Notice - This connector is designed for Rough Cut lumber NOT nominal lumber (most common). This will only fit a post that measures an actual 4x6". If you have a nominal post measuring 3-1/2x5-1/2" you will need an ABU46Z Post base

The Simpson Strong-Tie ABU series of adjustable post bases provide a 1" standoff for the post and are slotted for adjustability. The "R" series of post bases are designed exclusively for use with rough cut lumber. The ABU46RZ adjustable post base is approved to be installed with the specified nails, Strong-Drive SD connector screws or specified machine bolts. The Strong-Tie ABU46RZ 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.

• 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).

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