Product Details

Post and column bases secure the bottom of posts or columns to concrete and are perfect for decks or patio covers. Models are available for attaching to existing hardened concrete, wet concrete, as well as wood. The CBSQ series provides a connection between a post (or column) for decks, patio covers and other top-supported structures.
  • Uses Strong-Drive screws, which allow for fast installation, reduced reveal and high capacity
  • Provides a 1-in standoff between post and concrete that meets code requirements
  • Embeds in wet concrete at time of pour
  • The standoff base reduces the potential for decay at post and column ends
  • Shipped with base plate assembled
  • Nominal column size: 4x4
  • Steel gauge: Base 12; strap 10
  • Galvanized (G90) for extra corrosion resistance

    Q:could i use this for the bottom post of a stair railing?
    by|Jul 10, 2023
    1 Answer
    Answer This Question

    A:  ​Hi davey76, this is Colin from Simpson Strong-Tie. The CBSQ standoff post base series does not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top supported installations. An alternative option that does provide resistance to rotation at the base, is our MPBZ Moment Post Base. If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you.

          Simpson Strong-Tie CBSQ, meets local building codes. Comes with the correct screws. Probably the best product of this type for embedding in concrete. Used for 6"x6" treated posts on top of retaining wall for Pole Barn. Shipped in a reasonable amount of time. Was able to buy the exact number I needed from Home Depot (many suppliers sell in increments of 6 per box).

          Notice the size
          I used the 6x6 base to erect our mail boxes. The post is a full 6 inches, but the gap width between the two plates is 5’3/4, so had to chisel off some wood to make the post slide into the base. Other than that this is a solid strong product.
