Simpson Strong Tie ABW66Z Adjustable Post Base 6x6

Product Description

The SIMPSON STRONG TIE ABW66Z is an adjustable post base designed for 6-inch x 6-inch nominal lumber posts in structural construction applications. The base features a 1-inch standoff that elevates the post end off the bearing surface, reducing direct moisture contact and the rot risk that comes with it. The main body is formed from 12-gauge steel and the strap from 14-gauge steel, delivering the load transfer and uplift resistance required in demanding framing conditions. ZMAX galvanization provides a heavy zinc coating for corrosion resistance in exterior and treated-lumber environments. Licensed contractors and professional framers are the primary installers of this hardware.

The ABW66Z is suited for residential and light commercial framing where 6 x 6 posts are anchored to concrete foundations, footings, or slab surfaces. Typical applications include deck posts, porch columns, pergola uprights, and structural support columns where a code-compliant, corrosion-resistant connection between post and concrete is required. The adjustable design allows for minor positional corrections during layout. Installation uses 1/2-inch anchor bolts along with nails or screws through the strap, keeping fastener requirements straightforward. The package contains 10 bases per unit of measure.

Installation Notes

Installation is typically performed by licensed general contractors or professional framers working to local building code and IRC or IBC requirements. Anchor bolts should be set and cured in the concrete footing before the post base is attached. Ensure the anchor bolt is properly positioned and plumb before final fastening. Follow the manufacturer load table and local AHJ requirements for fastener count and type.
