Notice - This connector is designed for Rough Cut lumber NOT nominal lumber (most common). This will only fit a post that measures an actual 4x4". If you have a nominal post measuring 3-1/2x3-1/2" you will need an ABU44Z Post base

The Simpson ABU44RZ Rough Cut 4x4 Adjustable Post Base - Zmax Finish 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 Rough Cut 4x4 lumber but is also available in other sizes, including double 2x, 4x4, 4x6, and 6x6, for both nominal and rough-cut lumber.
