Frequently Asked Questions
- What size post is the BC60Z designed for?
- The BC60Z is designed for a nominal 6x post size, providing a secure connection between the base of a 6x post or column and the concrete surface below.
- Why is ZMAX galvanization important for this post base?
- ZMAX galvanization offers extra corrosion resistance compared to standard galvanized finishes, making the BC60Z especially suitable for exterior applications and installations involving treated lumber, where moisture and chemical exposure can accelerate corrosion.
- Can the BC60Z be used for fences or unbraced carports?
- No. The BC60Z is not recommended for non top-supported installations such as fences or unbraced carports. Post bases do not provide adequate resistance to prevent members from rotating about the base in those types of applications.
- What fasteners should be used to install the BC60Z?
- Install with 16d commons or 16d x 2 1/2" joist hanger nails. All specified fasteners must be used: the post flange requires (6) 0.162 x 3-1/2" nails and the base bottom requires (4) 0.162 x 3-1/2" nails. Do not install bolts into pilot holes.
