Simpson Strong Tie ABA Adjustable and Standoff Post Bases
This item is a steel connector designed to attach wooden posts to existing concrete footings while providing a crucial 1-inch standoff to prevent wood rot. Its key feature is a slotted base that allows for a degree of flexibility and easier alignment around the anchor bolt during installation.
Key Features:
- 1-inch Standoff: The built-in standoff elevates the post end above the concrete to protect it from moisture and standing water, a design that meets code requirements for structural posts exposed to weather or water splash.
- Adjustability: A slotted anchor hole in the base allows for minor adjustments in post placement, making installation easier and more precise.
- Corrosion Resistance: The base is made from steel with a ZMAX galvanized finish, providing extra corrosion resistance for exterior and treated-wood applications.
- Material and Gauge: The ABA is typically made from 16-gauge steel for 4x4 posts and 14-gauge steel for 4x6 and 6x6 posts.
- Load Capacity: It offers increased uplift loads for earthquake or wind loading compared to basic post bases.
- Installation: It can be installed with either nails (e.g., 10d HDG nails for 4x4) or Simpson Strong-Drive SD Connector screws, and requires a concrete anchor bolt (e.g., 1/2-inch or 5/8-inch diameter, depending on the model)
