Simpson Strong Tie 6x6 Adjustable Post Base - Zmax Finish
The ABA is designed to attach wooden posts to existing concrete. The built-in 1" standoff of this adjustable post base helps to prevent rot at the end of the post. The ABA has a slotted anchor hole in the base for adjustability and attaches to the post with nails or Strong-Drive® SD Connector screws. This versatile post base makes a cost-effective option for securing a post to the foundation.
This post base is available in model sizes for double 2x, 4x4, 4x6 and 6x6 lumber, both nominal and rough. The new double 2x size can be used for installing a structural post consisting of two 2x4 studs nailed together as well as for securing double 2x beams to a footing for ground-level decks.
- The slot in the base enables flexibility around the anchor bolt, making precise post placement easier
- 1" standoff design meets code requirements for structural posts installed in basements or exposed to weather or water splash
- Increased uplift loads for earthquake or wind loading
