Simpson Strong Tie ABW46Z Adjustable Post Base Zmax

Product Description

The SIMPSON STRONG TIE ABW46Z is a Zmax galvanized adjustable post base designed to anchor structural posts above concrete surfaces in residential and light commercial construction. The raised standoff design keeps wood posts clear of moisture at the base, reducing the risk of rot and decay over time. Zmax galvanization provides a heavy zinc coating that resists corrosion in outdoor and treated-lumber environments. The connector is rated for increased uplift load resistance, adding lateral and vertical stability to post-frame assemblies. Licensed contractors and structural carpenters install this connector per applicable building codes and engineered drawings.

The ABW46Z is suited for deck posts, pergola columns, carport framing, and similar outdoor structural applications where posts must be set above a concrete footing or slab. The adjustable base allows minor positioning corrections during layout, making it practical for both new construction and replacement installations. It performs reliably in coastal, high-humidity, and pressure-treated-lumber environments where standard zinc plating would corrode prematurely.

Key Features

• Zmax galvanized finish for superior corrosion resistance in outdoor and treated-lumber applications
• Adjustable post base design allows field positioning adjustments during installation
• Raised standoff keeps post base clear of concrete surface to prevent moisture contact
• Increased uplift load capacity for greater structural stability
• Installs with a 1/2 inch anchor bolt plus eight 10D common nails or 9 x 1.5 inch Strong-Drive screws
• Sold in a package of 10 connectors

Compatibility

Designed as an OEM-style structural post base connector for use with standard dimensional lumber posts in residential and light commercial framing applications anchored to concrete footings or slabs.

Installation Notes

Installation should be performed by a licensed contractor or qualified framing carpenter familiar with applicable building codes, including IRC and IBC fastener and connector requirements. Set the anchor bolt in concrete before positioning the base, and allow concrete to fully cure before applying structural loads. Use only the specified fastener types and counts to achieve the rated load values. Do not substitute fastener sizes or reduce fastener count, as doing so will reduce connector capacity below rated values.
