Simpson Strong-Tie ABA Adjustable Post Base
Available Inventory:
13
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.
Key Features
- The slot in the base enables flexibility around the anchor bolt, making precise post placement easier

- 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).
- Place the base, cut washer(s) and nut(s) on the anchor bolt(s). Make any necessary adjustments to post placement and tighten the nut securely on the anchor bolt.
- Place the post in the ABA and fasten using nails or Strong-Drive SD Connector screws.
