Simpson Strong-tie ABW66Z Zmax Adjustable Post Base 6x6

Product Description

The SIMPSON STRONG-TIE ABW66Z is an adjustable retrofit post base designed for 6x6 lumber posts in residential and light commercial structural applications. It features a 1-inch standoff that elevates the post end off the concrete surface, reducing moisture contact and helping prevent rot. The ZMAX finish provides a heavy-gauge galvanized coating suited for treated lumber and corrosive environments. The base is engineered with increased capacity to resist uplift loads, making it appropriate for structural posts subject to wind or seismic loading. Licensed contractors, framers, and structural trades install this connector as part of deck, porch, carport, and basement column framing systems.

The ABW66Z is used in residential decks, covered porches, carports, and basement structural column applications where posts are subject to weather, water splash, or code-required standoff clearance. The slotted design allows flexible positioning around an existing anchor bolt, which simplifies post placement during retrofit installations. It is well suited for pressure-treated lumber environments and applications where local building codes require a standoff post base for posts installed in basements or exposed exterior conditions.

Installation Notes

Installation should be performed by a qualified framing contractor or structural trades professional in accordance with applicable local building codes and the manufacturer's load tables. Before installation, verify the anchor bolt location and concrete substrate condition. Place the standoff base over the anchor bolt, set the post, and fasten on three vertical sides before bending and fastening the fourth side. Always consult the published Simpson Strong-Tie installation instructions and applicable code references for required fastener schedule and inspection requirements.
