Frequently Asked Questions
- What type of concrete can the ABW44Z be installed into?
- The ABW44Z is designed for installation into existing hardened concrete, making it suitable for attaching posts to already-cured concrete footings and slabs on decks, patio covers, and similar top-supported structures.
- Why does the ABW44Z feature a 1-inch standoff?
- The 1-in. standoff lifts the base of the post above the concrete surface, which helps prevent direct contact with moisture that can accumulate on concrete. This design feature helps avoid post-end rot, extending the service life of the post in exterior applications.
- What fasteners are required to install the ABW44Z?
- The ABW44Z is approved for installation with 10d common nails or #9 x 1-1/2 in. Strong-Drive SD screws. Because the base features a ZMAX (G185) galvanized finish, hot-dip galvanized fasteners meeting the specifications of ASTM A153 are required to maintain compatibility with the coating.
- What is ZMAX galvanization and why does it matter for this post base?
- ZMAX is a G185 hot-dip galvanized coating applied to the 16-gauge steel base that provides a significantly thicker zinc layer than standard galvanization. This extra corrosion resistance makes the ABW44Z especially well-suited for exterior environments and applications involving treated lumber, where contact with preservative chemicals could accelerate corrosion on lesser-coated hardware.
