Frequently Asked Questions
- What size lumber is the ABW46RZ designed for?
- The ABW46RZ is designed exclusively for use with rough cut 4x6 lumber. The "R" designation in the model number indicates it is made specifically for rough-cut member sizes, not standard dimensional lumber.
- What fasteners should be used to install the ABW46RZ?
- This post base is approved for installation with 10d common nails or #9 x 1-1/2 in. Strong-Drive SD connector screws. Because of the ZMAX coating, hot-dip galvanized fasteners meeting ASTM A153 specifications are required.
- Why does the ABW46RZ feature a 1 in. standoff?
- The 1 in. standoff elevates the base of the post above the concrete surface, helping to prevent moisture from collecting at the post end. This design feature significantly reduces the risk of rot and extends the service life of the post in exterior applications.
- What makes the ZMAX finish suitable for exterior and treated-wood use?
- The ZMAX galvanization provides a heavy-duty G185 galvanized coating that delivers extra corrosion resistance compared to standard galvanized finishes. This makes the ABW46RZ well-suited for outdoor environments and direct contact with pressure-treated lumber, which can accelerate corrosion in standard hardware.
