The Simpson ABU46SS 4x6 Adjustable Post Base - Stainless Steel is designed to securely attach wood posts to existing concrete, making it an essential component for your construction projects. This versatile post base is ideal for various applications and the additional uplift support makes this a good choice for jobs where high capacity uplift is necessary. Its built-in 1-inch standoff design helps prevent rot at the end of the post, ensuring durability and longevity.

One of the standout features of the ABU Adjustable Post Base is its slotted anchor hole, which allows for precise post placement, making installation more manageable. The post base can be attached using nails or Strong-Drive® SD Connector screws, providing flexibility and ease of use.

This product is intended for use with 4x6 lumber but is also available in other sizes, including double 2x, 4x4, 4x6, and 6x6, for both nominal and rough-cut lumber.


  • Increased Load Capacity: Engineered to withstand higher uplift loads, making it ideal for areas prone to earthquakes or high winds.
  • Versatile Application: Intended for use with 4x6 lumber with a slotted base for adjustable installation.
  • Enhanced Durability: The 1-inch standoff design meets code requirements and helps prevent post rot.
  • Maximum Corrosion Resistance: Stainless steel construction offers unmatched corrosion resistance and longevity, ideal for harsh environments.

-The slot in the base enables flexible positioning around the anchor bolt, making precise post placement easier
-The 1" standoff helps prevent rot at the end of the post and meets code requirements for structural posts installed in basements or exposed to weather or water splash


-Use all specified fasteners.
-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, load transfer plate and nut on the anchor bolt. Loosely tighten the nut.
-Place the standoff base and then the post in the ABU.
-Fasten using nails or Strong-Drive SD structural connector screws or bolts (ABU88, ABU1010 – SDS optional).
