The Strong-Tie ABU Adjustable Post Base with Uplift is designed to attach wooden posts to existing concrete in high-capacity applications. The built-in 1" standoff of this adjustable post base helps to prevent rot at the end of the post. This versatile post base makes a cost-effective option for securing a post to the foundation, with a design built for maximum uplift performance.


  • A slotted hole for the concrete anchor allows for adjustment so you can achieve a perfect post alignment.
  • The ZMAX galvanized finish provides a level of corrosion resistance that is acceptable for use with treated lumber and normal outdoor use.
  • Has a slotted anchor hole in the base for adjustability and attaches to the post with nails, Strong-Drive® SD Connector screws or bolts


  • 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 Bolts - Use only the specified fasteners below.
  • Use nails OR bolts. DO NOT install nails and bolts together!
  • 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).

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
