The CBSQ uses Simpson's SDS screws, which allow for fast installation, reduced reveal and high capacity, providing a greater net section area of the column compared to bolts.

CBSQ86 and CBSQ88 now available.

Material: See table.

Finish: Galvanized, available in HDG with HDG screws.

Installation:

Use all specified fasteners. See General Notes.
Install Simpson’s 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).

To order with screws, specify CBSQ-SDS2.
To order without screws, specify CBSQ.
