Simpson ABU44Z 4x4 Adjustable Post Base - Zmax Finish

The Strong-Tie ABU series of adjustable post bases provide a 1" standoff for the post and are slotted for adjustability. The Simpson ABU44Z adjustable post base is approved to be installed with the specified nails, Strong-Drive SD connector screws or specified machine bolts. The Simpson Strong-Tie ABU44Z post base features a G185 ZMAX galvanized finish for added corrosion resistance and requires the use of hot-dip galvanized fasteners which meet the specifications of ASTM A153.

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

Installation:

• 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.

ABU

• 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).

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