Simpson Strong-Tie ABA66RZ Rough 6x6 Post Standoff


The AB series of retrofit adjustable post bases provide a 1" standoff for the post, are slotted for adjustability and can be installed with nails, Strong-Drive® SD Connector screws or bolts (ABU). Depending on the application needs, these adjustable standoff post bases are designed for versatility, cost-effectiveness and maximum uplift performance.

Key Features

  • 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


  • Varies (see model table)


  • All galvanized. Most offered in ZMAX® coating. See Corrosion Information.


  • Use all specified fasteners; see General Notes.
  • See our Anchoring and Fastening Systems for Concrete and Masonry catalog for retrofit anchor options or reference technical bulletin Anchoring Solutions for Simpson Strong-Tie® Connectors in Wind and Low-Seismic Regions (T-ANCHORSPEC).
  • 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.
  • Some products may be installed with the Strong-Drive® SD Connector screw; see model table.
